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. Portable USB Charger is a device that will charge things like Ipods, PDAs, that accepts charge from a USB port. Automatic battery charger automatically starts the charging procedure when battery voltage drops below a certain predefined value and stops after the voltage has risen above the maximum allowed value. Lipoly batteries are great power source for our AEGs, they offer high current capacities and are available in different shapes and sizes that can fit virtually any AEG. New development in AEG electronics protect the battery from going too low by either cutting the power or an audible warning that indicates low battery voltage. The presented battery saver or TL431 LiPo Saver is designed to prevent deep discharge of lithium polymer batteries. Solar panels should be well adapted to the battery to be charged or the battery may be overcharged. Since this is a simple solar battery charger that does not automatically turn off when the battery is full. An LM317T voltage regulator chip that can be used with a suitable resistor to regulate current. Since the MCP73831 charge-management controller includes a pass transistor, current sense and reverse-discharge protection on a single chip, it reduces the number of system components needed for battery-charger designs, which, added Microchip, lowers overall system costs.
As per manufacturer's data sheets, a 12V rechargeable lead-acid battery should be operated within 10.
It is therefore necessary for all concerned to monitor the charge level of their batteries continuously. The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor. With the help of a precise variable voltage supply, the upper and lower voltage levels were set. Here is a lead acid battery charger circuit using IC LM317.The IC here provides the correct charging voltage for the battery. It takes an input voltage from 8 to 16 volts and can run from anything from a 9 volt battery to a car battery. This battery charger charges a NIMH 5-pack battery used in the BiPed robot in less than 1 hour, and charges the 10-pack NiCd used in the Snuf robot in about 30 minutes. The electric model aircraft and car industries have produced a bewildering array of field chargers for NiCd motor battery packs.
This is a charger for lithium ion batteries which takes its power from the USB port of a computer. This instructable will show you how to make your own solar battery charger from very simple components. This is a MAX1811 based USB charger that can handle both Lithium Ion and Lithium Polymer 3.7V battery.
The ASUS Eee is a fantastic ultra-portable notebook with almost everything required for geeks (and nothing that isn’t). Anyway, being so small I thought it would be nice to be able to carry this around in the car. I thought at this stage it would be worth noting that a commercial car charger is now available for less than it cost me to build this from Expansys and is available in most countries (select your location on their site). I’d actually recommend it over the design here is it seems to perform better at lower voltages (that one works down to 10V). I decided to design the charger around the LM2576 “Simple Switcher” IC from National Semiconductor. When the battery voltage is greater than the cutoff voltage +1v, the Green LED will be on solid. The MAX1551 and MAX1555 charge a single-cell 3.7V lithium-ion LiPo battery from both USB and AC adapter sources.
On-chip thermal limiting simplifies PC board layout and allows optimum charging rate without the thermal limits imposed by worst-case battery and input voltage. The MAX1551 and MAX1555 are available in 5-pin thin SOT23 packages and operate over a -40°C to +85°C range. A very interesting and useful design of a multiple nicd & nimh battery charger circuit which can charge many different NiCd and NiMH batteries.
This is a schematic diagram of a full automatic 12v battery charger for charging the batteries of automobiles etc.

