Editor's Notes
May 30, 2019:
The ProMariner ProNautic 1250 makes its way onto the list as a reliable choice when you wish to power 12-volt electronics on your motorized vessel or sailboat. It boasts 12 digitally-controlled, performance-changing profiles that you can set with ease by pressing the arrows on the front panel. It’ll charge, maintain, and re-condition your batteries, and will kick into energy conservation mode when appropriate. Its LED indicators show the service mode as well as any faults currently present. Leaving the list, due to lack of availability, is the Schumacher XCS15 SpeedCharge.
Also retaining a top spot is the Minn Kota Precision, which will help keep you on the water longer, thanks to its aluminum construction that is impervious to the effects of corrosion. This versatile selection lets you select your battery type by bank (it comes in models ranging from one to four banks), including AGM, gel, or flooded lead acid. This ensures a charge that’s optimized for the specific type of battery.
Always be sure to follow the proper guidelines on handling your marine battery safely. These include wearing protective gloves and eyewear so your skin and eyes don’t come in contact with acid, and avoid getting acid on your clothing. Follow all directions and warnings that come with your battery and charger, and also leave the electrical wiring on your boat to an experienced, licensed marine electrician.
