Li-lon Cells

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.

Charging the batteries

New and stored batteries

New NiCd and NiMH batteries reach their maximum capacity only after a few charging and discharging cycles. The batteries should be fully discharged and charged three to five times. NiMH batteries that have been stored and not used for an extended period (more than a month) should be refreshed simularly. For Li-Ion batteries, a single discharging and charging cycle is sufficient. The easiest way to perform this cycling is by using the GKL221 Charging Station which has a discharge function. Al[1]ternatively, the batteries can be charged and then placed in the related survey equipment during normal use and dischar[1]ged until the equipment switches off.

Batteries in regular use

After use the battery can be placed in the charger until fully charged (the green light flashes). The charging time de[1]pends on the battery capacity and temperature.
