2. Identify Battery Terminals: Locate the positive (+) and negative (-) terminals on your battery. The positive terminal is usually marked with a plus sign and is larger, while the negative terminal is marked with a minus sign.
3. Connect Red Clamp: Connect the red (+) alligator clamp from the charger to the positive (+) terminal of the battery.
4. Connect Black Clamp: Connect the black (-) alligator clamp from the charger to the negative (-) terminal of the battery.
5. Plug In Charger: Once the clamps are securely attached to the battery terminals, plug the charger's AC power cord into a standard wall outlet.

Warning: Always connect the clamps to the battery before plugging the charger into the power outlet. Disconnect in reverse order: unplug from outlet first, then remove clamps.

5. Operating Instructions

After connecting the charger as described in the Setup section, the device will automatically begin its charging process. The LED indicators provide real-time status updates:

• Power LED (Red): Illuminates when the charger is plugged into an AC outlet and receiving power.
• Charging LED (Orange): Illuminates when the battery is actively being charged. This light will remain on during the charging cycle.
• Full/Standby LED (Green): Illuminates when the battery is fully charged or in maintenance mode. The charger will automatically switch to float/maintenance mode to prevent overcharging and keep the battery at optimal voltage.

You can monitor the battery's charging status by observing these LED indicators. Once the Green LED is lit, the battery is ready for use, or the charger can remain connected for long-term maintenance.

6. Maintenance

The HECHOBO charger is designed to maintain your battery, but proper care of both the charger and the battery is essential for longevity.

Charger Maintenance:

• Keep the charger clean and dry. Store it in a cool, dry place when not in use.
• Inspect cables and clamps regularly for any signs of damage or corrosion. Replace if necessary.
• Do not expose the charger to extreme temperatures or direct sunlight for prolonged periods.

Battery Maintenance:

• Regularly check battery terminals for corrosion and clean them if needed.
• For non-sealed batteries, ensure electrolyte levels are adequate.
• Use the HECHOBO charger to keep infrequently used batteries (e.g., in lawn mowers, motorcycles, ATVs) fully charged during periods of inactivity to prevent sulfation and extend battery life.
