Checks and Preparation
Charging the Battery
Expected time required for charging:
• Approx. 4 hours
Using the GL450 for Charging
The battery pack is charged by mounting it in the GL450, and supplying it with AC power.
(1) Mount the battery pack in the GL450 (see the previous section for the mounting procedure).
(2) Turn on the power to the GL450. (Please see Section 2.7, "Connecting the Power Cable and
Turning on the Power").
(3) The battery charging LED lights.
CHECKPOINT
• If battery charging is attempted immediately after the GL450 has been used continuously, charging
may not be performed. However, charging will start automatically as soon as the GL450 has cooled
down.
Charging temperature: 15 to 35°C
• If input is being made directly from the DC power supply instead of the AC adapter, the DC voltage
must be at least 16V.
