Charge your Sansa player for approximately 3 hours prior to first use. Upon first time use, it is recommended to condition the battery to maximize the useful life. The player SHOULD be fully charged and then fully discharged before recharging. Repeat this cycle for the first 3-5 times you charge the player.
This is not necessary with the new Li-Po batteries. There’s no memory or conditioning needed.
[Quote]: A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges. [End Quote]
