Customer called in needing price on sump pump battery replacement. Upon arrival, found alarm to be beeping snd showing bad battery code on panel. Tested battery and battery only reading 2 volts. Battery needs replaced. Customer was wanting pricing on battery only. Does not want system replaced. We would need to start with new battery snd determine if system is still good. Customer has been living in the home for 4 years and the system has been there before he moved in.
