Automatic detection of battery charge level
Protection against overheating and overcharging
The Tensai TN-2000U charger is a universal, fast and automatic charger that is compatible with all Ni-MH battery types – D (R20), C (R14), AA, AAA, 9V block.
The blue illuminated graphic display shows the current operating mode and the battery charge level in percent.
The "Discharge" mode allows batteries to be fully discharged before charging (except 9V block batteries). This extends their lifespan and prevents the memory effect .
ΔU detection ensures that the charging process is automatically stopped as soon as the batteries are fully charged. This prevents undercharging or overcharging of the batteries.
Additional features:
- Built-in USB output (5V, 0.5A): Allows the charger to be used as a power supply for charging mobile devices such as smartphones, tablets or power banks.
- 12V DC port: Allows operation with a car adapter to power the charger via the car's cigarette lighter. Adapter not included.
