The relativistic simulations predicted the voltages measured in real lead-acid batteries with great precision.
Dr Pyykko and his colleagues made two versions of a computer model of how lead-acid batteries work.
Motive power products include lead-acid batteries and chargers used primarily for lift trucks.
A123 develops lithium-ion batteries, which can hold a lot more energy than the lead-acid batteries found in most cars today.

Built of plastic to save weight, it was more akin to a scooter than to a bicycle, and it ran on a pair of lead-acid batteries, similar to those under the hood of a car.
Ian Clifford, the chief executive of the Zenn Motor Company in Toronto, has done a deal with EEStor to replace the lead-acid batteries in the small, low-speed electric cars that his firm sells for urban use.
So right now we're looking to move from lead-acid to lithium-ion batteries and we're working with the US Navy on a test programme that would allow us to do that.

Johnson Controls serves this market by providing a variety of automotive batteries like lead-acid for traditional gasoline-powered vehicles, AGM (Absorbent Glass Mat) for start-stop vehicles and Li-ion for hybrid and electric vehicles.

Its original nickel-metal-hydride battery packs have been replaced with lead acid batteries to extend the distance the car can travel on electricity.
This would eliminate what has historically been the only performance advantage of lead acid in starter battery applications, and is expected to considerably increase the value proposition of A123's Engine Start battery as a lighter-weight, longer-lasting alternative to absorbent glass mat (AGM) and other lead acid batteries.
ENGADGET: A123 Systems' new lithium ion tech keeps EV batteries cool, your wallet in check
Atraverda Ltd - The Abertillery-based company has developed a lighter ceramic material to replace the traditional heavier lead components in lead acid batteries making them lighter and greener.
On that crucial dimension, if lithium-ion batteries are a 3, the next best technology, NiMH is a 2, and a lead acid battery, like the one you use in your car, gets a 1.
