5.3 Li-Ion batteries 5.3.1 Li-Ion Battery Maintenance The IQ Force is equipped with a rechargeable Li-Ion (Lithium-Ion) battery. Rechargeable batteries gradually lose their charge when not being used and may suffer irreversible damage if the battery reaches and remains in a state of complete discharge. Honeywell Analytics recommends fully charging the IQ Force Li-Ion battery at two-month intervals during storage to prevent damage to the battery. It will take a maximum of eight hours to fully charge the Li-Ion battery. The IQ Force may also be stored for long periods of time on a powered IQ Force charger with no ill effects. Storage of Li-Ion batteries at temperatures above CF may damage the internal components of the battery and lead to reduced battery capacity and voltage.
