PumpSpy 12 VDC 40 Ah Deep Cycle AGM Battery

Reviews said it could be used with my Watch Dog sump pump system but that wasn’t the case because I couldn’t override the low water beeping alert despite everyone’s suggestions. Stick with the same battery your system came with. Fortunately was able to sell the battery to a friend.

Using it on my Watchdog pump..Works well so far..Hope to get long service out of an AMG battery

Overall, I am happy with the product I purchased. My only complaint was that the package was all beat up and falling apart when it arrived on my doorstep. The packaging and handling should be better.

I've been using this for less than 4 months as back-up power for a sump pump. The power never went off so it's never really been "used" and the converter is saying that the battery needs to be replaced.

Works
