No they don't lithium prefers to be charged to ~40% and then kept at a pretty cold but above zero temperature.

Ni-cad are rechargeable that require full cycling. Ni-Mh are the "memoryless" Ni-cads.

This may apply to other manufacturers - HP reckons its batteries should be calibrated every 3 months. This means charging the battery to full capacity and then discharging completely by setting your laptop's power options to "always on".

Ive had my laptop for 4 and a half years now, and ive never had a problem with the battery. Its always plugged in, and the only thing that keeps breaking is the connection from the power supply on the back, ive gone through 3 now, and they arent cheap.

Irrelevant of what manufactures say, its all the same technology (even the macbooks li-poly is just an evolution) the batteries should all be looked after in the same way if you really want to be anal about it. But essentially no matter what you do they die a death however you look at it. I realise i should take care of my battery but i don't bother and tbh its doing just fine as it stands after 2 years of general abuse...

My lenovo has some battery management thing that's integrated into the power management software. Think it stops the battery charging fully all the time (sometimes stops at 97%) and will tell you to discharge the battery every now and again if it's always plugged in.

Never been an issue for me but a few of my office bound collegues have found it quite useful.
