What the charging LED lights mean on a BLi-X battery charger?

The LED indicators on your BLi-X battery charger provide important information about charging status and potential issues.

Here is what to look for:

Flashing green LED: Battery temperature out of range

If the green LED on your BLi-X battery charger is blinking, your battery is too hot or too cold to begin charging.

Solution:

• Leave the battery in the charger. Charging will begin automatically when the battery reaches a safe temperature.
• Make sure you are charging the battery in an area between 5°C (41°F) and 40°C (104°F).
• The battery itself will not begin charging if its internal temperature is below 5°C (41°F) or above 50°C (122°F).
• Tip: For best results, store and charge your battery at room temperature in a dry, indoor space.
