Lead Acid batteries have changed little since the 1880's although improvements in materials and manufacturing methods continue to bring improvements in energy density, life and reliability. Lead acid batteries used in the RV and Marine Industries usually consist of two 6-volt batteries in series, or a single 12-volt battery. A battery cell consists of two lead plates a positive plate covered with a paste of lead dioxide and a negative made of sponge lead, with an insulating material (separator) in between. Build your own Accurate LC Meter (Capacitance Inductance Meter) and start making your own coils and inductors. 1Hz - 2MHz XR2206 Function Generator produces high quality sine, square and triangle waveforms of high-stability and accuracy. Having the ability to control various appliances inside or outside of your house wirelessly is a huge convenience, and can make your life much easier and fun. If your '); return false">battery has removable vent caps then they can be pried off with a flat-head screwdriver.
Battery terminals should be cleaned periodically with a mixture of baking soda and water and wire brush if necessary. It would be helpful if you added a diagram or cross section showing proper water level relative to the fill tube and plates.
Features: 1)The MCA FC series AGM lead acid batteries adopt tight assembly has excellent discharge performance and cycle ability. A lead acid battery is made of a number of lead acid cells  wired in series in a single container. To avoid these problems, valve regulated lead acid (VRLA) batteries prevent the movement of the electrolyte inside the container, trapping the hydrogen near the plates, making them readily available for re-combination as the battery is recharged.
With all the alternative sources of energy being explored and implemented; we are seeing a rising trend in demand of Lead acid batteries. These batteries are constructed of several single cells connected in series each cell produces approximately 2.1 volts.
The plates are enclosed in a plastic battery case and then submersed in an electrolyte consisting of water and sulfuric acid (see figure # 1). This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. BA1404 HI-FI Stereo FM Transmitter broadcasts high quality stereo signal in 88MHz - 108MHz FM band.
It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
8-DIP machined IC socket allows to swap OPA2134 with many other dual opamp chips such as OPA2132, OPA2227, OPA2228, dual OPA132, OPA627, etc. It's breadboard compatible so it can be plugged into a breadboard for quick prototyping, and it has VCC & GND power pins available on both sides of PCB. To find what you're after, use the search box below or choose a category to view listed questions. The terminals should be rinsed with clean water and then can be coated with a commercially available sealant or high temperature grease. 2)The use of heavy-duty lead-calcium alloy grids with anticorrosive construction, ensures long service life 3)There is no need to check the electrolyte level, nearly no decrease in liquid.
Lead acid cells have two plates of lead hung in a fluid-like electrolyte solution of sulfuric acid.
Since this reverse process is not perfect, hydrogen gas is released before it can completely mix with the water inside the battery container.  To prevent the build up of the hydrogen gas (which may cause the battery to explode), a vent is used to relieve the pressure.
Gel Cell Batteries are primarily used in electric wheelchairs, certain recreational vehicles, generators and more.
Deep-cycle AGMs are also commonly used in off grid solar power and wind power installations as an energy storage bank and in large-scale amateur robotics, such as the FIRST and IGVC competitions.
However, these batteries have a high cost and you will need to spend quite some money to replace them (average life of commercially available deep cycle batteries is 1.5-2 years) when they die out on you.
Regular water addition is required for most types of lead acid batteries although low-maintenance types come with excess electrolyte calculated to compensate for water loss during a normal lifetime. A six-volt battery has three single cells, which when fully charged produce an output voltage of 6.3 volts. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.
It's small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.
Look down into each individual cell to make sure that the water is covering the lead plates and is at the proper level. This is where we come in with our guide on how to rebuild a battery from your dead battery. A twelve-volt battery has six single cells in series producing a fully charged output voltage of 12.6 volts. Lead acid batteries do not generate voltage on their own; they only store a charge from another source. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.
To regulate these events, a one-way pop-off valve is incorporated into the battery body which only opens when the pressure builds up.  The immobilizer used in these batteries ensures that there would be no spillage or leakage of the liquid inside. This is the reason lead acid batteries are called storage batteries, because they only store a charge.
