I have a PHCC 2400 battery backup sump pump. It started beeping today and the controller light indicated that the battery terminals were corroded or that the battery was bad.
I opened up the case and checked the terminals, no corrosion. I pulled the plug on the controller (charger) and tested the battery and it read 12VDC. The manufacturer sells two different replacement batteries. One that you fill yourself and one that is pre-filled and sealed.
Can I use something like this instead?
Note: I found the actual product on ebay which lists it at 12V, 90A max. So it would seem the universal battery I found would fit the specs.
