Lead acid batteries should be charged in three stages, which are [1] constant-current charge, [2] topping charge and [3] float charge. The switch from Stage 1 to 2 occurs seamlessly and happens when the battery reaches the set voltage limit.
Once fully charged through saturation, the battery should not dwell at the topping voltage for more than 48 hours and must be reduced to the float voltage level.
These described voltage settings apply to flooded cells and batteries with a pressure relief valve of about 34kPa (5psi).
Aging batteries pose a challenge when setting the float charge voltage because each cell has its own unique condition. Measuring the open circuit voltage (OCV) while in storage provides a reliable indication as to the state-of-charge of the battery. Some buyers do not accept shipments of new batteries if the OCV at incoming inspection is below 2.10V per cell. Watering is the single most important step in maintaining a flooded lead acid battery; a requirement that is all too often neglected. The formation of gas bubbles in a flooded lead acid indicates that the battery is reaching full state-of-charge. If your golf trolley is discharging your batteries when not being used, you must have a short circuit or partial short in the speed controller or wiring. I would like to ask you two questions regarding the process of charging sealed lead acid batteries, i would be so grateful for you for taking in consideration a simple answer as i am so far from the technology of batteries. 1)- I bought 2 new 6v 10Ah sealed lead acid batteries to use instead of the dead ones in my child’s ride-on, i also bought a simple wall charger which states that it charges at 1Ah, does this mean that to charge them for the 1st time i should leave them connected to the mains for 10 hours? 2)- I also have a 12v 1.5Ah charger, can i connect those 2 new 6v 10Ah batteries in series and charge them together and how much time would they take to be fully charged.
More of a question:  Is it possible for a 6 volt charger to charge a automobile 12 volt lead acid battery to the point where it will have enough energy to start a car? Can i use Sealed maintenance free batteries instead of Electrolyte filled ( Distilled water recharge )lead acid batteries.
For connecting the battery as a buffer I just nead to conect in parallel the battery with my device and the charger? I have a two year old car battery which gives enough power to start my car when cold , but it refuses to crank the engine after the car runs for more than 10 kms. I tested this battery, It initially read 12.76V, and I had applied a top-up charge using a 600ma smart charger intended for smaller batteries.
I connected a paralell series of 3x 15 ohm,  and 3x 22 Ohm, 10W resistors, with a 1 ohm 10W resister in series with the combination, to use as a current indicator.
As expected on connection, the voltage dropped very quickly, and the current was below what would be expected for the voltage. I believe this effect was due to thermal changes, and a delay in the chemical reactions in the battery, mentioned elsewhare in article on battery perfomance. Most guides to rested open circuit voltage suggest that with an open circuit voltage of 12.26V, the battery is about 65% cahrged.
These statement would indicate that the battery is in good condition, and close to stated capicity. Is the rapid change in discharge curve normal, or does that indicate there could be a fault?
This page is a good reference about lead acid Battery charging, but few points are incorrect, but not fatal mistake. I set up a 50W network of resistors to create a loat to discharge them and graphed the in-circuit terminal voltage and current over a period of 25 hours. The Terminal voltage initially dropped very quickly from it’s resting state, then took about 30 mins to stabilise. The calculated AH removed from the battery and the open circuit voltage after the test both indicated about 40% drain re the stated 220AH capacity of the battery. How much charging current is required for charging above batteries in parallel connection condition.
PS.This kind of discharging test is really not necessary and it is unwise because it will damage your battery. It is easy to charge with a higher voltage to a lower voltage, in your case, a 12V to a 6V. Alessandro Volta in 1789 took a copper rod and a zinc rod and immersed them both in an acetic acid solution. Between 1890 and the 1970's, dry cell batteries increased in popularity, but there were no significant changes in design. Primary battery construction ranges from the basic construction used in carbon zinc and zinc chloride batteries to the more complex construction of more powerful batteries such as alkaline and lithium manganese. In alkaline batteries, the zinc anode is a zinc powder in the center of the can, surrounding a brass current collector.
Lead Acid Battery cells consist of a Lead (Pb) electrode and a Lead oxide (PbO2) electrode immersed in a solution of water and sulfuric acid (H2SO4). Common examples of Lead acid batteries are car batteries, alarm system backup batteries, and camcorder batteries.
