Why do car batteries die?

We’ve all been there. You’re getting ready to head to work or go on a road trip, and you turn the key in the ignition, only to be greeted by a sickening click-click-click. Your battery is dead, and now you’re stuck. But why do batteries die in the first place? Let’s take a look at some of the most common reasons.

One of the most common reasons for a dead battery is simply aging. Batteries have a lifespan of 2-5 years, and after that, they start to lose their ability to hold a charge. If your battery is starting to get up there in age, it might be time for a replacement.

Another reason batteries die is due to extreme temperatures. Hot weather can cause the water in the battery to evaporate, which leads to corrosion and damage. On the other hand, cold weather can make it tough for the battery to turn over the engine. If you live in an area with extreme temperatures, be sure to check your battery regularly and replace it as needed.

Finally, if you don’t drive your car often enough, that can also lead to a dead battery. Batteries need to be regularly used in order to stay charged. So if you only use your car for short trips around town or don’t drive it at all for extended periods of time, that can contribute to a dead battery.

There are a number of factors that can contribute to a dead car battery, but some of the most common include age, extreme temperatures, and infrequent use. If you think your battery might be going bad, be sure to have it checked out by a mechanic before it leaves you stranded.
