I bought this one instead of a "wet cell" battery because I wanted a no-maintenance battery. Who wants to keep checking the battery and adding water? I was able to hook it up to my Basement Watchdog sump pump system (a primary pump with a battery-powered backup pump) with no problem at all. Just make sure you connect the water level sensor to the positive terminal of the battery so the alarm doesn't keep going off.

Happy with the Basement Watchdog big combo
The Basement Watchdog was easy to install. Fitted my 5 gal plastic bucket (12 in opening). Pump worked well but the backup pump not powerful enough to lift 8 ft plus 3 elbows. Changed the 1/3 HP for 1/2 HP which solved the backup test. Used same bucket. Tight but enough space to free the two floats. Resting on small 1 in brick at bottom of sump pit.
The backup battery and monitor is great for diagnostic. Shows when charging etc. No power outage yet but brings peace of mind. Worth the investment.

I have only had 6 months, but it was super easy to install and NO messy battery acid. Easy to use with the Watchdog system. No problem converting it - just wrapped the alarm wire around the bolt in just a few seconds. Super easy. It was well worth extra money being that the other Watchdog battery died after just over 1 year and I had to mess with adding the battery acid. So far, so good.

Good replacement for battery sump pumps
I purchased this to replace the battery in a Wayne backup pump kit. The original battery was larger physically, but had the same capacity. This was an easy swap, as I just had to switch over the ring terminals on the wires and I was done. I wish there was also a higher capacity version available just to have a longer backup runtime. This was one of the more reasonable replacement batteries in terms of price when I purchased it.

AGM Deep Cycle 75 Amp/Hr Maintenance Free Battery for Battery Backup Pumps
PumpSpy's AGM, 12-Volt 75 Ah Sealed DeepPumpSpy's AGM, 12-Volt 75 Ah Sealed Deep Cycle Maintenance Free battery is recommended for use with PumpSpy Sump Pump Monitoring Systems. This battery is compatible with most other battery backup sump pumps and other products requiring a 12-Volt DC deep cycle battery. Completely maintenance free, this sealed battery never requires additional water or dangerous acid. Sealed AGM (Absorbent Glass Mat) batteries avoid issues like spillage that can occur with traditional wet-cell batteries. Sealed AGM batteries do not sulfate or degrade like wet-cell batteries since they are completely sealed. AGM batteries differ from wet cell batteries in that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase surface area enough to hold sufficient electrolyte on the cells for their lifetime. This results in higher efficiency when both discharging and recharging, due to the higher surface area contact between these critical elements. The thermally welded enclosure eliminates leakage and the battery can be used in any orientation.View Full Product Description