No more than six months, varies by temperature (longer at non-freezing low temperatures, shorter at high temperatures). Lithium batteries have a lithium foil anode, a manganese dioxide cathode, and a lithium-based electrolyte. The Nickel-cadmium battery uses nickel oxide in its positive electrode (cathode), a cadmium compound in its negative electrode (anode), and potassium hydroxide solution as its electrolyte. The Nickel-Metal Hydride (NiMH) battery was introduced as another option to the Nickel-Cadmium batteries. Two types of Silver Oxide batteries are available, one type with a sodium hydroxide (NaOH) electrolyte and the other with a potassium hydroxide (KOH) electrolyte.
The Silver Oxide battery has a higher closed circuit voltage than a Mercuric Oxide battery and a flatter discharge curve than the Alkaline Manganese Dioxide battery.


Zinc air batteries operate very similarly to other button-cell batteries, with the significant difference being that other button-cell batteries are entirely self-contained.
A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The constant-current charge applies the bulk of the charge and takes up roughly half of the required charge time; the topping charge continues at a lower charge current and provides saturation, and the float charge compensates for the loss caused by self-discharge. The topping charge is essential for the well-being of the battery and can be compared to a little rest after a good meal. A warmer ambient requires a slightly lower voltage threshold and a colder temperature prefers a higher setting. This is especially critical for sealed systems because they are less tolerant to overcharge than the flooded type. Cylindrical sealed lead acid, such as the Hawker Cyclon cell, requires higher voltage settings and the limits should be set to manufacturer’s specifications.
Connected in a string, all cells receive the same charge current and controlling individual cell voltages as each reaches full capacity is almost impossible.
A voltage peak constitutes an overcharge, causing hydrogen evolution, while the valley induces a brief discharge that creates a starved state resulting in electrolyte depletion. The results are inconclusive and manufacturers as well as service technicians are divided on the benefit. Another method is the hysteresis charge that disconnects the float current when the battery goes to standby mode.
A low voltage suggests a partial charge due to long storage or a high self-discharge caused by a micro-short. Battery University monitors the comments and understands the importance of expressing perspectives and opinions in a shared forum. If they discharge too quick during use only, it sounds like they are too small a capacity for the job.
If the current I am taking is constant is imposible to do this, because my charger will never be able to charge the battery?
Can I use one charger of 1000 mAh output to charge all 3 batteries in parallel and then keep them on a maintenance charge till neded?  Or will I need to charge them one at a time.
I am not sure what is really you question is, but you can’t change a 12v using 24v power supply. I set out to test them to determine if they are working correctly for a 2 year old battery.
It dropped slowly over the next 16 hours (to about 12V, then fell much more quickly over 8 hours to about 11V.
The easiest circuit requires just 1 electronic component which is a 7807 regulator (7 volt regulator). Since you have a 500mA charging current, you can’t continually use more than 500ma for 13 hours.
To simplify what I have said above, the answer to your question is yes, but if you continually use more power than you have provided from the charger, then the battery will eventually drained.
Particularly How much they are applying the Excess percentage to the Practical Applications. Is it Possible to find out the Value of S.G with Voltage before Charging what will be the Values if them corresponding to our Charging Current with duration. He used manganese-dioxide powder as the positive electrode instead of copper; he kept the zinc. During the 1970's, battery technology began increasing rapidly, with new batteries and new ways of making the used batteries occurring regularly. Primary batteries are those batteries that are used only once and then discarded; they cannot be recharged.
The electrolyte is potassium hydroxide, and the zinc and potassium hydroxide are combined in a gel.
When the battery is connected to a load, the Lead combines with the sulfuric acid to create Lead sulfate (PbSO4), and the Lead oxide combines with hydrogen and sulfuric acid to create Lead sulfate and water (H2O).
A spacecraft battery consists of series-connected cells, the number of which depends upon bus voltage requirements and output voltage of the individual cells. Like Ni-Cds, NiMH batteries are available in the standard cylindrical sizes (AA, AAA, etc.). Additional information and a more detailed cutaway view are available by clicking on the image.
Sodium hydroxide types last two to three years making them highly suitable for quartz analog digital watches or digital watches without backlights.
In contrast, zinc air batteries require oxygen from the external atmosphere in order to operate. If you require further details regarding the transaction data, please contact the supplier directly.
The LT8710 is ideal for many types of power supply topologies and can be easily configured for boost, SEPIC, inverting, or flyback configurations. If continually deprived, the battery will eventually lose the ability to accept a full charge and the performance will decrease due to sulfation. A battery with high leakage may never attain this low saturation current, and a plateau timer takes over to end the charge. Chargers exposed to temperature fluctuations include temperature sensors to adjust the charge voltage for optimum charge efficiency. Charging beyond the specified limits turns redundant energy into heat and the battery begins to gas.
