TechOrbits Laptop Battery for Dell Inspiron 3420 3520 15r 17r 14r 13r N5110 N5010 N4110 N4010 N7110 N3010 M5110 M4110 M501 M503 Series, Fits P/n J1knd 4t7jn - 3 Years Warranty

The product seems good so far. On the plus side, it took only one complete discharge before the battery charged to its full 100 percent. On the minus side, the first battery charge lasted only about an hour and a half – even though the battery icon on my computer said that I had 3 hours and 45 minutes left when I pulled the plug and went on battery power. I hope I'll regularly have a longer charge life than that. Even so, this battery is still much better than the one I replaced, and a very good value.

Buena batería

So far so good. Came faster than expected, charged right up, and I'm using it right now. If I have to get another one, I'll pretty much come right back here, and if my ASUS needs another battery, I'm hoping to be able to find one these folks!

Its a good replacement for the price you pay compared to one from Dell. The battery doesnt hold the charge as strong and long as the original battery but at least it holds a charge. My original needed replacement.

Perfect fit. Tested with a full charge with battery, dimmest screen setting with no screensaver on a newly installed windows 7 system with no drivers installed. Leaving laptop idle, got about 1.75 hrs until the 7% critical battery alert. I would expect less for actual usage, with brighter screen, wifi, higher processor use, etc. Warranty is a plus!From an IT Consultant

This battery works great. We've had no issues with it. We bought this the same time we bought an SSD for the old Dell, and between the two, it's a new machine.

Fits and works well.

Works better than the one it replaced. Seems to work efficiently. Haven't noticed any dramatic drops in charge.
