Battery Conditioning & Battery Maintenance:

• All current cellular battery chemistry will give you about 300-500 charge cycles, depending upon your treatment of the battery. Your battery will perform best if it is charged after being warmed to room temperature.
• For ALL batteries: To achieve full battery capacity, new batteries must be charged with the phone off for at least 24 hours before initial use. Note that a new battery's full performance is only achieved after 2-3 complete charge and discharge cycles.
• For NiCad (Nickel Cadmium) batteries: A slow charger works best on Nickel Cadmium batteries.
• For all other batteries (Nimh, Li-Ion, Li-Polymer): A rapid charger works best, even though it should charge for 24 hours initially.
• For vibrating batteries: Note that the battery does not vibrate when the phone is connected to or placed in any charging device.
