This will allow you to take longer power hits with no concern, and keep your batteries virtually unaffected by smaller hits. I'd suggest getting a better UPS with monitoring capabilities, and a larger capacity as well.

AGMs will recover better from the deeper DOD than flooded batteries also of course. 50, 100 bucks in new batteries is far less than the cost of the fish or plants and the time it takes to grow them. If it's keeping plants or fish alive, I say run it until it dies. Add water to the sump until the backup pump runs, then measure the voltage. If you want to perform the second test but no water is running into the sump, again, unplug the battery charger and the primary pump. The actual depth of discharge (DOD) where this tradeoff of DOD vs damage is somewhat of a personal decision, since deep cycle batteries are designed for this purpose, but really, batteries are relatively cheap. If it is less than 11.6 volts, consider replacing the battery. But what do you do when it won’t stop beeping Whether it be low water levels or that it lost power, let’s explore what it means when your sump pump battery is beeping. Since you are talking about a battery backup, I will presume that you are using AGM sealed lead/acid batteries and they can be discharged deeper before the damage occurs (most will say around 80%). February 26th, 2022 6:57 AM Share A sump pump is a critical piece of equipment in a home that is subject to regular flooding. A normal flooded battery should not be discharged beyond about 50% or it can sustain permanent capacity damage. r/DIY now has a Discord channel!
