Re: Signs of house battery going bad
Jeffery, five years is fairly reasonable. To see how good it is, cover the solar panels, give the battery a good days worth of hard charge, then let it sit with no charge and no load on it at all (nothing on in the van) for a day or two. Also make sure all the battery connections are sound. If the voltage drops to 12.5, the battery is about half way gone, but if it drops to 12.2 it's history. 12.8 indicates a battery with most of its life left and as the resting voltage lowers (while testing like stated above) it's basically like the battery is getting smaller (the amp hours drop) and won't power things as long. Colder weather also has more of an effect on it as well. You might be able to equalize the battery to gain back some of its life but I'd check with the manufacture before doing that. There are some other ways to bring back life to some AGM's but it can be risky (fire /explosion wise)
