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 batteries can be stored for an unlimited period in any state of charge. 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.

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. 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.
