Purchased a battery that lasted less than 30 days. Email support 3x and get standard nonsense that it was tested at the factory. So far they will not honor the warranty. 30+ years of IT support and they send back a response that it "Tested working" nonsense. Plus they ship from CHINA which takes forever.

Got this from the AolsteCell vendor. Date on the box was 11/2016 (a month old). Cell checks out in HWMonitor above spec as expected. Adds 10 hours to the internal battery! Increases weight to 3.7 lbs though, but will last a JFK -> LON flight!

Love the battery life when the first time I turn it on I let it sit for awhile. Mine said 14 hours. Of course I'm not going to let it sit idle to check that #. How hard you use it , who knows how long before you have to charge it. I'm not payed enough to find out. Heck, I'm retired and don't get payed for anything.

Used this to replace the external ~22Wh external battery in my T450s and for the small compromise for a little extra height the battery life is more than doubled. I no longer have to worry about running my battery down and carrying a charger even when using the laptop to consume streamed content on sites such as YouTube. Would recommend this for anybody who has a compatible model ThinkPad. Battery worked flawlessly and came in factory sealed Lenovo packaging.

Battery arrived on time and in perfect condition.Now at first I could not get it to activate. Nick was extremely helpful when I phoned AolsteCell customer service this morning. Initially my laptop would not turn on with my new battery inserted, so I feared the worst. We confirmed I received the right battery and that I had a compatible machine (Thinkpad T440). I tried the battery one last time, and voilà, my machine turned on! Nick explained how this is a common occurrence because new hardware is not always recognized immediately. So if anyone experiences the same problem, they are advised to do a reactivation cycle, taking the battery in and out a couple of times both with and without the adapter plugged in.Nick gave me more advice about how to prolong the lifetime of the battery, advice you won't hear from Lenovo themselves because they have an interest in selling as many batteries as possible. It is best to let the battery drain to 0, then detach and reattach the battery, then charge to full, then repeat. This calibrates the battery for maximum performance and promotes longevity of the unit.I recommend the seller and I am especially excited because the new battery is rated 72 kW-hr, an upgrade over 48, which is the battery that came with my device.

Package appears to be Lenovo / OEM and the battery also appears authentic. I'm pleased with the purchase. Thank you.

Purchased for T450 - getting 16-18 hours on a single charge at 30% screen brightness with SSD installed and Wi-Fi on. The protrusion sits under the laptop, lifting the rear of the machine for extra venting. Added bulk/weight is negligible. I imagine you could eke out 20-22 hours in airplane mode at 20% brightness working in Notepad++. The stock battery is so light and thin, there is no reason to not take it as well, adding 33% more juice.

I originally gave this a one star, but then realized it was the old Lenovo charging cable that had just worn out. Got a new one and so far the battery seems to be great.
