This has been working fine on my laptop and I have been using it for about couple of months by now. the full charge holds about 3 hours pretty well.
F.S
I had to put the old battery back into my laptop to get it to turn on.

purchased this to replace the aging battery on my SL410. Works exactly as my original battery did when it was new. Lets see how long it holds up!

Battery for the SL510 Lenovo was dead and time for a new one. Choose Anker based on reviews and stayed away from the mixed reviews of the cheapest ones and stayed away from the OEM overpriced ones. Glad I did. Quality... 1.5 year warranty and Customer Care that is interested in your satisfaction. Please do follow instructions of initial break in tips for longest life and longevity and you will be happy.

Updated review: Ordered battery for Lenevo SL410 laptop as my original battery could not hold charge anymore after 4 glorious years of performance. I shopped around and found Anker to be a respectable name among non-OEM suppliers. Battery arrived promptly with immaculate packaging. Snapped right in place snugly. Was impressed with 2-4 hours life (variable based on settings and usage) of the replacement although I don't understand why the battery would not charge to 100%. The maximum it would charge to was 99%, which was strange but okay by me. However, the battery died on the 30th day or ordering as it could not hold a charge any more. So I contacted Anker who promptly sent me a replacement battery, which works fine (99% max charge issue with the new one as well). However, I would like to rate Anker's service as 5-star becuase of multiple follow-up emails by them to make sure I was satisfied with the replacement.

Well I don't write much review comments, because I am little lazy :). But I liked this product so much that I thought I should write review. I purchased this battery for my Thinkpad Edge 520. I was little worried but this battery worked like a charm. More than 3 hours of battery backup till now. I bought it just 3-4 days back so will update after an month also. Let's see how it works after one month. Till now I am very happy with this product.

7/8/14 - Disappointed thus far in this battery - have had great luck in the past with Anker products, but this one, not so much. In fact, it doesn't last any longer than the Lenovo battery it replaced. It starts off great, but drops off fast. I powered it up today and for the first few minutes, it said over 3 hours left. An hour later, and I have 35 minutes left. And it's just been sitting here idle.

UPDATE 7/18/14 - As expected, Anker took care of this immediately and sent me a replacement. I am happy to say that so far, I've gotten 3 hours per charge, which is good considering how much the laptop was used. Back up to a 5-star review - thanks Anker!

Bought two for use on a cross country flight. Needed only one each way. In other words, it worked like the genuine, original battery.

I have had a Lenovo Thinkpad since I started college five years ago. Our school has a laptop program which you get to exchange for a new one every two years. I had chosen to keep mine because it was no longer under contract and it was mine. I needed a new battery, even though my computer wasn't even a complete three years old yet, the battery was shot. I couldn't afford a new battery from Lenovo for $170.00. And now I say why spend that much when you can get this battery which has a better life than mine ever did. It holds more of a charge and is reliable. I SERIOUSLY RECOMMEND this product to any Lenovo owners!
