What is the meaning of the LED indicators on the optional battery charger?
answer
Each battery holder in the optional charger has an LED charging status indicator. The LED color changes as the battery is charged: Red indicates the battery is charging Green indicates the battery is fully charged Yellow indicates the battery is in a waiting state.  A yellow light may occur because the battery became too warm during the charge cycle.  In this case, the charger will allow the battery to cool off before continuing the charge. A yellow light may also indicate that the charger is alternating charge to each of the two batteries.
