How Often Should I Change the Battery on My Generator?

You should change the battery on your generator every three years. As long as your generator’s battery is properly charged and maintained, it can last you up to four years. However, it’s safer to replace the battery sooner rather than later so that you don’t find yourself stuck in the dark of a power outage.

What Does Your Battery Do?

The battery on your generator is designed to provide power to start your generator’s engine when an outage occurs. A failing battery is one of the most common reasons for a generator failure, so it’s a smart move to change it before it dies out on its own.

It’s easy to forget to replace the batteries on any device, especially your generator. You might want to make a note of when you put a new battery in, and maybe coordinate that change with other maintenance tasks so you remember.
