Refresh your batteries!
With the two different modes, the LCD Smart Charger+ is not only able to recharge but also to refresh NiMH batteries whose capacity has declined over the period of use.


Charging time
1,5h Charging time
Individual charging channels
Enables you to charge different numbers and combinations of cells
Minus Delta V method
Method which takes advantage of the fact that the cell voltage reduces slightly in a rechargeable battery (- Delta V), as soon as the cell is completely charged
Temperature control
The temperature of the rechargeable battery is measured whilst it is charging. If this rises above a defined maximum temperature level the charger switches itself off
Trickle Charge
Prevents the natural self-discharging process of rechargeable cells
Short Circuit Protection
Defective and short circuited cells will not be charged and will not harm the charger
Bad cell & alkaline detection
Contains criteria for switching off to prevent charging of primary cells, defect cells or cells with reverse polarity
Ready To Use
For immediate usage straight from the pack.
3 years guarantee
Global Voltage
Global voltage for worldwide use
Timer cut-off
A timer switches off after a specified time irrespective of charging status
