These sites typically require diesel generators to support the batteries, and due to the lengthy charge time necessary for lead acid batteries, the generators are often forced to operate for extended periods.
ENGADGET: A123 Systems' new lithium ion tech keeps EV batteries cool, your wallet in check
Its original nickel-metal-hydride battery packs have been replaced with lead acid batteries to extend the distance the car can travel on electricity.
Chip developer Qualcomm says plug-in charging is too "cumbersome" and its tech could lead to batteries being topped up while cars are being driven.

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.
In higher-temperature climates, for example, the cost of installing and running the air conditioning necessary to properly cool the lead acid batteries can represent up to 50 percent of the total power consumed at each cell tower site.

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.

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.
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.
This is a particular mystery because tin, which shares many of the features of lead, makes lousy batteries.
Secker believes the fastest growing battery sector will be electric vehicles but at the moment laptops, cell phones and rechargeable batteries still lead the pack.
FORBES: Canada Lithium on Target For 2013 Production; To Be First Canadian Lithium Producer
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.
FORBES: Johnson Controls Earnings: Weak Europe Could Offset Gains From Asia
This design, combined with flexible, thin-film batteries, could lead to a flat device that is far less obtrusive than a lumpy generator.
We've got to push hard this year so that we are once again the leaders in solar and wind and high-efficiency batteries that can lead to the plug-in automobiles of the future.
The floral patterns could lead to longer-lived supercapacitors and lithium-ion batteries, and the germanium sulfide is both cheap and clean enough that it could lead to very efficient solar cells that are more environmentally responsible.
Those cars need a lot more batteries than hybrids, and lead is, well, heavy as lead.
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.
BBC: US manned deep-submersible Alvin prepares to resume work
For, according to Dr Pyykko's calculations, relativity explains why tin batteries do not work, but lead ones do.
Lithium batteries are much more likely to experience uncontrolled high temperatures that can lead to fires if they are damaged, exposed to excessive heat, overcharged or have manufacturing flaws.
The initial impact was weakness, with lead the only base metal finding improved demand, likely supported by the immediate need for batteries.
FORBES: Market Nuggets: Record Set Monday For Open Interest In Nymex Platinum Options
Alex Molinaroli, president of Johnson Controls's battery division, said Shanghai authorities have indicated they won't permit processing lead there but may allow the company to perform late stage activity, such as charging batteries for the first time.
Hard to fathom, but he claims he kept 2, 000 tons of phones, batteries, accessories, pagers, cases, chargers and cords--containing arsenic, lead and cadmium--out of landfills last year.
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.
