User manual

It is important for the circuit setup for a simple charger that the charging end volta-

ge is stabilised/limited to max. 1.9 V. If the current used for charging is lower, this

is unproblematic and charging merely takes longer. For many rechargeable battery

types, a gentler charge (at a lower current) is rather of benet and contributes to a

higher number of charging cycles. Quick-chargers charge rechargeable batteries in

the shortest time possible.

On rechargeable battery packaging and the rechargeable battery housings of the

NiZn rechargeable batteries there is the charging recommendation:

AA Mignon: 12–15 hours at 150 mA, quick-charge capable

AAA micro: 12–15 hours at 55 mA, quick-charge capable

At the pre-set charging circuit, the charging end voltage is implemented with the

orange LED. This LED shows the charging status at the same time. When the

rechargeable battery is empty, the LED will not light up. If it has a bigger charge, it

lights up brightly. The current is controlled by the resistor R1 and the red LED.
