How Summer Is Destroying Your Vehicle’s Battery

Many folks worry about their batteries failing in the winter, but intense heat can be just as much an issue as the bitter cold.

As the temperature outside your vehicle increases, so does the temperature under the hood; during an average 32 degree day, temperatures in your vehicle can actually exceed over 60 degrees! At this level, battery fluids begin to evaporate which can lead to structure damage, corrosion and the breakdown of key components like the charging system. Once your charging system becomes compromised, your battery can begin to overcharge, which is where things really start to go wrong.

Due to the strain on your vehicle components being typically higher in the summer due to frequent A/C use and higher fan speeds, a faulty battery can quickly begin to overcharge, resulting in the active materials in the plates shedding and twisting due to heat. As this happens, motorists will often notice a build-up of corrosion on their terminals and cables due to gassing, eventually leading to a complete battery failure and need for replacement.

According to 2010’s Battery Council International report titled Failure Modes of Batteries Removed from Service, an average temperature increase of 12 degrees Celsius reduced battery life by an average of 1 year!

Batteries don’t last forever, but keeping your vehicle as cool as possible is a great way to extend their lifespan. If you can’t park in a garage, consider a carport or car canopy. Window covers are a great way to keep the heat from building up inside your cabin, too.
