Battery Tender Plus... Some Motorcycle shop on the net sells them for

on as needed.

I keep mine hooked up to my motorcycle 24/7 and batteries tend to last
years.


Anybody have experience with the Harbor Freight equivalent of this
device? They go on sale for $5-$6 occasionally.

I have one, and use it quite a bit, but I don't really trust it.
I have no way of verifying how well it works, compared to the Solar
brand that I have. I also have a 2.5-amp model from HF that cost about
$12 IIRC. I give that one a bit more credibility, but I won't go off and
leave it running for months like I do the Solar.
I have a couple of big gel-cells that I'm pretty particular about.
