I didn't notice this at first when I received the battery but here is what happened. I got the battery attached to my computer, then drained the battery. Charged it to full, drain completely then charged it full again. I do this drain and charge to extend the life of the laptop batteries. The problem is that if you drain the battery completely, you then plug in the charger to charge the battery, the battery charge status blinks but never begins to charge. In order for it to begin charging you must remove the battery while the charger is plugged in, then re-attache the battery and it begins to charge. This is a step I find very annoying. I don't want to have to remove then re-attached the battery to simply re-charge but I waited too long and din't want to bother with the return process. It's going to die at some point anyway so I'll have to put up with this until it dies. Oh well...

Larger than the one coming with the laptop, while lasts about the same with a full charge. Worth for the price though.

I have been using this battery for about a month now and it is working very well. My Lenovo T420 Thinkpad was down to just 1 hour with the old battery.

After installing the battery I went to the Battery manager and did a battery reset. After charging it and using the Power source optimized profile, I was able to get 5:45 minutes. So far I have not had any issues so far. Definitely a good deal.

Exactly as described the battery worked as expected! I purchased this battery to replace my original Lenovo W520 9-cell battery, which lasted me several years. This battery was inexpensive and after a few weeks of use is working quite well. No issues and so far seems to go a bit over 4 hours on a single charge. Definitely pleased with the quality and longevity of the battery.

This battery got a 5 star due to it's power. My battery would not hold charge past 45 min or so. This unit is still going strong after 3 hours. What an improvement.
