Every year I make sure to exercise my Boss 3100 battery back up sump pump that I had installed in 2017. Yesterday I let it run on battery all day as the pit was filling with the melting snow, at the end of the afternoon the battery still had 62% capacity remaining. I was very pleasantly surprised with the performance of the 4 year old battery! I have been extremely happy with my Zoeller primary pump & Boss 3100 back up combo, they have provided me with 4 years of trouble free performace.
