Review: Great charger - So far this appears to be working great, charging and maintaining my boat batteries Easy to use with clear directions, easy to install
Review: Great Product - I had the original version of this charger in our Crownline for 8 years and loved it. It worked perfectly, and kept the original batteries that came with the boat working great for that entire time. That is, until it got struck by lightning... So I ordered this, updated version of the same charger. It is exactly as nice as the old one with some nice upgrades including the charging gauge and the easier method of selecting the battery chemistry. I was extremely happy with the first one and would still have it if not for our mishap. I expect this one will carry on as the old one did, keeping my original batteries topped up when the boat is sitting.
