Fully Automatic Battery Maintenance

The ProMariner ProSport 1.5 is designed to maintain compatible 12V batteries through precise voltage regulation.

Once properly connected to a battery and an appropriate AC power source, the maintainer automatically regulates its output to support battery maintenance.

This helps compensate for normal battery self-discharge during storage and reduces the need for periodic manual charging.

Unlike a higher-output marine battery charger intended for faster recharging, the ProSport 1.5 is primarily designed for maintaining battery charge over time.

Precise Voltage Regulation

The ProSport 1.5 features a precision-regulated charging system with a listed 13.4V DC finish voltage.

Its field-adjustable voltage setting allows the maintenance voltage to be configured for compatible battery requirements, including certain GEL battery applications.

Always follow the battery manufacturer's voltage recommendations and ProMariner's adjustment instructions before changing the factory setting.

Built-In Electrical Protection

The ProSport 1.5 includes several protection features designed to support reliable battery maintenance.

These include:

• Reverse-polarity protection
• Over-temperature protection
• Short-circuit protection
• Ignition protection
• Automatic current limiting

The maintainer is also designed to prevent reverse battery drain when AC power is disconnected or unavailable.

LED Operation Indicator

An integrated LED provides a convenient visual indication of proper operation and current limiting.

This helps users confirm that the maintainer is operating without requiring constant manual testing.

Refer to the ProMariner owner's manual for the exact LED indications and troubleshooting procedures.

Convenient Portable Design

The ProMariner ProSport 1.5 Portable Battery Maintainer includes mounting ears, an AC power cord, and 5-foot DC output wires with alligator clips.

The alligator clips provide a convenient way to connect the maintainer to compatible battery terminals.

Its portable design makes it practical for seasonal battery maintenance and applications where a permanently installed multi-bank onboard charger is unnecessary.

Always use the maintainer in an appropriate location and follow the manufacturer's instructions for ventilation, electrical connections, and mounting.
