Watchdog Basement Backup sump Battery Issue
It's about 3yrs old and the following light is on and is beeping:
Terminals corroded or battery defective / Clean terminals or replace battery.
However, I don't see any corrosion and the battery looks very clean. Resetting didn't help and still beeping. I cleaned the terminals anyway and checked the distilled water level. Nothing helped. Manual says battery is good for 5-7yrs.
1) If my battery is weak, is it possible to jump it and charged up stronger?
2) Do you recommend that I replace it with the same model? It costs $125 + $18 for a bag of acid.
