T500 users, what's your battery life?

[nowai]

Here's my specs:

T500 2.4ghz w/ 4gb ram, purchased october 09

Battery: 9-cell

Graphics: "energy saving" mode

Life:  only  2.5 hours battery life, three if I'm lucky.

Usage: just have about 10 tabs open on chrome, no flash or anything

What are you guys getting? Other reviews claimed people getting about six hours. I did the battery gauge reset earlier today, it calculated a max of a little less than three hours as well.

My friend's t400 2.2ghz (with 9-cell) seemed to last for six hours easily, possibly more than that.

also, is there any way one could possibly use the 27++ battery slice on a t500 or t400?

I ended up stumbling upon this thread ( http://forums.lenovo.com/t5/Windows-7-Discussion/Battery-Life-Decrease-In-Windows-7/td-p/168772/page... )and have the same symptoms of the fan constantly running among other things.

I'm updating power manager to see if it'll fix things, otherwise I'm getting tempted to cave and buy something else.

what is the battery condition like?

i.e. brand of cell make, full charge Wh, design charge Wh, no. of cycles. You can access these information through Thinkvantage Power Manager under battery information.

Also, what GPU are you using? ATI or Intel?

[nowai]

Cell make: Sanyo, manufactured 2009-09-28, first used 2009-10

Full Charge Capacity: 75.89

Design Capacity: 84.24 WH

Cycle Count: 188

FRU part number: 42T4619

Laptop Model: 2082-Z2U

I've only been using graphics in the intel mode.

If the battery has a 1 year warranty, should I try to get it warrantied ASAP then?

there is nothing wrong with your battery from the value that you have given.

also, are you sure the model number is what you wrote? can't find your machine model.

I too confirm 5 hours for the T500 with 9cell, maybe more. Since you are at 188 cycles I recommend reading about Lion batteries ( and rechargeable in general) - it is very important how you have been using your battery - and only you know that - and compare it with recommended usage.

[nowai]

ugh, I meant 2082-8ZU

I did't realize (and am somewhat surprised) that the battery's already gone through 188 cycles. I did just upgrade everything and put my settings into "power optimized mode" now, I'll see if it helps.

Does anyone know if the 27++ battery slice will work on the t500, or is it only for the t510/t410 ? 

[lead_org Microsoft MVP Contributor]

that is only for T410 and T510.

@nowai, try reset the battery through Thinkvantage Power Manager and see what happens.
