Charging Termination - Husky MP2500 Manual

11.5.4 Charging termination

For a fully discharged battery, the MP2500 requires up to 8.5 hours to
charge a NiCd battery and 12 hours to charge a NiMH battery, After
charging for 8.5 hours (NiCd) or 12 hours (NiMH), the message Charging
Complete will be displayed. After a further period of 1.5 to 2 hours the
charging current will automatically reduce to a small maintenance charge
(NiCd battery) or zero charge current (NiMH battery). This mechanism
means that you can safely leave the unit to charge unattended. Charging is
also automatically disabled if the ambient temperature rises above 40°C
(104°F) or falls below 0°C (32°F) (nominal).
