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 Kory Shelton

Couldn't rate this battery for "life" but I expect it to be a good performer. The key element for me was fit. You probably know, if you think you need a new battery, an exact fit is most important. The price was excellent. It arrived in excellent packaging and was brand new. As is always the case with products originally designed by IBM, now Lenovo, battery removal and re-install are very simple and positive. No guesswork about how it connects. The number on the left bottom corner of my screen was B575. While this number didn't match the list exactly the, shape and length & width looked like a match. Check your numbers, if they are a "go", NinjaBatt appears to have a very good product.
