  • TYPES

Irrespective of the above-mentioned batteries reviewed for Sump Pump Batteries, the below-mentioned points must be an explored before making a purchase so that you don’t despair later

Sump pump batteries are available up to 5000 Watts which can generate a peak load in case of power failure. Most Sump Pump used in residential properties has up to 1 HP Power. So a standard 12 V battery is enough to power them up.
In case of limited space in your basement sump, you can go for a pump with battery backup.

3. BATTERY TYPES

AGM (Absorbent Glass Mat) batteries are the most desirable batteries to consider if you’re working with the latest sump pump batteries. Other alternatives like Wet Cell and Marine batteries require a contact handling for checkups and are also prone to exploding. While the AGM batteries are completely maintenance-free and are quite long-lasting without requiring any constant attention.

4. CHARGING

In case of back-to-back outages, these pumps are highly effective but one must pay attention to the voltage to make sure that the battery is charged in time and doesn’t take too long.
