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 Review

My Lenovo G780 computer, purchased in 2012, started to show signs of decreasing battery capacity. After a thorough research on Best Buy for a battery to replace the Lenovo L09L6Y02 and I decided on this NinjaBatt.As soon as I received the new battery I plugged it in and I let the battery charge for over 2 hours. Then I powered up the computer and as soon as I logged in I was presented with a message from Lenovo Energy Management saying that the capacity of the battery I am using is now 40% of…

The battery fit my computer perfectly and was already charged. Arrived very quickly and was less expensive than I had expected. I wish I’d bought it sooner.

I’m impressed. My experience with generic laptop batteries has historically been poor. So far this has performed extremely well in my Lenovo G780 laptop. Plenty of battery life, consistent charging, has active life better than I remember with the original battery. Very happy so far, I hope it lasts.

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…

This is about the product. The company is great honoring their warranty, but in 8 months, I am on my 2nd replacement (3rd battery). It lasts okay for a couple months, then peters out. One instance I had a full charge, and in 20 minutes it had 70%, and in another 15 minutes it warned me to plug in and charge. Also, installing is very difficult and is so tight you have to pound it into place (all 3 of them). I am not sure how this battery had a fantastic rating, which is why I bought it, but the…

The shipping and delivery was great. Battery life is a terrible question on the questionnaire; there are so many variables, and we just started using it.

This battery brought my laptop back to life. Battery life is great, seems to be as long as the original battery when laptop was new.

A few years back I purchased a different battery from a different source. It never fully charged, couldn't use the computer unless plugged in. Thought it was an internal problem. Got worse so I decided to try.Now I kid you not. It charges. Stays charged. And I swear it's faster and brighter.

I had not used my laptop for a long time, so I may not remember previous battery life, but it seems like I am getting less life per charge.

This is my second review of this item. On the first review I wrote that I get about 1 hour and 45 minutes of battery life. Now that I have had the battery a while the battery life has gone up to over 2 hours. Very pleased

I received my battery over a week ago. My laptop has been unplugged for 1 1/2 weeks with an average of 1 1/2 hours of use per day. Battery is still going strong. Time will tell but I am very happy so far.

It was received promptly and installed easily. I’ve not yet used it long enough to say anything about its duration in my laptop but I’m anticipating that I will be fully satisfied.

This was my 2nd try. the first seller's product arrived in an open bag and didn't work. This Ninja batter was in a nice, sealed box and worked right away! Not sure how many hours it lasts, but happy to say I trust the product.

So far I'm happy with this purchase, it shipped fast, it was the correct fit the first time. And it seem to hold a great charge.

This battery provided the direct fit replacement for the original battery. No surprises. Received quickly with no shipping damage.

You should include installation instructions with the battery. It is easy to install, a simple unplug the old and plug in the new. Nothing to remove. It charged to 100% in minutes. If it lasts and at this price it a steal.

Battery works great. Purchased for Lenovo Ideapad Z570. Instillation was easy and so far the battery is working well. Thanks for attention.

This battery was easy to install, came with a light charge, and charged quickly and held the charge for a good time. Thanks for attention.

I had an old Lenovo laptop that I converted to the Ubuntu OS. The battery would only last a few hours, so I replaced it with this one. My daughter can surf the web for 8 hours with this battery!

Unlike the experience of some purchasers, this battery was very easy to install and fit like a glove. Right out of the box it showed 80% charge and after a little while with the charger it went up to 100%. Leaving the laptop on for several hours, idle not in use, the battery still showed >40%. I am pleased so far.Update: Battery is completely dead after less than 90 daysJunk!
