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. Alternatively, the batteries can be charged and then placed in the related survey equipment during normal use and discharged 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 depends on the battery capacity and temperature.

Charging temperature

The charging temperature (ambient temperature) has a significant impact on the life of the batteries. Charging at high temperature can cause loss of capacity. These losses in capacity are irreversible. Even with several charging and discharging cycles, the original capacity can no longer be obtained. For optimal charging, we recommend that the batteries be charged at ambient temperatures as low as possible (+10 °C to +20 °C / +50 °F to +68 °F). The permitted temperature range in which charging can still be performed is between 0 °C and +35 °C (+32 °F and +95 °F).
