This battery is easy and quick to install, and the impact of its additional size and weight are far exceeded by the tremendous gain in usable time on the laptop. The original battery is still usable and should be kept as a backup, or another means of squeezing out a few more hours of computing time if your on really long trips or flights. A good buy.

More power (run time) than OEM battery. Battery failed in less than a month, replaced under warranty. Replacement has been working great.

this adapter is fully perfomed in my laptop. when it was installed into my lsaptop, it was cery compatible. i compained that it took long time for receiving.
