Charging The Ni-Mh Battery Cartridge (Using The Cu-6001); Ni-Mh Battery Cartridge Loaded In The Bht-6000 - Denso BHT-6000 User Manual

5.5 Charging the Ni-MH Battery Car-
tridge (using the CU-6001)
You may charge Ni-MH battery cartridges either loaded in the BHT-6000 or all by
themselves.
Service Life of Ni-MH Battery Cartridge:
NOTE
Ni-MH batteries used in the battery cartridge will gradually deteriorate during the
repeated cycles of charging and discharging due to its properties, even under
normal use. When the battery service period becomes shortened due to its deterio-
ration even if it has been charged for the specified hours, replace the battery
cartridge with a new one. Generally, it is necessary to replace the battery cartridge
after it has undergone approx. 200 cycles of charging and discharging operation.
Memory Effect:
If a Ni-MH battery undergoes many cycles of imperfect charging and discharging
(e.g., one-hour recharge followed by one-hour use), the service period may become
shortened before the service life is really expired, just as the battery memorizes the
use conditions. It is called "Memory Effect." The memory effect can be avoided
by discharging a Ni-MH battery fully before charging.
For the Ni-MH battery cartridge, use the CU-6001 or C-600 for fully discharging
and recharging.
