Northern Tool + Equipment, Generators, pressure washers, air compressors, power tools, trailers, heaters, stoves, food processing, go karts, and more! This simple charger is good for 6V lead acid batteries.The main part of the circuit is the LM317 regulator IC that limits the output voltage based on R1 and R2 values.
Note: If you need a more improve charger with current and voltage control, try to modify the automatic 12V charger circuit. Intro: Design of Lead Acid Battery Charger CircuitHere is the circuit diagram of Lead acid battery charger.

Wave of the future: An Intel employee shows of Rezence, a wireless charging technology being championed by Intel which can charge multiple devices at once and works through tables up to 2in thick. Invented as far back as 1859 by Gaston Plante, the lead-acid model is the first battery that could be recharged by running an electrical current back into it.
The interesting thing about lead acid batteries is that the reaction can be reversed by passing a reverse current through it, essentially recharging the battery. Lead acid batteries are still used in cars and motorcycles today but because of the relatively low charge they hold compared to their weight, not to mention the harmful chemicals, lead acid batteries are not practical for mobile devices. Nickel-cadmium (also known as NiCd or NiCad) were the first rechargeable batteries that were used in a variety of devices from remote control cars to cordless phones and early handphones. Invented in 1899 by Waldemar Jungner, the battery uses electrodes made of nickel and cadmium in an alkaline bath of potassium hyrdoxide. Nickel-cadmium has a terminal voltage of about 1.2 volts and a charge cycle of around 2,000, but it came with several disadvantages. Although it is possible to revive a NiCd battery to almost full capacity and voltage by completely discharging and recharging it several times but it was too tedious a process for most users.
Lead acid batteries are still used in cars, motorcycles and uninterruptible power supplies today. Nickel-metal Hydride (NiMH) cells have largely replaced NiCd as the default battery for most electronics devices that use AA- or AAA-sized battery. Invented in 1967, NiMH use a complex alloy of various metals as well as nickel-hydroxide electrodes in an alkaline bath of potassium hydroxide.
Contrary to popular belief, NiMH batteries also suffer from memory effect though not as badly as they only have to be discharged completely once in awhile to avoid the voltage suppression effect. In 2005, Japanese electronics company Sanyo had a big breakthrough with its Eneloop battery, which is an NiMH battery with a very low discharge rate. The Eneloop (and similar batteries) achieves this by having more efficient separators which keep the two electrodes apart to slow down electrical discharge.


In later batteries the company used thinner separators made of more advanced materials to increase the capacity of the battery. Panasonic acquired Sanyo in 2009, and now Eneloop batteries are sold under the Panasonic brand name.
Although research into lithium batteries began as early as 1912, the first rechargeable lithium-ion batteries were only created in 1985 and commercialised in 1991. Lithium-ion batteries use a complex mix of materials – the cathode is made up of lithium molecules trapped within other compounds, while the anode is usually graphite or a mix of carbon and other compounds.
In fact, the chemistry is quite varied, with anodes, cathodes and the electrolyte solutions using a mix of lithium and other chemicals to offer different effects – more charge, more density, more stability or more resistance to overheating.
The lithium polymer variety is the same but the electrolyte is a solid polymer composite with laminated electrodes and separators which allow manufacturers, especially phone makers, to create a flexible battery that can be moulded to conform to the limited interior space of a smartphone. Lithium-ion batteries’ biggest disadvantage is that they can be overcharged which can cause the lithium-ion cells to combust, often with very spectacular (if extremely dangerous) results. In fact, lithium-ion batteries can combust so easily that even short-circuiting them by connecting the two terminals will cause them to catch fire and explode.
Most manufacturers prevent this by making the terminals recessed so it’s impossible for them to short circuit accidentally.
Because of the risk of overheating and possibly fire, lithium-ion battery packs are designed with terminals that are more difficult to accidentally short circuit. The constant demand for more capacity and faster charging has accelerated research into many battery types. Another possible battery technology is the Na-ion which is essentially made up of sodium-ion or salt – it can hold as much charge as lithium batteries but lasts almost twice as long as it can handle 2,000 charge cycles. There are also solid-state batteries currently being researched by scientists at MIT and Samsung, which offer 20% to 30% improvement in power density compared to lithium-ion and can be recharged thousands of times before it degrades. Beyond just battery technology, scientists are also researching more convenient ways to recharge our mobile devices.
One of the technologies that is already available now but that has yet to catch on is wireless charging.
There are essentially two types of wireless charging technologies, namely inductive charging and magnetic resonance charging.
Both technologies use the same principle – electricity flows though a tightly coiled wire which creates an electromagnetic field that transfers voltage to a nearby object.
Magnetic resonance charging, which was demonstrated by Intel for its Rezence wireless charging technology at its annual IDF conference, works even when the charger and the device are separated by several inches, but is not as efficient as inductive charging. Currently there are two competing standards – the Qi standard which is championed by the Wireless Power Consortium, and PMA which is headed by the AirFuel Alliance (which is made up to two formerly competing wireless standards). While everyone is hoping that the two will merge, companies like Samsung have started supporting both wireless standards.


The charger automatically turns the supply off when battery reaches its full charge voltage.
The main advantages of Lead battery is that it will dissipate very little energy, it has very low energy to weight ratio, it can deliver high current and very low cost. We provide various free project circuits, project ideas on electronics, electrical, robotics, solar, sensor based, communication, etc.
With over 5 million products from 10,000+ manufacturers, we offer the largest B2B catalog on the internet (to our knowledge). The battery was toxic (due to cadmium) and suffered from the infamous memory effect (or voltage suppression if you want to get technical) – if a NiCd battery is repeatedly recharged before it was fully depleted, its voltage and capacity will be reduced. The relatively large size and dangerous chemicals used means its of limited use in handheld devices.
The company claimed that the battery could retain up to 70% to 85% of its charge even after a year. Of the two technology, inductive charging method is the more efficient one but only works at very close range, typically less than 1.5in.
It has a led indicator that turns on when the battery is fully charge thus help you when are you going to remove the battery from the charger.
Are you interested to know about how to design this circuit, working and applications in detailed manner? We cater to the needs of all major verticals, small to large businesses, government, education and healthcare markets, as well as consumers. We often have volume discounts, government & education discounts and loyalty discounts. Without Q1, the circuit still works the way it is designed but there is a chance that it will take some time before it stops the charging, thus might damage your battery. We accept purchase orders from government and public education entities, as well as publicly traded corporations. For your transformer, convert it in full bridge type, meaning you need two more diodes (4 pcs of diode D1 in total). It will ensure also that the charger will not turn off unless the battery voltage reaches the full charge state.. What should be the values of R1 & R2 or what are the required adjustments to this circuit in order to charge my battery.
