Note:
The discharging rate of Li-Ion batteries is very low. These batteries can be stored for a
long period of time (up to 1 year) in a cool and dry place.

Pushing:
When a fully charged Ni-MH rechargeable battery is connected to the charger, it is possible to
top up the battery or "push" it by
pressing
the select button once. The Charger One tries to
charge the battery with a current of 0.9A. The display flashes: "
battery type
push...
battery
type
full"
A bulit-in delay of 30 Minutes after the end of the charging process prevents your battery from
being over-charged. During this period, pressing the button will not start the pushing function.
This feature is only available with Ni-MH rechargeable batteries.
Changing the charging parameters:
It is
not
recommended to change any of the charging parameters if the battery is new and
does not show any drop in performance.
However, old batteries that no longer give maximum capacity can be improved by changing
the charging current and/or the maximum chargeable capacity. Older batteries often have an
increased internal resistance that even increases with high charging currents. Reducing the
maximum charging current to a lower level could result in a notably higher end capacity. Due
to the unreliabilty of old batteries at charging currents below 0.8A, it is also necessary to
adjust the maximum chargeable capacity. This prevents the battery from being overcharged
by the charger which cannot recognise a weak, old battery.
Example: NiMH rechargeable battery from 1996 (3.6 Ah). Charge using NiMH program with
charging current set to 0.6A and max. chargeable capacity set to 5.0 Ah.
To calculate the max.chargeable capacity use this calculation: nominal capacity x 1.3.
All settings are stored by the Charger One when disconnected from the power supply so it is
not necessary to set the charging levels each time an old battery is charged.
Reset to factory defaults:
If you entered the programming mode by errror or wish to go back to the factory settings,
please carry out this procedure:
Unplug the Charger One from the AC/DC adaptor. Do not have the battery connected to the
Charger One! Now plug the Charger One to the AC/DC adaptor while holding down the select
button. The Charger One display will show its name and version number. Release the button.
The Charger One has now been reset to the default setting.
Ensure the displays shows "
battery type
ready for...charge". If it does not, toggle to the
correct battery mode by pressing the select button (repeatedly).
