Cell Type

Most survey batteires currently use nickel-cadmium (NiCd), nickel-metal hydride (NiMH) and Lithium Ion (Li-Ion) cells. The cell type is marked on the battery.

NiCd

NiMH cells have a higher internal resistance than NiCd cells and are therefore not suitable for such high charging and discharging currents, or low temperatures as NiCd cells. The voltage of the battery collapses rapidly at negative temperatures and high current loading. This can result in the activation of the deep discharge protection fitted in all Leica Geosystems batteries. This means that the full capacity of the NiMH batteries cannot be drawn at low temperatures. Leica Geosystems only uses NiMH cells that provide problem-free operation when supplying the current drawn by all Leica equipment, even at –20 °C (–4 °F).

NiMH

NiMH cells have a higher internal resistance than NiCd cells and are therefore not suitable for such high charging and discharging currents, or low temperatures as NiCd cells. The voltage of the battery collapses rapidly at negative temperatures and high current loading. This can result in the activation of the deep discharge protection fitted in all Leica Geosystems batteries. This means that the full capacity of the NiMH batteries cannot be drawn at low temperatures. Leosurvey only uses NiMH cells that provide problem-free operation when supplying the current drawn by all Leica equipment, even at –20 °C (–4 °F)

Li-lon

Li-Ion cells have a high energy density. This minimises battery size and weight. It is a low maintenance battery; there is no memory effect and no scheduled cycling is required to prolong the battery’s life. In addition, the self-discharge is less than half that compared to NiCd. The batteries have a lifetime of about 3 years from manufacture. This is caused by internal oxidation which is hastened at high temperatures. The Li-Ion batteries supplied by Leosurvey have a protection circuit to maintain safe operation, limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge. In addition, the cell temperature is monitored to prevent temperature extremes.
