Overcharging Your Batteries Is Too Much Of A Good Thing
One of the most common problems we see in the shop is batteries being overcharged. Keeping your batteries charged is important, but there can be too much of a good thing. Overcharging your battery is risky and can cause it do “boil dry” and stop working. Learning how to take care of your batteries is important, especially if you have seasonal use vehicles or are often away on vacation.
There are five top reasons batteries die and one of them is because of overcharging. An overcharged battery is often described as “boiled”. It shouldn’t be a surprise to learn that a boiled battery is no good.
Why Is Overcharging Your Battery Called “Boiling”?
Your battery creates electricity and feeds it to your car to get it running. This process creates heat. In many ways, it works like a kettle. Electricity is applied to the water. This causes it to heat up and some of the liquid evaporates. The difference being that, in a car battery, the liquid is a carefully balanced solution made of electrolytes and distilled water. If the battery is charged continuously for too long, the heat will cause some of the water to evaporate from the solution that fills your battery. When too much of this solution evaporates and only the electrolyte is left, your battery has “boiled dry” and may not work properly or at all.
Avoid An Overcharged Battery With Proper Maintenance
The best way to keep your battery running is to connect it to a charger once a month until it is fully charged. No more. No less.
