Very good battery. Lasts 9h for me in document processing and web-browsing

A really good quality battery, however what sets it out from the competition is the very clear instructions on getting it optimised for calibration etc.

Measured the battery capacity with tlp on my Lenovo X230 laptop and it exceeded the advertised value. The battery is made with good quality Sanyo cells. I can easily do a full days work running on this battery. Excellent product, buy with confidence.

Clear instructions on how to manage the battery for best performance. Appears to be a good quality product. Excellent all round.

Excellent product. Battery arrived on time and seems to have a good life.

A very good replacement, it keeps its charge well. This means my laptop is no longer a desk top and can be used without the need of finding somewhere to charge it all the time. I'm very pleased with this Duracell replacement.

Good battery charges well. I get a full recharge in two hours. On a full charge I can average 5 to 6 hours of normal use without dimming the screen and stuff like that.

My laptop was almost unusable thanks to its worn out battery. This replacement battery fit the laptop perfectly and gave it a new lease of life with an above-8 hour battery life. And for a very reasonable price too!

I am very pleased with the battery. I previously bought a cheaper alternative but the battery life was very poor. This battery performs very well. It protrudes slightly from the back of the laptop because it has extra cells but you can tell it is good quality because it still fits in the docking station.

Very happy to find this battery is genuine. The instructions/advise included were very useful & I am now getting a good 7 hours out of my thinkpad!

Works OK so far
