T61p (Model 8891, 14") -- Battery replacement recommendation

2010-06-08, 1:18 AM
I've never gotten more than 2.75 hours out of OEM Lenovo batteries. Now need to get a 3rd. I'd rather get two batteries that can do 2 hours, than a Lenovo-branded that eeks out 2.75. I currently have a 42T4623 battery. Would this one do? http://www.amazon.com/dp/B001SH2AAC Thanks.

for a T61p 2.5 hours is the most i can get of the 6 cells. 

 

instead of buying compatible battery, why not head to outlet.lenovo.com and buy the scratch/dent stock for price that is similar to these compatible batteries.

Thanks, but there weren't any 4800mAh batteries there, or for that matter any for the T60-series at all.  What are your thoughts for the battery suggested in the link?

For 30 dollars it is not bad.

Wanted to report the specs that follow from Lenovo's Power Manager v3.11a. This is immediately after the first install of the battery purchased June 26, 2010 from eznsmart: Remaining percentage: 100% Remaining capacity: 69.73 Wh Full charge capacity: 69.73 Wh Voltage: 12.42V Cycle count: 2 Manufacturer name: BATZ Manufacture date: 2010-04-23 First used date: 2010-04 Serial number: 19428 Bar-Code number: 1ZD4H7A84ET FRU part number: COMPATIBLE Design capacity: 73.26 Wh Design voltage: 11.10V Also important to note, is that the battery does not slide in easily. It exerts a bit of force on one of the guide posts, that I hope does not lead to its breakage over time. The Lenovo Power Manager does not register it as a genuine Lenovo battery.
