The batteries are particularly suitable for devices with consistently low energy consumption due to their very low self-discharge rate. They are ideal for children's toys, remote controls, alarm clocks, watches, and flashlights. With optimal cycle stability, the NiMH cells can be recharged up to 1000 times. A high charging current allows for a very short charging time. The batteries can also be used at temperatures ranging from -20 to +50 °C. Since NiMH batteries can be used wherever single-use batteries are employed, they not only benefit the environment but also save money. The self-discharge rate is ten times lower than that of regular NiMH batteries. After one year, about 80% of the initial capacity remains available. This has been made possible by a special separator that drastically reduces unwanted internal current flow. The batteries are delivered pre-charged and are therefore ready for immediate use.
