Ankon G400S G500S Laptop Battery for Lenovo IdeaPad G405S G505S G510S S410P S510P Touch Z710,P/N: L12L4A02 L12L4E01 L12M4A02 L12M4E01 L12S4A02 L12S4E01 [4-Cell 14.4V 2600mAh]

Bought battery as a replacement for my Lenovo G510s laptop because original battery was lasting less than an hour. This battery works well as a replacement, lasts about 2 and a half hours before needing to be plugged in and fit perfectly.

After original battery was no longer holding a charge, I bought this laptop battery for my G510s Touch Lenovo and it works like a charm! Took old battery out, popped this one in and it fit just like the original. Computer started right up and the battery life is much longer now. Would definitely buy from Ankon again as it's such a great value.

I’ve only had the battery for a few weeks so I can’t speak for the longevity of it. I can say it fits well and functions adequately. Seems to be as good as the original so far.

Battery died on my laptop, so after doing some research I ordered this replacement. Product arrived quickly and in good condition. When I first installed it I was disappointed because the computer would not recognize it. But after leaving it in the machine for a short while and then rebooting, the computer finally recognized it and it has been working perfectly ever sense. I have not actually timed how much run time I get off a full charge, but it is much better than the old battery. I note about the seller... They have contacted me several times to ensure I was happy with their product and offered technical assistance and replacement/refund if I was not satisfied. They seem very genuine and I suspect they would provide good service if it was necessary. Fortunately, I have not had to test them on their offer.

The battery fits pretty well into my Lenovo G50-45 and looks almost exactly like the original. So far it clipped in and charged up well and I have not had issues with the computer "recognizing" it. I haven't really tested the battery life but considering my original battery was a 2200mAh, and I believe rated for 3 hrs, and this one is a 2600mAh I should expect to get 3-3.5 hrs of run-time from a full charge depending on what you're doing on the computer. As of now I would recommend this battery and I will update my review if anything bad happens within the next 6 months or so. A decent product for a decent price.

Never having a laptop before (desktop only), I wasn't aware I was supposed to NOT plug in and use battery at same time. So I just took the battery out. When I finally decided to try it again - dead! So I ordered a replacement and this is PERFECT! Fit perfectly, recognized by my laptop immediately and has a somewhat longer time to recharge than my old one. Received very quickly, packed well and very happy with my purchase. You won't be sorry!

This never worked. My laptop wouldn't run on battery so I bought a new battery (this one). It STILL didn't run on battery. I assumed it was a hardware issue. 18 months later someone talked me into buying another new battery to see if possibly I purchased a bad 1. And sure enough, I bought a new 1 from a different supplier and the new 1 worked

A great product. A perfect fit and functions as advertised. Didn't even need to be calibrated. Thank you very much. Saved the day when realized that the OEM battery could no longer hold a charge on my Lenovo laptop that's been sitting for a few years. Item was in stock and delivered very quickly. Would gladly purchase another product from this vendor