Step 2: Mount the transformer and attach the line cordUse screws to mount the transformer on the plywood base. I miss the days when magazines like Popular Mechanics had all sorts of DIY projects for making and repairing just about everything. These batteries are constructed of several single cells connected in series each cell produces approximately 2.1 volts. It runs off a 9-V battery, and through the simple circuit, out comes a regulated 5-V perfect for a USB port.
Setup can't be easier, just connect two alligator clips to battery terminals and plug the device in mains. While saving up for the "Panther" or "Cheetah" SW-COMP, here is a cheap and easy to construct 11.1V lipoly lo-batt indicator. It consists of a TLV3012 comparator with onboard reference, an voltage divider, load resistors, indicator LED and a transistor.
The diode represents the onboard reference in the comparator, eagle didn't have the device in its library. Decreases the cell voltage of a LiPo batteries below 2.4 volts will permanently damage the cell.
If you want to charge batteries with different capacities, then you need to change the solar panels. So we need to maintain the charging current is low enough that will not damage the battery even when they are fully charged. It features adjustable current charging from 15mA up to 500mA for single cell lipo batteries.
Includes integrated pass transistor, current sense and reverse-discharge protection, the MCP73831 charger reduces the number of components needed for battery-charger designs. But, in practice, many of the battery users are unable to do so because of non-availability of reasonably-priced monitoring equipment. It starts charging when the battery voltage drops beyond a preset value, and it stops when an upper preset voltage is attained. The normally connected (NC) lead of the relay isn't joined to the 15-V dc supply, which blocks this voltage from passing to the battery leads.
It uses a high efficiency switching regulator that runs at 85 - 94% efficiency depending on input voltage and load. To prevent overheating of the battery, the charging current is turned off when the slope of the battery-voltage turns from positive into negative. These range from simple 6 or 7 cell chargers consisting of a resistor and mechanical timer, to more complex chargers with peak detection, cycling, and the ability to handle 36 cell packs.
It is taken from my documentation provided with a kit I supply - you should easily be able to source the same components yourself of course. It periodically measures the charge current and battery voltage, and shows them by blinking two LEDs. Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life.
Initially developed for a sailing boat, the target to reach was to control the level of charge and discharge and to protect a 12 volts lead battery connected to a 32 watts solar panel.
With its performance it is very close to the many of the commercial products available on the market. Unfortunately I couldn’t find a car charger available anywhere at the time so I decided to tackle the problem myself.
There isn’t a fixed voltage regulator available for this exact voltage, so the circuit needed to be designed around an adjustable regulator.
There are tons of ICs like this available, many of which are a bit more efficient, however I selected this one because it is readily available and relatively cheap. They operate with no external FETs or diodes, and accept operating input voltages up to 7V. When the MAX1551 and MAX1555 thermal limits are reached, the chargers do not shut down, but progressively reduce charging current. This allows charging from both powered and unpowered USB hubs with no port communication required.
They cannot be used as a direct substitute (even if they look like other AA's) since they run at about 3.6 (or so) volts. You can also change the output current to desired value by changing the value of resistor RX. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

Import charges previously quoted are subject to change if you increase you maximum bid amount. 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. Portable USB chargers will always be handy, lets face it these days every gadget around us has USB charging capabilities. I used the typical circuit from the datasheet and referred to the pin out to see which pin is what. When the battery is full, the regulator adjust its voltage output from 15 volts down to 5 volts automatically terminate the charging process. Building a solar AA battery charger only requires a few components and a simple construction. The circuit idea presented here will fill this void by providing a circuit for monitoring the charge level of lead-acid batteries continuously. This charging circuit is designed based on this fact.The charging current for the battery is controlled by Q1,R1,R4 and R5. High power density, low self-discharge, no memory effect and they can deliver quite an amount of current.
A second termination-criterion of the charging process is provided for safety: the charge time is limited to about 1 hour. I built this circuit into the plug of a VW solar charger panel that is used to prevent a discharge of the battery when a car is not used for some time. You can select between either 100mA and 500mA current charging mode and LED provides the status of the charging. This 'intelligent' charger was designed for high current and rapid charge applications such as cordless power tools and model racing cars.
If you live in New Zealand you can get them from DSE; at the time of writing they are the exclusive supplier.
It also has a lower drop-out voltage (~2V) than many other chips I looked at which is important when powering the device from a car or 12v SLA battery. The charger incorporates an automatic charge cut-off circuit based on cell temperature, and the cells can be left in the charger indefinitely after cut-off. The circuit is good to use as a car battery charger and for charging the batteries of other automobiles etc.

A twelve-volt battery has six single cells in series producing a fully charged output voltage of 12.6 volts.
This comes very very handy when you have a scooter or a real motorcycle that you don't drive during the winter time.
I have built several of these for use as Tx alarm and they do SCREAM especially if you fit twin piezo sounders.
I also used adapter board so that I could prototype the LiPo battery charger on a breadboard.
A single event of overcharge or deep discharge can bring down the charge-holding capacity of a battery by 15 to 20 per cent.
A modern car contains a large amount of electronics, and a quiescent current of 40-50mA (about 1Ah per day!) is considered "normal". I worked out it’s the same cost as importing one once you include all the duties and tax, plus you get the advantage of a proper NZ-style mains charger. It is better to charge a battery with a current ten time smaller then the battery capacity. In that case, the dome light will remain on all night and the battery will be very low in the morning.I made this charger when I ordered some electronic parts and received a 120 to 12 volt AC transformer with center tap. Because we all know what happens to a battery when not used and especially during the winter.
The barrel plug towards the top goes into an LM7805 that can take 7-16V and regulates it down to 5V.
This charger uses the cell manufacturer's recommended charge method, to safely and quickly charge batteries. I suggest you to charge the battery for 15 hours if you select charging current ten times smaller but if you double the charging current then the battery will become charge in 7 hours. Some friends have also borrowed it when their batteries were dead and it worked for them.The center tap allowed the output to be either 6 or 12 volts.
