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 chargingReduction in battery capacity is normally due to age. However it can also be the result of storage at excessively low or high temperatures.

Storage

Leosurvey batteries can be stored at –40 °C to +55 °C (–40 °F to +131 °F). Do not store batteries inside the surveying instrument. After storage, charge the battery fully before use. NiCd NiCd batteries can be stored for an unlimited period in any state of charge. NiMH NiMH batteries must always be stored fully charged and recharged after 180 days at the latest. High temperatures and high atmospheric humidity accelerate self-discharging. We recommend storage in the range from 0 °C to +20 °C (+32 °F to +68 °F) in a dry environment. If NiMH batteries are stored in the discharged state for an extended period irreversible damage can be caused. Li-Ion Li-Ion batteries start to deteriorate from manufacture. To reduce the aging effect, store the battery in a cool place at 10%–50% state-of-charge. Li-Ion batteries do not require regular charging while in storage.
