The ProTechOne is a 5 amp onboard battery charger and maintainer from ProMariner, for 12V flooded lead acid and gel batteries. It charges automatically in several stages and has an auto-maintain mode that lowers AC consumption. The case is gasketed and weatherproof, and a push-to-test monitor shows battery status. It is ignition protected and listed to UL 1236, and a waterproof DC fuse protects the DC wiring.
Our take
The ProTechOne's 5 amp output is aimed at charging and maintaining 12V flooded or gel batteries, with an auto-maintain mode that lowers AC use. The gasketed weatherproof housing and ignition protection mean it is built for onboard installation.
From our buying guide
NMMA says charging sources must meet the charging profile the battery maker recommends. A charger's presets are its own maker's, not the battery's, so set it from the battery maker's figures.
Check before you buy:
- It can follow your battery's profile, since not every charger can follow a lithium maker's.
- Its output suits your bank. ProMariner recommends about 10 percent of the batteries' total amp-hour capacity, with one charger output for each battery.
- It suits how you'll use it, since ProMariner says its waterproof chargers are for batteries not in use while charging.
