I had been told a long time ago by an engineer, that it was probably best to go through longer charge cycles with Li-ions. It seems that advice was not really correct, according to Wikipedia, and the Battery University.

Apparently Li-ions should be charged more frequently, although I am certain I have heard reports of people suffering ‘memory’ style patterns in some Li-ion batteries when charging really frequently. Maybe this is just the low number of charge cycles these batteries can actually cope with. I should think charging at around the 10% mark is actually the way to go, but not to drain them too low, as apparently this is bad for them too.

Li-ion lifetimes can be extended by cooling the batteries too!

I remember the advice I got regarding AA batteries when I was using a Psion 5, in those days, gently crushing the battery and / or leaving it on a radiator for a few minutes would generally give you enough lifetime to make a short trip home etc.

Battery specs are a pain still, but hopefully it won’t be too long before that changes.
