CP260
2V 6Ah(20hr)
The rechargeable batteries are lead-lead dioxide systems. The dilute sulfuric acid electrolyte is
absorbed by separators and plates and thus immobilized. Should the battery be accidentally
overcharged producing hydrogen and oxygen, special one-way valves allow the gases to escape
thus avoiding excessive pressure build-up. Otherwise, the battery is completely sealed and is,
therefore, maintenance-free, leak proof and usable in any position.
