Valve control sealed battery the key of special , such as battery leakage, with the communications room live in the same must be replaced.
Phenomenon: white crystal a around, obviously black corrosion acid droplets. B such the battery lying on ground with acid liquid of the white powder. C pole copper core , spiral sleeve drops obviously; between the tank cover obviously.
Reason: a some battery loose, sealing ring pressure reduce lead to leakage. sealant Aging leads to cracks. C battery seriously pass charge, different types battery cell compatibility, gas efficiency difference. D with acid spills, leakage caused false.
Measures: A on battery may be false for late wipe, the effect B on the screw leakage battery reinforcement, continue observe the improvement of sealing structure c
