Battery Activation: For every installed battery, the D4 will activate the battery by charging it for six seconds at a low current. If zero voltage is detected, all three yellow power indicators will blink quickly. If activation fails the first time, please remove and reinstall the battery once again and activate for the second time. Note: The D4 is not recommended for use with over-discharged (zero volt) UNPROTECTED Li-ion batteries. Li-ion batteries without a protection circuit can potentially cause a fire or explosion.
