Q: What is the best way to handle charging/discharging/storage of lithium ion batteries?

A1: How to prolong lithium-based batteries

A2: Lithium ion batteries are good for 300-500 charge/discharge cycles. A "charge/discharge" cycle generally consists of an extended charging period, and an extended discharging period. A quick charge, listening for 30 minutes, and charging again, for example, does not constitute a full "charge/discharge cycle", but could rather be considered a portion of one.

Also, many, many factors affect how much you get out of each charge, as well as how long the battery will last overall. The main factors include charging patterns, the routine amount of discharge (i.e., Do you use it until it dies? Use it for an hour or two and recharge?), temperature, storage, usage frequency, etc. Lithium ion batteries do not take kindly to frequent full or complete discharges. When possible, the optimal usage pattern - for any lithium ion battery - is a partial discharge, followed by recharging. A partial discharge can be anything less than a full discharge. However, an occasional full discharge is desirable (e.g., once every 30 charges) to calibrate the battery. Lithium ion batteries do not significantly degrade, or develop "memory", even if charged at irregular intervals; irregular charging is acceptable. An iPod can also safely be attached to external power for extended periods of time. (For extremely extended periods of time, such as months, the battery will essentially be the same as if it were in "storage"; lithium ion batteries do not store well for extended periods of time at full charge. However, there is no way around this under these circumstances.) When possible, always use the AC adapter (or vehicle adapter) for extended charging, not a FireWire cable attached to a computer.

It is generally recommended to store lithium ion batteries at about 40% charge. However, the iPod draws power even when it is off, meaning that it will soon deplete any charge that it has. If you will be storing your iPod for an extended period of time (i.e., weeks to months), it is recommended to store the unit in a cool place; charge level is unimportant, as the charge will be completely depleted after several days. The most harmful combination for storage is full charge at high temperature (i.e., in a hot car).

normaal gezien moet ge +- de eerste 5x uw batterij volledig laten afgaan. vanaf dan maakt het ni veel meer uit... (da hebbe ze mij toch al 2x in de winkel gezegd )

ze zouden gewoon eens nucleaire batterijen moeten maken ,energy forever !! :applause:
Hehe terroristen zouden dit al te graag horen

dan zouden ze een kernbom maken op batterijen



ik laad men gsm alleen maar op als men batterij bijna helemaal leeg is
ook al mag ik deze opladen wanneer hij nog maar half leeg is of niet
ik merk toch een verschil van levensduur

ik heb men gsm al een jaar en ik doe nog altijd 11 dagen met mijn batterij
vroeger had ik de gewoonte mijn gsm altijd op te laden wanneer hij nog half vol was
en dit verkort de levensduur enorm
