I've got a security system that is giving me a "low battery" alert. I measured the gel-cell battery (unloaded) at 13.64V. The battery leads from alarm are showing 13.75V (110 mV difference). I assume this is sufficient difference to kick off the low-bat warning since the gel-cell hasn't charged up to that. I don't really understand lead-acid battery charging in great detail, though.
I know I'd need to cycle test the battery but is it reasonable to assume that the battery is going bad? It is only 5 years old. The environment is a heated basement and it's done maybe 5 full cycles in its life (though none recently). It seems like it should give me longer life than that.
should I be looking elsewhere for a problem? I'll replace it since that's the cheapest option but it does seem premature.
