Review on 6 Cell 4400MAh 48Wh Lenovo V570 G560 B570 IdeaPad Z470 Z560 Z565 Z570 Z575 L09S6Y02 L09M6Y02 L09L6Y02 G460 G565 V360 L09C6Y02 L10P6Y22 Battery - NinjaBatt 57Y 6454 by Eric Grayson

This is the 4th or 5th battery I have bought since 2011 for my Lenovo Z570. Fit and finisih were good. Battery slides right in unlike some other aftermarket batteries that bind a little. None of the aftermarket batteries give an accurate indicator of how much juice the battery has left. Most tend to indicate 30-40% remaining then pulmet to the battery depleted warning or just shut down the computer. Could be Lenovo software. This battery was a few dollars more than competition. No real significant performance benefits. Ninja might consider adding 3 cells for extended battery time.
