Defective batteries

Even in the case of correct handling, it may occur that a statistically small number of batteries fail prematurely. A possibly defective cell must never be replaced in a battery pack. The cells in a battery pack are all from the same manufacturing batch and thus have the same manufacturing tolerances. If new and old cells are mixed, the weaker (old) cells in the battery pack are more heavily loaded and further failures inevitable. The Li-Ion and camcorder type batteries are in sealed housings and the cells cannot be replaced

Battery Life

The life of batteries is primarily defined by the following factors: • Electrical loading • Charging method • Temperatures on charging, discharging and storage • Quality of the cells Losses in capacity caused by incorrect charging. Reduction in battery capacity is normally due to age. However it can also be the result of storage at excessively low or high temperatures.

Memory effect

The «Memory Effect» occurs if the same charging and discharging (partial discharge) conditions are continuously applied to a battery. The battery then no longer provides the full capacity. The operating time per battery charge reduces. If the capacity of the battery drops noticeably, it is recommended to subject the battery to the refresh function 2 to 3 times. The memory effect occurs particularly with NiCd batteries. With NiMH batteries the memory effect is not so pronounced. Li-Ion batteries are not influenced by the memory effect.
