Personal research opinion is that the lead-carbon battery is one made by Axion Power (AXPW), called the PbC. The PbC has a carbon based electrode, which allows fast charge acceptance and discharge. In addition it has a long life cycle because unlike normal lead acid batteries, the carbon electrode doesn't sulfate. Thus, the PbC is ideal for hybrid and storage applications. This is a first real alternative to lithium based batteries, which has high cost and safety issues. www.axionpower.com
