@mke73 and you other battery experts. What are your recommendations for charging/discharging the Archos battery to ensure a long (and safe) life! Thanks
Avoid deep discharges if you can; avoid temperature extremes; if you use a different charger, try to find one with the same specs or, if that's not possible, always go for lower amps (the 101 has a 2 amp charger).
Charge the battery often, ideally whenever you see the opportunity. Not topping off won't harm it, but charging fully is always better. Don't leave the 101 on the charger for days on end (it's not harmful for the battery per se, but it will raise the temperature unnecessarily). The same goes for the habit of using the device on mains for long periods: Don't. It heats up the device and can shorten battery lifetime dramatically.
Basically there are two rules of thumb:
1. Keep the battery nice and cool , but not cold, and
2. keep the battery busy. It actually likes to work.
Do those things and, depending on intensity of use, the battery should be good for two to five years.
One rather important tip: Don't buy spare batteries if you don't need them right away. LiIon and LiPol batteries deteriorate, whether you use them or not, so buying that cheap spare for use in two years will turn out to be money wasted. There are ways to store them, but they're complicated, require monitoring and are never100% effective.
This is also why, when you do buy a spare, you should always inquire about the fabrication date. Not only does it make you look knowledgeable but, if the salesdroid goes "Duh?", you have your cue to walk away.
