Perfect fit in my Lenovo laptop. Easy to install, was about 85% charged out of the box. Charged up quick to 100%. Holds a charge for approx 3.5 hrs under moderate use. Totally happy with my purchase.

perfect fit for my Dell Inspiron. 5408.. Holds charge very well.

I wanted to sell my ASUS L510 with a bad battery and decided to replace the battery rather than dropping the price to pocket change. It was an easy fix on this model and the battery functioned as expected. Now I kinda wish I would have kept the laptop since the new battery gave it new life.

Bought this to refurbish and upgrade my new-to-me Thinkpad T470. Installed quickly and easily, Hardware and OS immediately recognized the battery and began charging it. So far has held charge very well and was a great value to add the second battery to my Thinkpad. Very pleased with the results so far.

Overall, very pleased with this inexpensive yet well constructed replacement battery. The enclosed instructions were pretty much useless. They were generic and didn’t actually apply to this battery. However, it is not rocket science to remove the back laptop cover and the four additional screws to remove the legacy battery and place this new one inside. I was a little concerned about any bios updates or software changes that would be needed, however, the Lenovo computer very quickly recognized the new battery, and seems to be providing a whole lot more storage charge than the older OEM battery that was replaced. Overall, for this price, this is a really good choice. Would have given five stars if the instructions were more clear. Since this is a specific battery for this model, there really isn’t a good reason not to provide those.

All good as expected

Up and running fit the laptop price fair

well i put it in about a week ago, and seems just fine, have power cycled it a couple times. so far good

Excelente llegó bien empacada, enbono perfectamente a mi laptop, reconocio el sistema la batería sin problemas, me dura entre 3 y 4 horas de uso, lo único mal es el manual en inglés la recomiendo

Pues se ve como nueva, pero después de cargar la batería y drenarla como indica el manual para calibrar la batería, no dura la batería más que una hora, lo mismo que mi batería que reemplaze. Si buscas algo mejor, recomiendo busques lo original, ésta opción NO es buena.