USB IO Board is self-powered by USB port and can provide up to 500mA for electronic projects.
Board features 28-PIN DIP IC socket, user replaceable ATmega328 microcontroller flashed with Arduino bootloader, 16MHz crystal resonator and a reset switch.

Always use distilled water that is available from a supermarket to fill the battery in order to prevent chemicals from contaminating the battery.
5) MCA VRLA Lead-acid batteries use gas recombination system which transforms the generated gas into water, features improved recombination efficiency. Alright, so how do you build a battery from an existing dead battery and more importantly why does the battery die?
The size of the battery plates and amount of electrolyte determines the amount of charge lead acid batteries can store. Arduino sketches are uploaded through any USB-Serial adapter connected to 6-PIN ICSP female header. Board is supplied by 2-5V voltage and may be powered by a battery such as Lithium Ion cell, two AA cells, external power supply or USB power adapter.
This chemical reaction also begins to coat both positive and negative plates with a substance called lead sulfate also known as sulfation (shown as a yellow build-up on plates). This results in a decrease in battery’s capacity and consequently failure.You can recover the oxides (covered later in the article) from the positive plates that have fallen victim to the anodic corrosion and use it to make paste for the new plates. So; we will be using the negative plates to make a new cell with the paste that comes from oxides. Lead sulfate is a soft material, which can is reconverted back into lead and sulfuric acid, provided the discharged battery is immediately connected to a battery charger.
This means that you’ll be building a 3 cell battery from 6 cell battery.Advertisement Now to get to the job’ remove the positive plates and have them placed in a metal container, which can take some beating. Use a hammer or anything that is hard that can transfer impact to turn these plates into powder. Proper recharging and maintenance requires an intelligent charging system that can vary the charging voltage based on the state of charge and use of your RV or Marine battery. Once you have crushed the plates, remove small pieces of lead and grid from the mixture by sieving the contents.
In order to recharge a 12-volt lead acid battery with a fully charged terminal voltage of 12.6-volts, the charger voltage must be set at a higher voltage.
Mix this powder with sulfuric acid and water to form a paste which will be placed into the plate’s grid structure and cured.
During the battery recharge cycle lead sulfate (sulfation) begins to reconvert to lead and sulfuric acid. During the recharging process as electricity flows through the water portion of the electrolyte and water, (H2O) is converted into its original elements, hydrogen and oxygen.
Mix the fiberglass and glass fibers that have been recovered from the separators to strengthen the paste.
These gasses are very flammable and the reason your RV or Marine batteries must be vented outside. Once the paste has been applied you will need to cure the plates, which is usually done at 30 degree Celsius in high humidity for about 48 hours. Gassing causes water loss and therefore lead acid batteries need to have water added periodically.
At home, just put them in a pot that is filled with water into the oven and keep an eye on the water level. Sealed lead acid batteries contain most of these gasses allowing them to recombine into the electrolyte. If the battery is overcharged pressure from these gasses will cause relief caps to open and vent, resulting in some water loss. First off, cut the top off the battery and leave about 5 mm of plastic around the terminals.
Now you need to cut the interconnection between the cells and remove the cells from the case.Now you need to perform the process of forming in which, active materials are formed on the new plates. This build-up will continue after each recharging cycle and gradually the battery will begin to loose capacity to store a full charge and eventually must be replaced. The idea is to pass electric current and then reverse the direction and continue the same procedure for about say 30 times. Lead sulfate build up is reduced if battery is given an Equalizing Charge once every 10 discharge cycles or at least once a month. If you continue indefinitely you’ll destroy the plate.Let’s make some electrolyte, shall we? An Equalizing Charge increases charging voltage to 14.4 volts or higher for a short period. This higher voltage causes gassing that equalizes (re-mixes) the electrolyte solution. Since most RV and Marine craft owners seldom remember to perform this function, Progressive Dynamics has developed the microprocessor controlled Charge Wizard. The Charge Wizard will automatically provide an Equalizing Charge every 21 hours for a period of 15 minutes, when the battery is fully charged and not in use. Alternatively, you can buy a sulphuric acid solution with 1250 sp gravity from a battery shop to use as a battery electrolyte. Now all that is left is placing the plates back into the case, sealing the top and filling it with electrolyte. A typical 125-AH RV or Marine battery will take approximately 80 hours to recharge at 13.6 volts. Increasing the charge voltage to 14.4-volts will reduce battery recharge time for a 125-AH battery to 3-4 hours. The optional Charge Wizard automatically senses when a battery has a very low state of charge and automatically selects its BOOST MODE of operation.
