Nickel-cadmium (NiCd) Do run the battery fully down once per month; try to use up all energy before charging. Do not leave battery in charger for more than 2 days because of memory. Avoid getting battery too hot during charge. Charge methods: Constant current, followed by trickle charge when full. Fast-charge preferred over slow charge. Slow charge = 16h Rapid charge = 3h Fast charge = 1h+ Nickel-metal-hydride (NiMH) Do run the battery fully down once every 3 months. Over-cycling is not advised. Do not leave battery in charger for more than 2 days because of memory. Avoid getting battery too hot during charge. Charge methods: Constant current, followed by trickle charge when full. Slow charge not recommended. Battery will get warm towards full charge. Rapid charge = 3h Fast charge = 1h+ Lithium-ion (Li-ion) Do charge the battery often. The battery lasts longer with partial rather than full discharges. Do not use if pack gets hot during charge. Check also charger. Charge methods: Constant voltage to 4.20V/cell (typical). No trickle-charge when full. Li-ion may remain in the charger (no memory). Battery must remain cool. No fast-charge possible. Rapid charge = 3h Lead-acid (Sealed or flooded) Do charge the battery immediately after use. Lead-acid must always be kept in a charged condition. The battery lasts longer with partial rather than full discharges. Over-cycling is not advised. Charge methods: Constant voltage to 2.40/cell (typical), followed by float held at 2.25V/cell. Battery must remain cool. Fast charge not possible; can remain on float charge. Slow charge = 14h Rapid charge = 10h More knowledge about battery and charger ...
