Inter-Tel 8664 User Manual page 28

You can charge the endpoint's battery pack using a desktop charger (Models 8664 and
8665), a dual charger (Models 8664, 8665, and 8668) or a quad charger (Models 8665
and 8668). The chargers require approximately one and one half to two hours to
charge the battery pack completely.
NOTE:
Take care not to short the battery contacts on the battery pack with metal
objects such as coins, keys or paper clips. Shorting the contacts can cause permanent
damage.
NOTE:
Battery packs are not interchangeable. The Model 8665 uses the distinctive
square model BPX100 battery pack. The battery packs for the Model 8664 and 8668
endpoints are the same rounded shape but different colors. The Model 8664 BPE100
battery pack is black, the Model 8668 BPN100 battery pack is steel blue.
Only use Inter-Tel battery packs with Inter-Tel endpoints.
Do not dip the battery pack in water or throw into fire.
Do not throw away the battery pack with your domestic waste. Take used battery
packs to an appropriate collection point for recycling or send them back to your supplier
or servicing agent.
