My daughter needed a higher capacity battery for school so she can use it all day without a recharge. She has a refurb'ed Lenovo X250 SSD. The battery change is easy and it stands up from the base a little but is not to steep to make it uncomfortable and runs about 75% the length of the laptop. The battery is not overly heavy as a key feature of the Lenovo X250 is the compact, rugged and lightweight nature of it.The battery capacity is impressive, I got 13 hours out of it with only a few sacrifices in power management and was able to eek out to an impressive 20 hours with some screen brightness changes and some peripheral power settings. I did not want to make it impractical for her though, the laptop needs to go into 'sleep' between lessons. 13 hours is more than enough.My guesstimate is it'll take about 3 1/2 hours to charge it from 0% while the laptop is in use.The product itself is very well made, fits the laptop like a glove and is manufactured with the identical plastics and has the same standards and product certifications as the original battery. No reason to think it will not last a long time and give a good account of itself.

Battery arrived today and so far I'm thrilled that it's exactly as advertised. I have had a few batteries over the last few weeks for this (made the mistake of thinking the slimmer ones would suit my T450 better but the battery life on the 23w ones is shocking, especially since two of them only charged to 23Wh - NOT from this supplier from another brand I might add!)So when I decided that two of the 23wh ones was a terrible idea I went looking for the best reviewed battery I could find. Thankfully a few people had posted screenshots of their linux battery management showing the full charge etc so I went for it. We'll as per my picture it does exactly what it says on the tin.It took Power Manager a little while to figure it out, it only charged to 85% and then said 6 hours left till full charge but a few reboots and it was playing ball.So yeah, so far so good everything looks promising, numbers are right, capacity is right.. Time will tell on the rest!

While using this battery, laptop limits itself to 399mhz and basically becomes unusable, as soon as you remove, laptop cpu boosts as usual, so I’m guessing it isn’t able to deliver the power/voltage that the laptop needs to work properly

Had this battery for a few years now and its still working as it did when i first got it.Revived an already old thinkpad which is still my main computer.I have upped the stars to FIVE

It does give longer battery life but not as much as I expected

When I initially received the battery I had a few issues where it was not charging to the capacity stated, however after contacting the seller and exchanging several emails (all to which have been responded to in less than 12 hours) I was arranged a replacement. Today I have received the replacement and it is flawless. I can't express how pleased I am with the service that was provided, but also the long lasting battery.

Using lenovo diagnostics utilities to run tests, the capacity is as described, this in conjunction with a new internal battery, on battery saver mode i'm looking at 30 hours battery life on a single charge which is unreal, and around 7-10 hours in full performance mode on a single charge when needing to do rendering or CAD Design etc. High quality too, without a doubt probably comes from the same factory as the genuine Lenovo branded version.

And just like that... It stopped charging, it's currently stuck at 44%.. What a waste of £45
