Don't want to start a war, but lithium batteries can really be charged up any time you want. They should really last years (some manufacturers claim 20, but that is probably overstated). The battery should last longer then the phone. Nickle metal take about 500-700 before they are toast, and will hold less and less charge cause the cells die. NIMH don't have memory. I have a 3 year old lithium for a t28w that still works perfect, and I have pure abused it in terms of charging. If was a nimh, would have been dead in 6 months.
Never leave a battery on a charger for more then 24 hours, you are over heating it. If the batt is getting real warm, try a different outlet, or remove from outlet after a couple hrs. With a SE batt, their experienced techs will tell you to always charge for at least 1 1/2 hours for a full charge, no matter how much is left.
Also, take the battery off the phone periodically. If you have ever bought regular rechargeable batteries, you will see that the instructions say to take the batts off the charger as soon as charged. Basically, the phone is part of the charging unit, even if not plugged into the wall charger. Leaving on the phone can cause freezes. What follows next comes from an SE phone designer at their US plant in north carolina. She said that because the batts tend to stay on the "charging unit (the phone)" all the time, the batts can get locked in a loop, causing phones to respond strangley, things like freezes or no LCD, so taking the batt off usually fixes this. She also said the explanation may be BS, but it works. I have seen alot of t68m's that the 0 button freezes, nokia 3395's where there is no LCD, but you knwo the phone is on, etc., and taking the batt off almost always fixes the probs.

You're right there. Most of that stuff about recharging applies to NiMH and is obsolete; Lithium-ion is not harmed by this.
However, there are problems with Li-Ion. These occurs when batteries are stored for a long time while still having some charge in them. Apparently, it creates a film of some sort of resistive material on the cells; making the battery effectivly useless for phones. This is what happened to my t28 after not using for one month - completely dead. It is also happening to my laptop. I read there are ways to fix batteries; and even to "rejuvenate" old li-ion batteries to there original capacity by putting resistors over them.