Failing to apply the recommended voltage will cause a gradual decrease in capacity due to sulfation. If sulfation could be measured and the right amount of pulsing applied, then the remedy could be beneficial; however giving a cure without knowing the underlying side effects can be harmful to the battery. Using OCV to estimate state-of-charge works best when the battery has rested for a few hours, because a charge or discharge agitates the battery and distorts the voltage.


Battery users have found that a pack arriving at a lower than specified voltage has a higher failure rate than those with higher voltages. A naked plate will sustain irreversible damage through oxidation, leading to reduced capacity and lower performance.
Do not fill to the correct level before charging as this could cause an overflow during charging. However, all communication must be done with the use of appropriate language and the avoidance of spam and discrimination. We recommend posting your question in the comment sections for the Battery University Group (BUG) to share. How there are calculating the Capacity (Ah) in Theoretical Manner and how they are applying the Practical Ah to the battery. They have the dual advantages of having both a higher initial voltage and longer life than secondary batteries of the same size. The manganese-dioxide cathode is contained between the can wall and the separator, which keeps the cathode and anode from direct contact. As the battery discharges, the Lead sulfate builds up on the electrodes, and the water builds up in the sulfuric acid solution. A nickel cadmium battery converts chemical energy to electrical energy upon discharge and converts electrical energy back to chemical energy upon recharge. They differ from Ni-Cds, however, in that they are capable of a higher capacity without developing what is often referred to as the Ni-Cd emory Issue.
The main difference between these two battery types is the substitution of a metal hydride instead of cadmium. Potassium hydroxide types are better for the short bursts of higher current drains that are required from LCD watches with backlights. This saves space as well as eliminates the need for an internal, often toxic, material. The LT8710’s rail-to-rail output current monitor and control allows the part to be configured in current limited applications such as battery charging. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells. A float current that is too high for the faded cell might sulfate the strong neighbor due to undercharge.
Although in-house service can often bring such batteries to full performance, the time and equipment required adds to operational costs. Old batteries loose capacity but yours should be in good condition being only one year old. Little current will take forever to fully charge it up, so you can safely charge it using 10A. The acid started to eat away the zinc rod, while the copper rod captured the energy released from the action. Gassner used zinc to hold all of the components and kept zinc for the negative electrode as well.
Additional information and a more detailed cutaway view are available by clicking on the image. Hearing aids and electronic measuring instruments also use batteries with a potassium hydroxide electrolyte in combination with a special separator to match the application. Cell-balancing devices are available compensate for the differences in voltages caused by cell imbalance. As stated above, a fully charged 6 cell battery shows about 12.65 Volts when fully charged whether it is a small car battery or a massive forklift truck battery. A dead battery in cold will work after it warm up, so be sure to know that Voltage reading is not accurate in winter time. Leclanch put the whole business, or the cell, into a glass jar and invented the first wet battery. While the initial voltage and battery life is less, they have the significant advantage of being reusable. The disadvantage of zinc air batteries is that they must be sealed from the outside atmosphere prior to use in order to prevent the battery from self-discharging.
The combination of sealed construction and Yuasa’s unique electrolyte suspension system allows operation in any orientation, with no loss of performance or fear of electrolyte leakage. Watering systems eliminate low electrolyte levels by automatically adding the right amount of water. Lead acid batteries must always be stored in a fully charged state and be periodically recharged even when not in use. It is best if u built ur own charger, or you really want to get a more expensive smart charger. He also added zinc chloride to the electrolyte, which cut back zinc corrosion when the cell was inactive.
The electrochemical principles that he discovered are still the foundation for the battery industry. On no account should the battery be charged in a sealed container.The heavy duty lead calcium alloy grids provide an extra margin of performance and life in both cyclic and float applications and give unparalleled recovery from deep dischargeCAUTION- Do not Short Circuit- Do not charge in a sealed container- Service life and operational characteristics will be affected by temperature- AC Ripple reduces service life. Now, for the first time a dry cell battery was a neat, tightly sealed package, almost ready for mass production.
As the battery is discharged, the process is reversed, as shown in the following formula. Batteries were first mass-produced in 1890 by the National Carbon Company at their plant in Cleveland, Ohio.