When the battery reaches the 90% charge level, the Charge Wizard automatically reduces the charge voltage down to 13.6 volts to complete the charge.
If you still decide to do it, make sure to work very safe as the lead-acid is very dangerous. The Charge Wizard will automatically select its STORAGE MODE of operation (13.2-volts) once the battery reaches full charge and remains unused for a period of 30 hours.
However, this lower voltage does not provide enough gassing to prevent a battery condition called Battery Stratification. Battery Stratification is caused by the fact that the electrolyte in the battery is a mixture of water and acid and, like all mixtures, one component, the acid, is heavier than water. Therefore, acid will begin to settle and concentrate at the bottom of the battery (see figure #8). This higher concentration of acid at the bottom of the battery causes additional build-up of lead sulfate (sulfation), which reduces battery storage capacity and battery life. In order to prevent Battery Stratification, an Equalization Charge (increasing charging voltage to 14.4-volts) must be applied periodically. The Charge Wizard automatically selects its EQUALIZATION MODE (14.4 volts) every 21 hours for a period of 15 minutes.
This Equalizing Charge feature is standard on our Marine chargers. As you have learned, in order to properly charge and maintain a lead acid battery you must use an intelligent charging system.

Progressive Dynamics, Inteli-Power 9100 Series RV converters with a Charge Wizard installed, or one of our Inteli-Power Marine Battery Chargers will provide the intelligent charging system your battery needs for a long life, with low maintenance. Dry cells Batteries are split between dry cell and wet cell. Required fields are marked *CommentName * Email * Website Notify me of follow-up comments by email. The old original dry cells were the kind with a carbon rod down the middle, and they had little power and shelf life. Current non-rechargeable dry cells have an excellent shelf life and generally provide 1.5VDC. Rechargeable dry cells have a shelf life of less than a year before needing to be charged again. NiCads have given rise to the idea of batteries having a memory. Failing to fully discharge a NiCad before recharging it eventually led to a loss of battery life. There is no need to "condition" these batteries, and it is better to keep them on a float charge and fully charged than it is to cycle them by discharge then recharge. Cycling a battery makes it wear out faster. Wet cells Wet cells are the batteries we have in our cars - an acid and lead plates that generate electricity.
Sealed lead-acid batteries will not leak, although they may discharge gasses if not charged properly.
Gel cells are said to work better than AGM batteries in conditions where they have long use and frequent cycling.
The batteries are more deeply discharged and are used frequently, then recharged. AGMs seem more efficient at uses where they are deeply discharged but only infrequently, being kept on a floating charge. The battery in a UPS is kept fully charged while the power is on, but when the power goes off, the computers, monitors, printers, and such pull a lot of current from the battery until they can be shut down properly. The differences between gel cells and AGMs may make no difference to non-critical users who need a big capacity, portable battery for occasional use.
This may include ham radio operators who need a big battery for a day or two in the field for an event or for campers who want a battery on camping trips to run lights or to recharge AAs. Discharge Using a charged battery discharges it. If the battery has a manual, it may have a chart showing different capacities based on different draws.
When the battery shows 10V at the terminal with no load, the manufacturer deems the battery fully discharged.
