I've been through three hours meters so far on my little backup generator and the weak link seems to be the built-in, non-replaceable batteries: Bad Idea in something whose primary job is to stand in wait...
Has anybody found something simple that either uses a replaceable battery or gets it's power from the generator?
Nice-To-Have would be the ability to be preset with my current running total of hours.... but that' just a nice-to-have and not a "Must".
I would think something in-line with the AC that just keeps ticking as long as there is AC present.... but I can't find anything like that.
