Calculating the average charging time
Depending on the type, age and remaining charge in the
batteries, the charging process can take various lengths of
time. The average charge time can be calculated using the
following formula. Take note however that the times given are
only guiding values.
Charging Time (min) =
Battery capacity (mAh) × 1.2 × 60:
Charging current of the product (mA)
Automatic charging control/ Retention charging
This product controls the charging time for Ni-MH
rechargeable batteries separately. This control is based on
the –Δ V ("Minus Delta V") calculation. In mathematics,
with Delta Δ differences are indicated. In this case, "Minus
Delta V" means a negative voltage difference. This charge
identification makes itself useful in the following effects: Should
a rechargeable battery be charged with a constant current,
its voltage rises continuously. When a rechargeable battery is
full, its voltage reaches a maximum but falls again slightly with
further current flow. This light fall in voltage is recognised by
the charging electronics and the charge process is terminated.
The product automatically switches to "Retention charging".
This means that the batteries are no longer being loaded
with constant current, instead, with short current pulses. This
counteracts the selfdischarge and the batteries are kept in a
state of full charge.
