How to Choose The Perfect Battery Backup Sump Pump for Your Home – The Ultimate Buying Guide

First step is to determine what type of battery you want.

Solar Battery

Many homeowners will install a solar panel outside about several feet from the garage to charge up the backup battery. Although this is not the usual way for a battery to get power, some people find it useful. Therefore, you will need to perform all the modifications yourself.

AGM (Absorbent Glass Mat) Battery

This is the best type of battery for sump pumps that works with the technologically advanced systems. AGM batteries range from the maintenance-free, deep cycle, to wet cell and marine.

  • A maintenance-free battery does not require constant attention and runs longer.
  • Marine batteries need water and constant maintenance but are more reliable.
  • Wet cell batteries are mostly found in the automotive industry to start cars, so you want to avoid them for a sump pump. This battery has sealed and unsealed versions requiring inspection and more prone to damage and explosions.

AGM batteries mostly supply DC currents. Has a lifespan of 7 to 10 years.


Getting a battery backup sump pump made with the right material is very important. Some battery backup sump pumps have a mixture of these materials, so choose wisely. Here is a list of some:

  • Cast iron - The majority of battery backup sump pumps have this material because it is sturdy and heavy-duty. The best in the market. Cast iron runs cooler than the others, perfect for extreme weather conditions. However, they are very heavy
  • Plastic - Although using plastic is cheaper, it is weaker and could crack over time under strenuous circumstances. People normally purchase this type of sump pump if they do not plan to use it often. It is made with this material and normally comes with a long warranty
  • Stainless steel - Battery backup pump is made of stainless steel are a lot stronger and last longer. This material also prevents rusting

Pump Capacity

  • It is best to choose a battery backup sump pump that exceeds 35 to 60 gallons per minute or about 2000 GPH to 3600 GPH


  • Choose one with an alarm so you can stay alert to any problems. Always research important information before buying. If you accidentally get one without an alarm, do not worry because you can always install a new one later.
  • Get one that is compatible with a vertical float switch. An electronic switch with an internal sensor that detects water is best. When the water levels drop that pulls down the lever which switches off the pump. Also, when the water rises in the sump pit, the alarm will sound off.
  • Piggyback prong - If there are one or two cords in the back of the unit you can evaluate them yourself. Test them out for piggyback prong compatibility. A tether float switch will activate the backup sump pump when the float rises, so look for that.
  • The piggyback prong is a great addition because it controls the submersible pumps that do not have an automatic feature to control themselves. Just insert the prong into the power outlet (as long as a three-prong power plug available). Perfect for failed backup sump pump switches. This low-cost alternative is better than replacing the entire sump pump.


  1. How Long Does a Battery Backup Sump Pump Last?

Although the backup duration solely depends on the type used, most battery back-up sump pump lasts for a very long time before they drain.

Some of these batteries run on AC/DC current while some run on a DC current only.

The backup power can go into a reserve mode after an electrical charge, and this enables it to last for a very long time.

  1. How long will the battery backup last when charged for a single time?

Most batteries on the battery backup pump will last depending on the size of the battery and the amps.

There are some batteries with up to 40 amps of power that may push out of water at the rate of 2000 GPH for up to two days or more.

However, other batteries last between 10 to 12 hours depending on the volume of water it needs to pump.

  1. In which case will I need a combination sump pump?

A battery backup sump pump or primary sump pump will equally provide power to keep your basement dry during a power outage.

However, a combination sump pump provides both primary pump and backup-power capacity all in one convenient, easy to use system.

These sump pumps offer the total power protection especially when the flow of floodwater is too much for your main pump to handle.

Combination sump pumps provides high-power capability when either pump fails.

They help prevent water flowing back into the main sump pump, as well as anti-corrosion and extra backup power protection in severe weather conditions.
