How to Choose The Best Battery Backup Sump Pump—Buyer’s Guide

Although we’ve reviewed seven of the best backup sump pumps, making a firm decision may sometimes be difficult especially when you know too very about these products. Since these battery backup pumps are intended to provide an alternative in the event your main pump is unable to accomplish it’s task due to power failure, we’ve added some key factors which we believe will help you make a mature decision when purchasing a new battery backup for sump pump or when replacing an existing unit.

1. The size

By size, we simply mean the size of the sump and that of the existing pump. If the size of the sump is small, then you’ll definitely need to look for a smaller sized backup battery sump pump. In addition to that, you’ll need to think about the configuration of the specific sump pump you’re purchasing. That’s because some models require more space to be configured and installed properly as compared to others.

In case there isn’t enough space in your basement sump, you can opt to choose a model that has the pump and the battery backup put together. At least with such a model, you can squeeze the pump and the battery together to save more on space.

2. Power

In most cases, a backup system can reach 2000 cycles when running on a fully charged 12V/75Amps battery. Depending on the type of setup implemented, a backup battery can run for approximately 5 to 6 hours without being turned off or for 2 days if it’s designed to automatically turn on only when water is present in the pit.

3. Battery charging

Since these pumps are highly effective when there are back-to-back power outages, you need to pay attention to the voltage to ensure that the battery doesn’t take too long to be recharged. Additionally, you may prefer to invest in a particularly larger battery which will not demand frequent recharging.

Another approach you might consider is installing a solar panel in your garage to charge your backup battery. Although this isn’t the usual way of charging these batteries, it may act as a backup plan when power outage cases are severe.

4. Consider AGM batteries

Absorbent Glass Mat batteries, also referred to as (AGM) batteries are some of the best to consider if you’re working with a technologically advanced sump pump battery. These batteries range anywhere from maintenance-free units, wet cells to marine batteries. Wet cell and marine batteries require frequent checkups and are prone to damage and explosions. On the other hand, maintenance-free batteries are long-lasting and don’t require constant attention thus making them the best for sump pumps.
