Charging Car Batteries

Even if you take full precautions for prevention, you could not avoid fully draining your battery. You could drain your car battery when you forget to turn off your headlights, your alternator is broken, your battery is old, or your battery's terminals are full of gunk. When your battery is out, you have no choice but to charge it. But before you do, remember these safety precautions when charging car batteries.


Remember that when you're charging car batteries, hydrogen, a highly flammable and even explosive gas, is released from the reaction of the current and the plates that are immersed in sulfuric acid. Do not light anything and avoid creating sparks near a charging battery. You must also keep the batteries well ventilated while charging to disperse the hydrogen gas.

Before charging car batteries, ensure that the water level reached the maximum desired level. Add distilled water into the battery if you notice that the water is lacking even very slightly. A well-watered lead-acid car battery can purge the hydrogen gas more efficiently than those that lack water. The accumulation of hydrogen gas to dangerous level can very well be prevented if your batteries are well watered before charging - or even during regular use for that matter.

Another important point to remember when charging car batteries is to never overcharge it. An automatic charger that stops charging after it has detected the threshold level, though, can help you on this. But if this is not available, make sure that you follow your charger as well as your battery's manual for charging to avoid overcharging your battery. Overcharging your lead-acid battery can not only shorten your battery's life, but it can be a recipe for disaster also.

While your battery is charging, stay away from it as possible. Warn other people, especially the young children, to stay away from the garage because you're charging your car battery. You must also place the charger as far away from the battery as possible. And remember that you must never place you face over your battery in near proximity because there are instances that a cap could blow due to the gas pressure inside it. Wear protective goggles all the time.

While you cannot avoid charging car batteries, you can, however, avoid the accidents that can occur while doing it. Exercise extra precaution all the time to avoid injuries from charging car batteries.
