It performs as specified. It actually allows your laptop to be portable as it should be. Lifespan unknown at this time.

although it might not be too good for those who wish to play games while in battery mode. I do not play games, so I am satisfied with it

Battery works well with my laptop. I strongly recommend this seller and appreciate their strong commitment towards customer satisfaction

buy this batteRy to replace my 3 year old battery. Laptop is still in good shape except for the battery. Now it's better than new since this battery lasts longer than the original one did when it was new!

Good replacement battery for my Toshiba tablet. The old one held less than 15 minutes charge, after 3 plus years of use. This replacement was about a third the price of the Toshiba OEM replacement and is an excellent substitute. The color is a bit lighter than the Toshiba battery, but the fit and the power storage are similar to the original's as it was when it was fresh. Seen that other reviews suggested that Toshiba's replacement battery is not distinguished by superior durability, I saw no reason to pay a large premium for it. This replacement has had only a few weeks of use, but thus far it is holding a good charge

this item is very satisfying. i foud this website by chance,while it now provide me convenience . thanks a lot.

a very solid replacement battery. I WISH THIS BATTERY COULD REPLACE MY OLD ONE,NOT JUST AN ADAPTER.

this item works just like the original, I mean, its compatible with all the software(battery saver, and charge light.) I was worried at 1st b/c it read 100% charge but the charge light was still yellow. I used it and next time I charged, it turned the charge light blue indicating it was at 100%. Pulled it out let it set for a couple weeks, next time I put it in it was still 100%, excellent.

The battery works perfectly and extended the life of my Toshiba Satellite to 2.5 hours (and currently still going...)
