It worked great and arrived so quick.

Worked great!

The battery for DELL 5110N fits exactly in to the laptop. Life between charges looks Ok.

Arrived promptly and works well.

Update!So, I exchanged my battery, and the new replacement battery works amazingly well. Charges at a good speed, I was able to get several hours of video playback (I got 2-3 hours and a fully imperfect test) on a full charge, and the battery retains it's charge, all the while working in my bios, and giving me a great fresh battery experience. I do not know if it's as good as the initial stock battery, as I'm simply not setup to test that, not would I have results from 4 years ago available, but 2-3 hours of video playback on performance settings on a full or near full battery is fine. That means I can get some good usable time with the laptop doing non-gaming things while on battery without any real worry.The other aspect of the story is that the company did reach out to me based on my feedback to ensure I had a smooth customer experience, which is great. That lets me know that they care about the quality of their product. The exchange went super smooth, and I'm a satisfied customer.So, with a working product, I was going to bump this up to a 4 due to having an initial product failure, but with their customer service and given the issue may be only something I found as a power user, I'm bumping my review up to a 5 star.Pro Tip: In your device bios, you can set a setting to enforce a charging limit on the battery. Most experts and the device itself will recommend you set this to 80% to help extend the battery. What this does is prevent the battery from charging much beyond 80% for a "full charge". Why would you want to do this? Well, being above 80% or below 20% for long periods of time is not good for most Lithium Ion batteries, as is constantly charging them when they're near full. This is why many devices have a 5-10% threshold where they stop charging even when plugged in, so why your phone may drop to 95% quickly after being removed from the charger as it's protecting the battery from overcharging. So max charging at 80% gives you some extra headroom to not charge it against the danger zone, and can save your battery longevity in both capacitive charges as well as adding years to the battery, and preventing battery expansion.New Conclusion: Company supports it's product, and the battery I have now meets or exceeds my expectations. Highly recommend.Old Review: Needed a battery for my Omen 15 gaming laptop. Was a pretty easy install as I've cracked it open before and knew exactly how to. Bios recognized the batter right away, and Charging took a while, but eventually got to near 100%, and I was happy, or so I thought.The issues:1) It took a LONG time to charge. Like 20% charge while on took 2 hours+. I initially thought this was due to just being tuned, and honestly, since I use the PC mostly when plugged in, it wasn't a huge issue. But...2) The device loses a charge slowly. I had it off for over a week and it was dead. I didn't notice it much between a few days, but over a week and no charge from an 80% charge is not acceptable.So, why 2 stars? Well, 1, for some this may still be usable. If I was driving it every day, it might be just fine. And 2, They let me exchange it, so we'll see if the replacement batter works, or if I have to try to find another option.

Not worth it. Fully charged the battery, unplugged it, and after just 1 hour on standby, with no usage, it had already dropped 30%. I let it drain completely, recharged it, and repeated the test with the same result. This battery does not hold a charge.

This battery refreshed my Dell N5110 that was otherwise going to the landfill. Excellent tolerances and fitment.I was initially going to try and rebuild the old battery--but at this price point, AND with an upgrade from the old milliamp-hours rating, it was a win-win!

Great replacement batteries at an affordable price. bought two for identical laptops, charged up well, hold their charge well.
