I've got an Asus Eee 1005PE "netbook" laptop with a 6-cell battery. The usage pattern has always been to let it drain down to 10-40% capacity and then let it recharge during the night. I realize that 2½ years is a respectable age for a laptop, and no less for the battery. Soluto is reporting that the battery is 46% worn.
What can I do to refresh this battery? (Besides replacing it, obviously.)
