Specially designed for the special requirements of a DECT telephone. The batteries have a very low self-discharge, which is the ideal condition for operation in a cordless phone. Due to the best cycle stability, the NiMH cells can be recharged up to 1000 times. They can be charged with a high charging current, which allows very short charging times. The batteries can be used at temperatures from -20 to +50°C. NiMH rechargeable batteries can basically be used wherever disposable batteries are used. You can save money and protect the environment. The self-discharge is 10 times lower than with normal NiMH batteries. After one year, about 80% of the initial capacity is still available. This was made possible by a special separator that drastically reduces the unwanted internal current flow. Since the batteries are delivered pre-charged, they can be used directly.
