APC UPS RBC1 Replacement battery
2 x VISION CP645 F2 terminal
For Back-UPS BK200B and other.
VISION CP645, 6V 4.5Ah
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 oneway 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.
