After only 10 cycles, my ultrabay battery is down to 22.71 Wh from 29.1. I ran a search and saw may people saying that ultrabay batteries were pretty bad, but really this bad?

What are my options with this? I've only had it for a few weeks, is mine defective? Can I get a replacement?

I had one in my T43 with no problems.

They aren't bad per se, just that most tend to start declining in capacity pretty quickly simply because of how they are used.

Mine is at max capacity after 22 cycles.

Also, it's kind of weird, but my main battery's capacity seems to have increased... from 84.24Wh to 85.61 Wh. (The main battery has gone through 13 cycles.)

Call Lenovo and request a replacement. Reason: not holding a charge.

How's lenovo at rma's? Am I going to have to wait a month for the replacement like I did for the original?

I think it depends on their inventory. When you call them ask them how long. They may not ask for the old battery back but I think they will send you the replacement without getting the old bat first.
Can't hurt to ask them.

my 1st lost about 4wh of capacity after about 5 cycles, I got it replaced. My 2nd one has been fine (so far) with about 10 cycles on it

So I made a warranty claim around 5pm yesterday, and they told me that there were only 3 left so they can't guarantee it'll get to me, and if it did ship out it wouldn't get to me until tuesday. Today (Saturday), I get a knock on the door and to my surprise it's a lenovo shipment. They first classed me a new battery. So awesome!

I find whenever a battery does not seem to be preforming as it should it is worthwhile to take a look at the power saving scheme you are running.

I thought a battery that came with my factory refurbished T23 I bought about a year ago was gone already. I hardly used it on battery power. I was down to 15 minutes per charge.

I pressed F8 on startup, picked the safe mode command prompt and just walked away and let the battery run down and shut off. I then recharged it. Each time I did this, the charge took significantly longer and the T23 ran longer. By four cycles of this, I had a battery that operated my notebook for over 2 hours a charge. Oh, I also went into "Power Options" in Control Panel, to "Alarms" & changed Low Battery Alarm & Critical Battery Alarm to 3% & 2%

These li-ion cells may not have a memory chip but these li-ion power packs do generate what techs call "digital memory effect" Apparantly, you bypass this by freeing the battery from the notebook power saving utility for a few cycles or more.
