Anybody have luck with with ebay sellers? they say new unbroken seal Lenovo OEM and have thousands of feedback...and its like $70 or so.

$70 sounds about right. The thing you have to be concerned about with an eBay battery is how long it's been sitting around, which may effect the charge capacity. I recently bought a new R400 battery. When I got it, the charge capacity was 48w, but the design capacity is 56w. I recalibrated it and it went up to 52w. I haggled with the seller and got $10 off, which made it $36 for a new six-cell battery.

how do you go about recalibrating a battery?

It's in the battery optimization software called power manager.

Amazon often has these around 80.. today its at 83, I bought one 2 weeks ago, has 2013 -04 manufacture date.. for 10 bucks more, its better deal than ebay
