Although batteries may appear to be uncomplicated, they can be one of the most dangerous components to service if care and caution is not used. Follow the precautions listed on the battery and in your owner's manual. Also, the following precautions will help to avoid injuries. Wear eye protection and gloves when servicing or working around the battery. Avoid dropping the battery.
Batteries can be heavy and can cause injuries if dropped.
Avoid tipping the battery because sulfuric acid may spill out and cause burns. Never smoke when servicing your battery, or subject the battery to a spark or open flame. Explosive hydrogen gas is present and can ignite. Remove all jewelry before servicing the battery. A watch or ring touching a battery post may cause an explosive spark or burn.
