There's no doubt that winter is tough on batteries. The sound of a struggling motor is a common occurrence when temperatures are cold outside. At the other end of the spectrum, though, hot summer weather can prove just as disastrous for the longevity of batteries. To better understand why, we at Mercedes-Benz of Tacoma offer these insights into how batteries work.

The main reason why summer weather shortens the life of a battery is because hot weather increases the capacity of a battery. While this increase in capacity is good in very limited circumstances, the problem comes when the alternator charges the battery while the vehicle is running. The alternator will simply charge the battery to its current capacity, meaning hot weather will allow a battery to be overcharged. Just as with any other rechargeable battery, overcharging a car battery will result in shortened battery life.

If your battery doesn't seem to be providing the power that it used to, feel free to reach out to our service department today.
