The indicators are nice, except I wish they had picked a different color to show that a "wet cell" battery had been selected. They use a red LED. Red means trouble (normally), so this is a bit misleading. Otherwise the indicator LEDs are nice because they show if you have shore power working, and also the charging status of the batteries. It's nice to know at a glance that your batteries are fully charged.
I will update this review as I get more experience with the charger.
11/10/2011 Update. This charger has been installed for over two years now. It has worked without any issues. This is a good charger. I would recommend it.
12/23/15 Update: This charger is still going strong after 6 years of continuous use. I still recommend it.
I installed this on a cabin cruiser in the summer of '09. The prior charger was the original on a '89 vintage boat. They've come a long way since then. We take the family out and spend the night at the beach or out at anchor. It is imperative that the batteries are in top condition as getting stuck out on the water is not something I want to experience (again).
I've got a dual deep-cycle battery setup, and wanted something to help ensure the batteries would live a long, productive life. I learned the hard way with a prior boat that while the old single stage chargers would indeed charge a battery, they were not good at maintaining a battery and eventually the batteries would fade and have to be replaced (although at some point they'll need replacing regardless, but I'd like that day to be as far off as possible.) For as much as the batteries cost, and the hassle of moving them around, I want a solution that I can plug in and not have to worry about. I also wanted something that maintained each battery separately so that if one had a week cell or something it would not affect the other battery.
Installation was easy. I ended up cutting the plug off the power cord and hard-wiring into a junction box to interface with my boats shore power system. Setup consists of connecting to the batteries and then selecting which type of battery each is so that the charger can use the proper algorithm. Very very simple.
When I arrive at the dock and with the shore power connected I can quickly see the status of the batteries by the color of the individual LED's. The unit is mounted in the engine compartment and I just lift the lid and take a peek.Read more ›
It just works which is why I sometimes just forget about it. It really needs no adjustment once set-up.
This one is one I use to keep my mower & Boat batteries maintained.

Didn't take long to hook up, wire leads to batteries are short unless both of your batteries are setting together! Had to add 10 ft to one set of leads,bet it voids the warranty! Read morePublished on March 5, 2014 by Larry J
