1A bit short of expectations
By dirocco
I was pleased with delivery and that this was an OEM part. However, the internal mfg. date detected was 2006, and first used date 2007, with a sticker on the outside of the battery with a written date of 12/11. So, after a number of Lenovo battery utility deep-cycle charges, the best I can get is 89% of rated capacity. So, does that meet expectations?? Not from prior experiences with other LiIon battery vendors, where I am advised 3 to 4 years on the shelf is about it.The product page did not mention anything about it being new, but actually old.I am waiting to hear from Amazon and this vendor, because this is a bit contrary to the vendor's general ratings. I will update upon a response.Update: Amazon processed a return and credit, and I bought the same product from a national vendor via Amazon. I am pleased the product I received this time actually had a very recent internal manufacturing date, and exceeds ratings. So buyers beware with batteries suggesting they are new; ask beforehand if they may have been on the shelf for 5 years!!!

5Great Replacement Battery
By Amazon Shopper
I needed to replace the original 6 cell battery that came with my Lenovo T60, as it had gotten to the point where I only had enough power for about one hour of laptop use. I replaced it with this 9 cell battery and increased the amount of time I can stay unplugged to about four hours. This is the actual Lenovo model and so it fits perfectly into the T60 and stays put. This is important because I read where this was not the case for some cheaper, non-Lenovo batteries that were supposedly meant to work with the T60 but didn't truly fit very well. This battery cost more than these cheaper brands but it fits perfectly. It also costs about 40% less on Amazon than buying it directly from Lenovo. An excellent replacement battery.

5Real Deal
By VwOfSoCal
A real Lenovo battery at 2/3rds of what Lenovo charges. Fits my T61 as expected, works well, and none of the annoying "not a real lenovo battery" warnings the clones cause.
