You have a choice to make when it comes time for adding an extra level of protection against flooding and power outages: do you want backup or not?

A battery-powered sump pump will ensure peace-of mind during those heavy rainstorms or prolonged periods without electricity.

If you live in an area prone to flash floods and storm, it's important that your pump be protected by a high-quality battery backup.

A battery backup system is a great way to protect your house in case of an emergency. If you lose power during heavy thunderstorms, then there's no need for worry because this device will kick on and ensure that everything stays dry!

It consists primarily out two parts: A large nickel Cadmium battery (typically 8-20 volts) which stores energy when it doesn't have access to electricity from the grid; as well as secondary pump called "backup" whose sole purpose would be kicking into gear if needed.

Note that there are some homeowners insurance policies that offer coverage for sump pump issues but oftentimes, they require that the sump pump be equipped with a backup battery.

Just like any other appliance or tool for your home, there are advantages and disadvantages to a battery backup sump pump.

How To Tell If Sump Pump Has A Battery Backup

The normal setup for a sump pump with a battery backup has an external battery to the sump pump. So, if you see an additional unit attached to your sump pump, the chances are that it's the backup battery.

Can you add a battery backup to an existing sump pump?

Adding a battery back up to an existing sump pump installation is possible, but the process can be tricky. A professional will know how best to install it so that your house's water protection lasts as long as needed!

How Does A Battery Backup Sump Pump Work?

The battery-powered sump pump is a great way to protect your home from flooding. It works the same way a standard sump pump works - by directing water out of and away from the house with pipes, preventing it running straight back into our basements where we can damage more space!

The difference between these two types of sump pumps is the power source. A standard sump pump uses electricity to work whereas the battery powered one relies on the battery for it to work.

This means then that it's important to make sure that the battery in your sump pump is charged fully at all times.

How Many Hours Does A Sump Pump Battery Backup Last?

Fully-charged sump pump backup batteries will last 5-7 hours of continuous pumping and 1 to 3 days if you don't use your sump pump continuously.

Beware though that these estimates are for brand new batteries. The older a backup battery is, the less efficient it will work. So, you may end up with a battery that works only for 2 hours.

Once the battery powers down, it can take up to 30 minutes to recharge.

How Often Should I Replace The Sump Pump Backup Battery?

That is why the recommendation is to replace your sump pump's backup battery every 5 years.

This will save you in the long run.
