Watchdog Basement Backup sump Battery Issue

[jayre]

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.

Does the battery come with a warrentee like car battery?

Only for 2 years.

That's where I would start, see if you can find someone to check the battery.

Might check it with a volt meter, I had a charger go bad on mine, battery was ok.
