Guest Bluewater Cruising Series Battery Chargers

Guest Bluewater Series Cruising Chargers safely "smart" charge marine flooded, gel and AGM batteries, extending usable battery life. These chargers feature "SmartLeg" technology that enables individual charging to each battery while eliminating the threat of overcharging. The result is a safe charge every time, protecting against costly battery deterioration.

These chargers not only charge your batteries, they also can provide a 12 volt power supply to run any direct current (DC) accessories while the boat is docked. Guest chargers are made to withstand moisture, battery gases, and vibration. They are ignition, reverse polarity, and short circuit protected. The Maintenance Mode provides protection for your batteries during the Winter storage months. Guest Bluewater Cruising Chargers come in three available amperages.

      Comments about Guest Bluewater Cruising Series Battery Chargers:

      The charger installed easily and is quiet. I was little disaoppointed as thought the charger had built in circuit breakers. It does not and a 15A fuse is needed on each positive leg. The description also indicates there are DC cables for auxillary use. There are not. According to the manual that came with the charger there are 4 variations of 2621A. The one here is apparently 2621A-OEM which does not have these features. All in all a good charger for the money and charges both lead and AGM batteries wihtout having to set anything.
