The important bits to notice are Charge Information: Charge remaining (mAh): 6558 Fully charged: Yes Charging: No Full charge capacity (mAh): 6558 Health Information: Cycle count: 26 Condition: Normal What you care about are "Full charge capacity" and "Cycle count". You want to the former to be as large as possible and the latter, cycle count, as low as possible. LiIon batteries from 3 years ago are probably only good for 300 cycles. Newer technology I have read is good for about 1000 cycles. What Bob said about discharging it completely is worth trying.
