          Easy Setup
          While it is a bit on the heavy side, it was quite easy to setup.

          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.

          Maintenance free battery-powered is the best idea ever. I have been using the watchdog sump pump for seven years already. Happy with the product.
