Battery Type Selection

IMPORTANT NOTICE: Lead-Acid / Gel Battery Selector

The ProSport battery charger is factory set for lead-acid batteries. It can be reset for gel batteries by using the one-time gel selector. This selector is simply a jumper on the side of the charger where the DC cables are located. By cutting and removing the jumper the ProSport will be set for gel batteries. After cutting the jumper fill the dimpled area with a marine grade silicon sealant. Please contact Sterling Power Products if you have any questions regarding the correct battery type setting. This is a one-time selector.

Charging Batteries

The Sterling ProSport series is designed to charge, condition and maintain your batteries. Please follow these steps each time you use your ProSport charger.

1.Open all battery compartments and ventilate for at least 15 minutes before applying AC power to your charger. While charging your batteries make sure to keep your battery compartment open, allowing for free air ventilation.

2.Make sure all DC battery connections are tight and clean. Follow the battery manufacturer’s recommendation for battery cell caps. Loosen caps if applicabel.

3.Connect a heavy duty extension cord to the ProSport charger first. After connecting the extension cord to the charger proceed to plug the extension cord to a nearby RCD-protected AC power outlet.

4.Observe the on-board LED indicators for a solid green and red indication. This will tell you the batteries are in the charging process.

5.Charge your batteries until only the green LED indicator remains on. This indicates that the charging process is completed and your batteries are fully charged and are now being maintained in a gentle float / storage mode. (Recommended while your boat is not in use.) The ProSport can be left on in this mode indefinitely and will never overcharge your batteries.

6.When ready to use your boat, unplug the extension cord from the AC power outlet first, followed by unplugging the charger.
