Scotty Hutto Posted December 20, 2019 Share Posted December 20, 2019 Hey Gang, I’m trying to figure out if I need to replace my batteries... I’ve tested battery voltages, both with load and no-load (I have a good battery tester), and for specific gravity. The batteries are Interstate Deep Cycle Extreme GC2-XHD-UT 232 Ah, installed December 2015. Two of the batteries test perfectly fine in all respects. One battery tests “weak” for voltage under load (5.4v). No load voltage and specific gravity are fine. One battery tests “weak” for voltage under load (5.8v) and has lower specific gravity in one cell (1.210 - 1.275) We rarely boondock. Should I try to stretch these a little longer until they go from “weak” to “fail”, or is the wise thing to go ahead and replace. If I replace now I can save about $80 on the batteries I’ve selected due to a current sale. Advice? Thanks, Scotty Link to comment Share on other sites More sharing options...
