Having a backup battery powered sump pump has saved me more than once. When the power goes out and the water comes in one of these handy sump pumps will leave you resting easy.

Choosing the right battery backup sump pump is important so that you can protect your basement from flooding when you are dealing with a lot of rain. 

I find that there are three main things that you need to consider when looking for a new battery backup sump pump: the type, the switches, and the technology. 

There are two batteries that you can choose from when shopping: the AC/DC battery and the DC battery. 

AC/DC batteries can work on both AC and DC currents. 

This means that they will use DC when the power is out and when the electricity is on they will use alternating current. 

This keeps the battery from being depleted when not needed. 

DC batteries, on the other hand, will only use battery power when the pump needs to run.

Make sure that you also take into consideration whether you want a traditional wet cell battery that you have to maintain on a regular basis or an AGM sealed battery for less required maintenance.

You also need to consider the switches of your sump pump. 

By opting for a backup battery sump pump with a float switch, you will have additional protection against flooding in your basement.

Finally, consider the innovative technology that your new backup battery sump pump comes with. 

This is where you can really decide for yourself what type of technology you want to include on your battery backup sump pump. 

Features, such as text alerts, when there are problems or an LCD screen to check the condition of your battery are all technology options to consider. 

Benefits of a Battery Backup Sump Pump

You’ll enjoy a few advantages when you install a new battery backup sump pump at your home. 

Not only are these units incredibly powerful, but many of them offer impressive pumping power. 

Which means that your basement will be cleared of water and you can stress just a little bit less.

Additionally, one reason why I love these sump pumps is because they install really quickly and easily. 

Once you have your unit mounted and connected to your primary sump pump, installation is fast. 

This is partly because they will usually use the same discharge pipe as your main sump pump. 

I love that these units are fully automatic, making them ideal for homeowners who aren’t home a lot. 

You won’t have to manually turn your battery backup sump pump on. 

This feature is also great for vacation or rental properties. 

As long as your unit is installed correctly, you won’t have to worry about charging the battery either. 

Additionally, the inverter will turn on when your power goes off, leaving you upstairs staying warm and dry, not rushing to the basement to turn on your system. 

Finally, I think that most homeowners love the increased peace of mind that they enjoy when they install a new battery backup sump pump. 

Knowing that your home will be protected in case of a flood due to heavy rains or a lot of melting snow will help you to relax and not worry about the condition or the function of your primary sump pump.


Of course, there are a few things that you need to take into consideration when choosing a new battery backup sump pump. 

Keep in mind that your terminals will need to be cleaned twice a year to ensure that your battery will work the way that you need it to. 

You will also need to replace your battery on a regular basis to ensure that it can hold a charge and power your sump pump. 

I like to test my battery every six months and replace when necessary.

Additionally, depending on the type of battery that you use, you will need to add water to the battery every few months, though I prefer an AGM battery. 

I also recommend to homeowners that they check the condition and the level of their battery on a regular basis so that they are not caught unaware with a battery that won’t power their sump pump. 

Do this during your six month battery test.

This is one reason why opting for a backup battery sump pump with an LCD screen is such a great idea, as you won’t have to worry about how to check the condition of your battery and you can simply read the information on the screen. 

Many battery backup sump pumps have powerful and long-lasting alarms that will sound when there is a problem with your battery or your system. 

You need to take into consideration whether you will be home on a regular basis to deal with the alarm when it goes off.
