Valve control sealed battery is the key of special seal, such as battery leakage, not with the communications room to live in the same room must be replaced.
Phenomenon: white crystal a pole around, obviously black corrosion sulfuric acid droplets. B such as the battery lying on the ground with acid liquid corrosion of the white powder. The C pole copper core green, spiral sleeve drops obviously; or between the tank cover drops obviously.
Reason: a some battery screw loose, sealing ring pressure to reduce lead to leakage. B sealant Aging leads to seal cracks. C battery seriously had pass charge, different types of battery cell compatibility, gas recombination efficiency difference. D with acid acid spills, leakage caused by false.
Measures: A on battery leakage may be false for the late wipe, the effect of B on the screw sleeve leakage battery reinforcement, continue to observe the improvement of battery sealing structure c
