GP U421 + 4x AA ReCyko Pro

The GP U421 charger is equipped with fully automated electronics. It controls the charging process on its own. After the charging has finished, it initially goes into the minimal current charging phase completely terminating charging after a while.

The stunning charger speed is associated with intelligent diagnostics and charge management. This ensures the fastest and the most gentle battery charge.

The charger can recognize an inserted non-rechargeable or damaged battery, or a fully charged battery. There is no overcharging of batteries and the charging process itself is as cost-effective as possible.

The USB interface of the charger allows it to be used almost anywhere. The GP U421 battery charger can be charged from the electric grid, lighter socket in your car, a USB connector of your laptop or power bank or on the train or on board a plane when travelling.

These NiMH GP batteries have suppressed self-discharging and are pre-charged in the production plant. Hence they can be used right away after unpacking or after a long time of storing.

With a minimal self-discharge effect called LSD (LowSelfDischarge), the batteries retain up to 70% capacity after having been stored at room temperature for a year. Recharge the battery to gain its full capacity again

Each rechargeable battery has a limited number of charge cycles. When this number of cycles is reached, the battery capacity, or the battery's ability to conserve as much energy as possible, drops significantly.

Using rechargeable batteries with proper handling can save you considerable financial costs. When you buy this battery, you will save up to € 500 when compared to non-rechargeable batteries with a similar battery life.
