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 (see Section 2.9). 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.
Battery refresh function
If the capacity of a NiCd or NiMH battery drops noticeably, the battery can be refreshed using two to three full charge and discharge cycles.
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. For this reason, the entire battery pack is always replaced in Leica Geosystems service centres. The Li-Ion and camcorder type batteries are in sealed housings and the cells cannot be replaced.
