OPERATION
You can insert any number of rechargeable batteries into AA/AAA charging trays up to a maximum of four;
in this process, you can also mix and charge AA and AAA rechargeable batteries (Fig. B Insert the side with
the positive terminal into the charging bay first to place AAA rechargeable batteries in the corresponding
charging tray. When inserting rechargeable 9V block batteries into the corresponding charging tray, make
sure that the rechargeable batteries are inserted with the positive terminals pointing towards the outside
(Fig. C). Always note the illustrations and marks in the charging bays of the charging trays and do not stack
rechargeable AAA and AA batteries.

If the status LED for one or more rechargeable batteries shows that the
charging process has been completed, you can just remove the charging tray from the corresponding
slot to remove fully charged rechargeable batteries. You need not switch off the charger for this purpose.
After having reinserted the charging tray into the slot, the charging process of the rechargeable batteries
remaining in the charging bay continues. Once the charging end voltage of rechargeable batteries has
been reached (corresponding status LED lights up green), the quick-charging process is interrupted (over-
load protection) and the rechargeable batteries' charging status is maintained at this level until the battery
is removed.
Deep discharge: If a rechargeable battery has been deep discharged, it may be possible that the
charging electronics identify it as faulty and the corresponding status LED flashes red. Leave the recharge-
able battery in the charger for approximately 15 minutes, then remove the corresponding charging tray
from the charger to interrupt the charging contacts and reinsert the charging tray into the charger. If the
corresponding status LED then continues to flash red, the inserted rechargeable battery is damaged. Cor-
rectly dispose of the rechargeable battery at an official collection point.
If fully charged rechargeable batteries are reinserted and charged, the charging electronics identify them
as fully charged after a few minutes and the charger maintains the charging levels.
You can charge up to sixteen rechargeable AA or AAA batteries and up to eight rechargeable 9V block
batteries simultaneously in the Palmer BC400 charger. You can also mix charging trays for rechargeable
AA/AAA batteries and charging trays for rechargeable 9V block batteries in the charger.
