Look at the wide range of charger for example for NiMH accumulators.
Then take a look for the wide price range of those. I cannot believe
that all chargers will take care the same (good) way of your accumulators.
It is the consumer, who err. It starts with calling a accumulator a battery... ;)

It is ok, that it seems to be odd to you.
I simply dont want to waste things.

Best regards,

This is a lithium ion battery, not NiMH.  They are very different chemistries.

Other than time?

So do I  :P

Without going into technical stuff, my advice is :

1- DO Full charge when rockbox battery meter is about to reach 30~20%.
2- DON'T charge when  rockbox battery meter is over 80%.

So for instance if the meter is at 50%...
... and you will be able to full charge when ever necessary, don't charge.
... and you won't be able to recharge even when desperately wanting to listen to music while hiking or whatever, charge.

If you have several players and don't use some for a long time :
Make sure to turn them on from time to time, check the meter and full charge if needed.

That's what I do with a couple of Sansa Clip & a couple of Cowon D2.
> My D2's are 5~8 years old and battery life is still ok (meaning no idea how long they last but based on brand new 50hrs expected, that helps)
> I have the feeling the Sansas are getting a bit short but still not to a point where I have to recharge all the time

[Saint]:
While the advice given here isn't /bad/, battery chemistry and construction has been at a stage where users haven't needed to care about this for years.

Batteries degrade over time with use, it happens, its unavoidable.

But for a long time now consumers have been able to entrust the charging circuitry of <device> to look after the battery itself, and make a damn fine job of it.

Really, the only advice I would offer is "Don't leave it plugged in, charging, for weeks on end if you're not actually using it" - other than that, just do as you please. If you're near a charger, and its convenient to charge...do so.
