Quick Guide
The Truper PRO 20V Dual Port Charger is designed to charge one or two batteries simultaneously. It features automatic temperature protection and a defective battery detection system. For optimal performance, charge batteries in an ambient temperature between 18°C and 24°C.
Charging Procedure
To charge your batteries, follow these steps:
- Plug the charger into a standard electrical outlet.
- Slide one or two batteries into the charger slots.
- The indicator lights will flash green to indicate that charging is in progress.
- If a battery is depleted due to continuous use or heat, allow it to cool down before attempting to charge it to ensure a full charge.
LED Indicators
The charger uses LED lights to communicate the status of the battery:
- Green flashing: Battery is charging.
- Green solid: Battery is fully charged.
- Red flashing: Battery temperature protection is active (battery is below 0°C or above 45°C).
- Red solid: Battery is defective.
Battery Maintenance and Safety
To ensure the longevity of your batteries and charger, observe the following:
- New Batteries: Charge new or long-stored batteries before first use.
- Storage: If storing for a long period, charge the battery completely.
- Temperature Limits: Do not charge at ambient temperatures below 4.5°C or above 40.5°C.
- Defective Batteries: If the charger detects a defective battery, it will attempt to repair it for approximately 30 minutes (green flashing light). If the light turns solid red after this process, the battery is likely damaged.
- Cleaning: Never use water or chemical products to clean the charger. Use a dry cloth only.
- Safety: Keep metal objects away from the charger cavities to prevent electrical faults. Always disconnect the charger from the power supply when not in use or before cleaning.
Troubleshooting
If the battery does not charge correctly:
- Check the electrical outlet by plugging in another device.
- Disconnect and reconnect the charger to verify it is functioning.
- Inspect the battery for physical damage.
- Ensure the ambient temperature is within the recommended range (18°C - 24°C).
- If the issue persists with a new battery, have the charger tested at an authorized service center.
