This was the correct battery for my old Dell computer. I plugged it in and it worked fine. I gave it a 3 for battery life because I have no idea how long it will last. I don't generally use that computer on battery only. But I do think I'll give it a try maybe taking in back to the patio in the morning when I have coffee and see how it works just on the battery.

My desk top computer failed to load so I fired up my laptop. The battery was dead because I hadn’t used it for almost two years. I’ve only had it for less than a week but it’s working great!

This is a no problem replacement. The swap out went very smoothly and I think maybe my laptop is operating a bit faster now. Thank you for you speedy service.

The third-party, inexpensive battery arrived promptly and fit perfectly. The computer charged overnight and booted without incident; all applications worked well.The battery needed to be charged after 3 hours. Repeating the charging cycle over several days produced similar results: 3 hours max between charges. (Not surprising, since other reviewers also commented on the battery life.)I had hoped for longer battery life, but note that the battery arrived quickly and my computer is working fine. I just keep the charger handy.

excellent product at a good price vendor went to lengths to make sure i was purchasing the correct battery for my dell laptop

I have a Dell Inspiron 5110 which is almost old enough to vote, and the original battery no longer would keep enough charge to sustain for a short, accidental cord disconnect. I found and one clicked this one, and it arrived the next day. Removing the dead one and installing this one took about forty five seconds.The replacement came partly charged and quickly accepted full charge. I pulled the cord again by accident and about an hour and a half later, discovered I still had about 68% charge on the new battery. That sounds fishy, but I'm not making it up. I accidentally needed it the day after I installed it.It is what it claims to be and works as specified.

Works perfectly in my old Dell Inspiron N5110

Product advertised at 11.1V and 48 Wh.What I actually got: 11.1V and 57 Wh.Even the item barcode sticker[which covers what appears to be the original sticker]states 48 Wh; however, the battery itself is stamped with 57 Wh.Also the product was likely somebody else's return:Got this battery at 31% capacity,in un-sealed bubble-wrap,and loosely sliding around in product box.
