Guest 2602 Marine Battery Maintainer/Charger (12-Volt, .5-Amps, Single Output)

This is a must, for any battery that is stored for a few weeks or longer.

I used to charge my boat batteries every few weeks during the off-season, and only got 1 or 2 seasons out of them. Now I leave this charger on them all winter, and I already got 3 seasons out of the same type of batteries. Great product for the price.

This is a very simple, 'hook-it-up and forget-about-it' product. This is the second 2602 I've purchased in less than a year. The first I had to switch between two marine batteries every month or so, but both still remained fully charged. (Now I can keep one on each battery during the winter.) Our boat started right up this spring. I highly recommend this product for maintaining a charge.

I have 2 of these. One on my generator and one for my tractor. Keeps the batteries charged when they are not used for a long time.Works great.
