Specifically designed for the unique requirements of a DECT phone. The batteries have a very low self-discharge rate, making them ideal for use in cordless phones. With excellent cycle stability, the NiMH cells can be recharged up to 1000 times. They can be charged with a high current, allowing for very short charging times. The batteries can be used at temperatures ranging from -20 to +50 °C.

NiMH batteries can generally be used wherever disposable batteries are used. The self-discharge rate is ten times lower than that of standard NiMH batteries. After one year, about 80% of the initial capacity remains available. This is made possible by a special separator that drastically reduces unwanted internal current flow. Since the batteries are delivered pre-charged, they can be used immediately.
