As we know the battery life for the jasJar isn't exactly mind blowing...
However, i was thinking is it safe to leave the m5000, plugged to the mains? and the logic being the less you use the battery the longer the life of the battery over time?

or, is it bad to keep the device charging as this limits the life of the battery? is anyone a expert in this area? :roll: :?

Li-Ion batts are better off with frequent short charge than deep charging. It performs best if kept at 40% level. Once in a while, maybe 30 charge cycle, do a full discharge to rest the gauge and your batt should last you quite a while. By the way, all li-ion have a lifespan of 2 -3 years and the clock starts ticking as it leave the production line!

so its not a good idea to keep it on mains power, so its not using the battery?

unfortunately, universal has li-pol battery. (ok, it's not too much difference)

This site explains quite detail about batteries: http://www.batteryuniversity.com/partone.htm

Are you advocating that we should take it off the charger when it reaches 40%?

Or wait till it reaches 30%, then charge it up to 50%, and so on, so that a great deal of it's time is spent at 40% or what? I'm confused.

If storing the battery long-term it is best stored @ 40% charge, wrapped in a bag and kept in a fridge (not frozen).
To maximise battery life avoid repeated deep-discharges.
Keeping the unit on a charger when available will help to maximise the lifespan of the battery.

Yes, that is correct and it is safe.

Hi,

Perhaps a mute point but replacement batteries cost about £20 - If i got 2years out of it, i think thats good value.

Had a M2000 for almost a year never really charged unless the battery level was critical and (guessing) I think I got the same lifetime between charges as when i first had the device.

Yeah - people suddenly became very interested in LiIon battery life when the iPod replacement battery issue became an issue :wink:
