La Crosse Technology BC-9009U Charge Mode, Charging Time with various charging current

CHARGE MODE

Charging at 200 mA is the default-operating mode of the charging unit.

When only one or two rechargeable batteries are charged, provided that only compartment 1 and compartment 4 are used, a charging current up to 1500 or 1800 mA may be set by the pressing the CURRENT key.

On the other hand, when charging three or four rechargeable batteries at the same time, user may select a charging current of 200, 500, 700 or 1000 mA.

Note:

User shall always observe the recommended maximum charging current of the rechargeable batteries. In general, 200 mA is a recommended charging current if rapid charging is not necessary. It is definitely safe and optimum to the rechargeable batteries.

It may be necessary to charge and discharge the new rechargeable batteries several times in the beginning before the optimum capacity of the rechargeable batteries can be obtained. It is recommended to use the "Refresh" mode for new rechargeable batteries in order to achieve the optimum battery capacity.

When the transformer has been plugged into the power source, the version number of the charger (for example “33” ) will be displayed first. Then all the segments will light up momentarily and the “null” sign will be shown before batteries are placed. If damaged batteries are placed into the charging unit, the charger will also show “null” on LCD.

“null” displayed - No battery or damaged battery is placed to the charging unit
