Thinkpads Forum

Just got a brand new 9 cell T4x battery for the girlfriends T41 (thanks Brad).
This battery was never used befor so the first use date is today.
I have read and see many diffrent ways to get the most out of a new battery.
Some say you should charge it fully to 100% then drane it down to 0% and do this cycle about 5 full times.
Others say just plug the battery in and use it like any other battery.

Whats the best way on thinkpads to start off a brand new 9 cell battery??

Have your computer off (not standby nor hibernation) and charge it overnight.

Agree to the above. Charge it then use normally. Nothing esle you need to do.

Thanks for the info....
I left it charging over night.(thinkpad off). It's at 100% now.
The battery gauge says with full brightness,wi-fi on,and running Vista set to high performance , i'll get about 4 1/2 hr's from this new 9 cell.
With the LCD turned down and Vista set to power saver , it shows i'll get almost 7hr's!!.

Yah, I always get those inflated(?) 7hr readings with things set on low. Always wondered how that was calculated! In any case, my 9-cells always seem to run a long, long time after a full charge so I never paid attention if it actually ran for 7 hrs. Have fun!
