Replace Battery 3.8

KDC comes with a rechargeable, Lithium-polymer battery. The battery is recharged from

any USB port or KDC charging cradle and can be recharged about 300 times before it

needs to be replaced. KoamTac recommends replacing the battery every six months as

a declining battery will cause noticeable performance degradation in KDC. Replacement

batteries can be purchased from a KoamTac distributor. Batteries should be disposed

properly according to the WEEE regulation. The steps for replacing the battery are as

follows.

1. Disassemble the KDC back cover by unscrewing the middle screw.

2. Remove old battery and replace with new battery.

3. Reassemble the back cover.
