As a result, high temperatures occur in the battery, so that the battery life is extended, and the charging process is accelerated. Conditioning charge can extend the life of battery by automatically searching the optimum charging condition for the batteries in every situation. The battery employed in the following conditions repeatedly requires "conditioning charge" to prevent fast wear out. In that case, yellow light lights up.If both the red and green lights are solid then this means the battery is charging. It also means the battery is above 80% charged but it is not fully charged.

If the battery is belowor abovethe ideal operating temperature charging may not start.

Adaptive charging: The charger can perform adaptive charging to extend the battery's lifespan. In certain situations, the charger automatically searches for optimal charging conditions for the battery. The charging process may take longer than usual. When the temperature of the battery is extremely hot, more than approx. 70°C, two charging lights may start flashing red. When the temperature drops to 50°C – 70°C, one charging light will flash red. Leave the battery to stand for a while to cool down before attempting to recharge.
