Hi, I have a ThinkPad T510 and recently bought a genuine Lenovo 70++ Battery. I get an average of about 3 hours out of it. Lenovo Power Manager says it's in good condition with a Full Charge Capacity of 93.52 Wh. The battery was manufactured in July of this year (2016).
I also have a stockpile of new genuine Lenovo 25+ Batteries at my work. They were manufactured in 2015 and can only last about an 1.5 hours. Is this normal? I don' t do gaming on my laptop and don't use it very heavily (I don't have multiple browser tabs open while running tons of other stuff at the same time). I've heard people getting 8 hours out of these batteries! Meanwhile, I carry around 5 genuine Lenovo batteries in my laptop bag so I don't run out at the end of the day! Any suggestions? My arms are getting tired!