Smaller amperages will take longer to charge and may not ever fully charge a big enough battery. Sealed batteries have one-way valves to vent the gas, but remember the gas is hydrogen, which is flammable. This means you will still be charging the battery as long as the charger is connected, and you will overcharge the battery. Battery life Battery life depends on many factors, and I'll cover only cycles. A sealed lead-acid battery which is fully discharged (as defined above) has a life of about 200 cycles.
If a battery is subject to "shallow" discharges (30% or 40% down from the voltage read when fully charged), then the life may be 800 or more cycles. It is better to keep a sealed lead-acid battery on a floating charge than to allow it to fully discharge by sitting a year between uses.
The next best option is to fully recharge the battery monthly. People who use their batteries infrequently and then use them to full discharge (and beyond) will damage their batteries and shorten the battery's life substantially from any advertised life. They don't recharge their batteries until a day or two before they leave, drain the batteries dead during the week, then bring the batteries home and put them away discharged until next year. If you have a 12 amp-hour battery and fully charge it, connect the lamp and volt meter to the battery, turn the lamp on, and note the time. When you notice the light fading, start watching the meter and note the time the voltmeter reads 10.5V. Its capacity will continue to degrade until you find the battery useless and recycle it. Answers to Common Questions about Batteries Do lead acid batteries discharge when not in use? All batteries, regardless of their chemistry, will self-discharge.
The rate of self-discharge for lead acid batteries depends on the storage or operating temperature. A battery with a 125-amp hour rating would self-discharge at a rate of approximately five amps per week.
Keeping this in mind if a 125 AH battery is stored for four months (16 weeks) winter without being charged, it will loose 80 amps of its 125-amp capacity. An equalizing charge prevents battery stratification and reduces sulfation, the leading cause of battery failure. When should I add water to my batteries? How often you use and recharge your batteries will determine the frequency of watering. It is best to check your battery water level frequently and add distilled water when needed. Tap water contains minerals that will reduce battery capacity and increase their self-discharge rate. Warning - A brand new battery may have a low electrolyte level.
Adding water to a battery before charging may result in overflow of the electrolyte. What is the proper electrolyte level? Battery electrolyte levels should be just below the bottom of the vent well, about ? - ? inch above the tops of the separators. Never let the electrolyte level to drop below the top of the plates. Do I ever need to add acid to my battery? Under normal operating conditions, you never need to add acid. Only distilled or deionized water should be added to achieve the recommended electrolyte levels. Can my batteries freeze? If your battery is partially discharged, the electrolyte in a lead acid battery may freeze. At a 40% state of charge, electrolyte will freeze if the temperature drops to approximately -16 degrees F.
When a battery is fully charged the electrolyte will not freeze until the temperature drops to approximately -92 degrees F. What are the most common mistakes made by owners of lead acid batteries? Undercharging - Generally caused by not allowing the charger to restore the battery to full charge after use.
Continuously operating a battery in a partial state of charge, or storing the battery in the discharged state results in the formation of lead sulfate (sulfation) on the plates. Sulfation reduces the performance of the battery and may cause premature battery failure. Overcharging - Continuous-charging causes accelerated corrosion of the positive plates, excessive water consumption and in some cases, damaging temperatures within the battery. Lead acid batteries should be charged after each discharge of more the 50% of its rated capacity and during or after prolonged storage of 30 days or more. Under-watering - In lead acid batteries water is lost during the charging process. Check your battery water level frequently. Over-watering - Excessive watering of a battery results in additional dilution of the electrolyte, resulting in reduced battery performance. Add water to your battery after it has been fully charged, never when the battery is partially discharged. Can I reduce the need to add water to my battery by lowering the charging voltage to 13 volts or less? Lowering the charging voltage will reduce the need to add water, but this will cause a condition known as battery stratification. Battery stratification is caused when the sulfuric acid in the electrolyte mixture separates from the water and begins to concentrate at the bottom of the battery. This increased concentration of acid increases the formation of lead sulfate (sulfation). To prevent stratification, your battery should receive a periodic equalizing charge (increasing the charging voltage to 14.4 volts or above).
