Hey All,

I'm thinking about getting a 6cell batter for trips from West coast to east coast. On Lenovo's web site they have this info:

4.8-5.5(Integ.)/3.4-3.7(Disc.) hour(1) average battery life

What's the difference between Integ and Disc?

Anyone on a T61 actually get 4.8 hours on a 6cell? I've got an ultra bay battery as well so that should last me the whole plane flight.

Also did they discontinue the 9cell recently? I thought I was looking at it a week ago ...

MS

Those stand for Integrated graphics and Discrete graphics.

Ahh, so if I have the NVIDIA Quadro NVS 140M do I have the disc or integrated?

TIA

Discrete.

Integrated would be the Intel 3100.

4.8 hrs on a 6? lol.. I'd pay to get 3!

Lol.. I get about 4 hrs with my integrated T60 with a 6 cell doing light duty of work.

i was hoping to get 5hrs+ with a 6-7cell and Ultrabay 3 Cell on a T61 14.1 WS Integrated GPU. (normal usage browsing the web of-course)

Anyone thinks i'm on drugs? LOL On my T60 i get about 3hrs 54mins doing just browsing and chatting using the 0/7 brigthness. So i was figuring the extra cells plus better power management should give me the extra 90mins of usage

SHoTTa35 : I think you should be ok for 5 hrs with 6/7 cell + ultrabay 3cell. When using my T60 with integrated graphics with 6cell + 3 cell ultrabay I get 5.5 hrs easily. Problem is, my ultrabay 3 cell suddenly dropped 50% of life at around 35 cycles.

@msteudel:

East to west coast in Kenya? I thought they didn't have any west coast there

It's just that you state in your profile that you are from Kenya and you did not specify what country that east <> west flights would be in.

6 cell accu + Ultrabay accu sounds quite a lot, but isn't.

Design capacity of the 6 cell is 56.16 Whr, that from the UltraBay accu is 29.16Whr

After 44 cycles on the Ultrabay (Sanyo Li-Polymer) accu here it's down to 16.20 Whr on a full charge and the main 6 cell battery (Sony Li-ion) is down to 43.57 Whr after 90 cycles. Together that's 59.77 Whr, not even 4 Whr above a new 6 cell accu

Together with the stupid half-working docking software (why the hell get the screen resolutions all mixed up, see my topic for that) I call it the most stupid things of the T61 14" wide. There was no 9 cell battery for a long time. Now there is one and it's too big and too ugly. The UltraBay accu is of inferior quality while still costing just as much as Dell's D-Bay accu (what is 48 Whr, more then 50% more then Lenovo's UltraBay accu). Offcourse, Dell's D-Bay is fatter then the T61's Ultrabay, but that's better for protection for the UltraBay devices. On their DVD drives Lenovo states: "Always keep in protective case" So why the *** don't they supply such a case

Dell's Latitude D630 has a non-sticking out 6 cell battery and a frontside protuding 9 cell battery. At least they offer a 9 cell battery that doesn't look as ugly as Lenovo's. And it sticks in the middle, not off-centre (who cares?). Offcourse Lenovo back-side protuding battery is better since you can keep it as a heft when walking. You can keep the laptop on your left arm and hold the battery with your left hand. And typing with your right hand. It works quite good.

Let's count:
Lenovo's 7 cell battery: 63 Whr + 29 Whr Ultrabay battery = 92 Whr

Dell's 9 cell battery: 85 Whr + 48 Whr D-Bay battery = 133 Whr

That's why I hate Dell for not having an Expresscardslot in their D630 and why I hate Lenovo for not spying enough on their neighbours.

Just fyi: I have a T61 14" Wide with a 6 cell battery and an Ultrabay battery and have read about a lot about both laptops and made my decision in favor of the T61, but when I need long mobile runtimes I sometimes regret that decision.
