Gel Cell Batteries Safety
Gel cell batteries provide advantages over lead-acid wet cell batteries, but there are also safety hazards associated with them.
Differences Between "Wet" and "Gel" Cell Batteries
Lead-acid batteries are all similar; lead plates are connected in cells and surrounded by an acid that creates a chemical reaction resulting in an electrical voltage. Water must be added periodically to maintain a liquid level in a wet cell. A gel cell also contains acid, but it has been gelled and sealed in the battery case. No maintenance is needed. The battery may be placed in different positions without fear of leakage.
Charging Safety for Gel Batteries
If too high a charging voltage is applied, the case can be over-pressurized and can explode. A charger designed for gel batteries should always be used.
Other Safety Considerations
Never allow any open flames or smoking when charging gel cell batteries. Never allow the positive and negative terminals of the battery to be directly connected, for example from a dropped tool. The direct connection can result in an explosion. Replace leaking batteries. Protect your skin and eyes from acid.
