The battery in use will release the flammable gas. So battery should be stored at the place with good ventilation and fireproofing measure should be taken.
3.4 High Temperature
Advice
Too high temperature of battery may result in the distortion, damage and electrolyte overflow of battery.
When the battery temperature exceeds 60 0C, it should be checked whether there is electrolyte overflowing;
In case there is electrolyte overflowing, the treatment for acid liquid should be taken in time.
3.5 Acid Liquid
Advice
When there is acid liquid overflowing, the liquid should be absorbed and the acid liquid should be neutralized with alkali in time.
When the leaking battery is moved and taken away, the hidden hazard of the acid liquid should be paid attention to. Once it is found that acid liquid is overflowing, the following substances can be used to neutralize and absorb it:
Sodium bicarbonate (baking soda): NaHCO3
Sodium carbonate (pure caustic soda): Na2CO3
Various antacids should be used depending on the guide of battery supplier.
