The gentle charging with low current guarantees a long life of the eneloop batteries. Two LEDs let you know the charging status of batteries. Space-saving design as plug-in charger.Eneloop batteries have a low self-discharge and are supplied pre-charged. Not only are they ready to go immediately after purchase, they also keep their cargo for a long period of time. This means that 85% of the capacity is still available after one year of storage. So your device is always ready for use and guarantees that the required energy is always available when it is needed. One of the most important requirements of a battery is its service life, i.e. the number of charge/discharge cycles that a battery can withstand without losing power. Clearly the biggest advantage of the eneloop is that it can be recharged up to 2100 times and then recycled. In the long run, this is not only cheaper, but also environmentally friendly.This text is machine translated.
