2. Inserting Batteries

Insert 1 to 16 AA or AAA NiMH rechargeable batteries into the individual charging slots. Ensure the positive (+) and negative (-) terminals of the batteries align correctly with the markings in the charger slots. Incorrect insertion can prevent charging or damage the batteries/charger.

Operating Instructions

Charging Process and Indicators

Once batteries are correctly inserted and the charger is powered, the LED indicators around each slot will illuminate to show the charging status:

• Red Light: Indicates that the battery is currently charging. The red light will flash approximately every minute during the charging process.
• Green Light: Indicates that the battery is fully charged. The charger will automatically switch to trickle charge mode to maintain battery capacity.
• Red Flashing Light: Indicates a non-rechargeable or broken battery. Remove such batteries immediately.

Automatic Shut-off

The charger features an automatic shut-off function. Once a battery reaches full charge, the charger will cease active charging for that slot, indicated by a solid green light. This prevents overcharging and helps prolong battery life.

Battery Detection Function

The charger incorporates a battery detection function. It takes approximately 15 seconds to detect the battery type. If a non-rechargeable or faulty battery is inserted, the corresponding red light will flash, indicating a problem. Remove such batteries to prevent potential issues.

Care and Maintenance

Cleaning

To clean the charger, disconnect it from the power outlet and use a soft, dry cloth. Do not use liquid cleaners or abrasive materials. Ensure the charging slots are free of dust and debris.

Storage

Store the charger and batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, it is recommended to store batteries with a partial charge (around 50-70%) to maintain their health.

Battery Longevity

The BONAI NiMH batteries are designed for high performance and durability. They feature advanced low self-discharge technology, retaining approximately 75% of their capacity even after 3 years of non-use. With up to 1200 recharge cycles, these batteries offer a long service life.

Troubleshooting

• No LED light when battery is inserted: Ensure the charger is properly plugged into a live power outlet. Verify that the battery is inserted with correct polarity (+/-). If the issue persists, the battery might be completely drained or faulty.
• Red flashing light: This indicates a non-rechargeable battery, a broken battery, or a battery with incorrect voltage. Remove the battery from the slot. Do not attempt to charge non-rechargeable batteries.
• Batteries not fully charging: Ensure the batteries are NiMH type. Check for proper contact between the battery terminals and charger contacts. If using older batteries, their capacity may have degraded over time.
• Charger feels warm during operation: It is normal for the charger to become slightly warm during charging. The built-in cooling system is designed to manage heat. If the charger becomes excessively hot, disconnect it immediately and contact customer support.
