I only had one issue with the battery and it is NOT the fault of NinjaBatt.Lenovo in their infinite wisdom uses IC Chips to identify parts used in their computer systems, however, once their machines are no longer serviced (obsolete), The Bios Writers do not send out an updated BIOS to switch of the identification switch, which then still then prevents third party parts being used properly or at all. Unfortunately (NOT NINJABATT FAULT) once the battery had used its power, the Laptop would not…

The battery came earlier than expected, and had a 75% charge when delivered so I could get right to work on the road.Kudos!

wonderful battery -- fit just right and with the extra cells beyond the original, the extra working time is great. It lifts the back of the laptop higher than the original and provides a nice angle for typing. All-in-all, it is better than the original!

Thank you for providing a great replacement Laptop Battery. Have purchased these in the past and always completely satisfied. GREAT Price also!

Wow, fast customer service. Ordered battery, but it was not holding charge for very long. Called them and I had a new battery on my porch two days later.

Has been powering my Lenovo IdeaPad Z570 for over a year. Now I am getting like 40 minutes to over 1 hour runtime. Thanks for attention.

So far so good. Seems to last well and only shows signs of reduction when using DVD drive etc. Much better than others I've tried.

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…

The battery works but it doesn’t fit perfectly. So, a good jostle shakes it free and shuts it off in the middle of whatever I may be doing.

Just got this from UPS. Easy to slip into my laptop and had 3/4 charge already! Happy with this product so far! Thanks for attention.

the OEM part. Thanks for attention. Expect about 2.5 hours from a full charge. Not terrible for an older 15-inch display laptop.

I had no idea I could buy a battery for so little money. This old widow replaced it in 5 minutes and I'm back at my laptop that I was going to toss. Excellent value and quick arrival!

- Ran a Windows 10 battery report: Design & Actual charge matched at 48.8 Watt Hours.- Tested battery life by streaming a 720p video over WiFi: 2 hrs 30 minutes to 10% charge (disabled panel dimming).- Excellent fit. Battery slides in & out easily without having to fiddle with it. Securely locks in place.Tested on a G560: i5-560M CPU, 8GB RAM, SSD, 15.6" Panel. Your mileage may vary.

So far so good, our old battery barely charges. This new one holds for about 3hrs on a full charge before we plug it back in Thanks for attention.

I had two of these, the first would not allow the battery latches to snap closed because it was just a wee bit bigger then the original so the seller sent me a second, it didn't fit either.The computer was a Lenovo. I ordered a different brand and that fit perfectly.Can't say if the battery was good since it never fit the machine.
