        Well made easy to install. Everything is pre-terminated so you just loosen the battery lugs attach and your done. I just wish the wires were about 2 feet longer, then it would be perfect.

            My Grady White is left for up to three weeks at a time. The battery will only last two weeks. A maintenance charger is the prefect solution. Ths size and price on this one were right.

              Comments about ProMariner ProSport 1.5 Amp Onboard Battery Maintainer:

              I like the unit, unfortunately the first one had a defective LED indicator. Now that I have the second one, it is working fine. I mounted in my I/O boat for keeping the starting battery in shape over the winter storage. I would like it better if it operated a bit cooler and had a "completed charge" indicator.

                I installed one of these in my boat several years ago and have had no problems with the battery keeping its charge even after over-wintering. It has worked so well on my boat, I have decided to purchase one for each of my personal watercrafts (2).

                        This is a great add on for keeping your battery charged over the winter or if you sometimes you go three weeks in a row without using your boat. Installs in minutes...and all you do is plug it in when you leave your boat. If you've ever killed a battery over winter - this is for you.
