Trickle charger on portable generator - bad battery?
I have to keep my portable generator on a trickle charger or the battery goes dead. It can take a few weeks, but it is always a problem at the worst time (we lost power for three hours on Christmas Eve and the battery on the generator was dead!).
I hate to pay the expense of running the trickle charger all the time, not to mention the not-so-green aspects of using juice all the time. We've had the generator for two years and this Christmas would have been the first time we used it. Most of the time, it just sits there.
I'm considering a solar powered charger. But before I spring for one, I'm wondering if this is a sign of a bad battery or perhaps some short or load that's draining the battery? Could I simply disconnect the battery to keep it from discharging?
I see solar powered trickle chargers in 1, 1.5, and 5 watt sizes. Which would you buy?
