1605.5 Charging the Rechargeable BatteryCartridge (using the CU-8001/8021/8011)You may charge Ni-MH battery cartridges either loaded in the BHT or all by themselves. When chargingthem all by themselves, be sure to follow the instructions given in Section 5.5.2.Service Life of Ni-MH Battery Cartridge:Ni-MH batteries used in the battery cartridge will gradually deteriorate during the repeated cycles ofcharging and discharging due to its properties, even under normal use. When the battery's operatingtime becomes extremely short even if it has been charged for the specified hours, replace the batterycartridge with a new one. Generally, it is necessary to replace the battery cartridge after it hasundergone approx. 200 cycles of charging and discharging operation.Memory Accumulation:If a Ni-MH battery undergoes many cycles of imperfect charging and discharging (e.g., one-hourrecharge followed by one-hour use), the operating time may become short before the service life isreally expired, just as the battery memorizes the use conditions. It is called "Memory Accumulation."The memory accumulation can be avoided by discharging a Ni-MH battery fully before charging(called "refresh"). For refreshing the battery cartridge, use the CU-8001/8021/8011 or C-600.If left unused for a long time, the battery cartridge may have been inactive. Charge and discharge sucha battery cartridge several times before use.5.5.1 Rechargeable Battery Cartridge Loaded in the BHT(1) Turn the CU-8001/8021/8011 on.
