Axion Power anticipates weekly shipments of these batteries in 2011 with a total minimum purchase price of $3.5m and a potential maximum purchase price of $8m.

The company said that batteries will be branded by the purchaser, and will not carry an Axion Power identification label.

The flooded lead-acid batteries will be built by Axion Power, with the purchaser carrying the cost of inventory and providing the raw materials required.

The battery order is well suited to production on the newly renovated, and currently under utilized, manufacturing lines at the battery facility in Clover Lane New Castle in the US state of Pennsylvania.
