You can charge anytime, in fact Li-Ion batteries like in the N900 prefer not being drained too much or being charged too hard. If you can keep them between 20 and 90% you'll probably get the best life out of them.

I think with this type of battery the recommended way is many short charging cycles rather than use it until it's dead, charge it until it is full. In other words, put it on charger whenever possible...

It's just general lithium-ion battery advice. Also, slower, low-power charges are better. So the AC wall charger which puts out 1200mA an charged the N900 really fast is actually worse for its battery long-term than the day-long USB 500mA recharges. Go figure

Cause after 2 hours it's at 97%... till I wake up.
Maybe this is the reason it never gets to 100%??

Maybe do
hal-device bme | grep battery
in x-term and look at
battery.reporting.current (current state)
battery.reporting.last_full (last time charged)
battery.reporting.design (what it should be OOTB)
?
These are mAh. If this is somewhere near (last_full / design) * 100 = 97% this is explaining what it shows.
Mine is at 14% charged with current / design = 187/1250 = 0,149 = 14%
and has a ratio of 1044 / 1250 = 83,52%. I will do a complete recharge and report the results afterwards.

More info: http://wiki.maemo.org/Batteries
I dont tend to charge mine until its low (just entered red) as there are a limited number of charge cycles (several hundred) but not entirely sure what defines a charge cycle as you can topup charge without that counting.

When the operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.

That's the reason they released the new update. Nokia wants to sell more batteries
Oh and good discussion about battery percentage linked from bottom of battery wiki: https://bugs.maemo.org/show_bug.cgi?id=7636
