This battery arrived quickly. I plugged it in and had no issues with the charging of it. I have had it only two weeks, and all seems to be running fine in that time. I have not tested the full time for the battery yet, but expect it to be okay.I also liked that there wasn't too much packaging around the battery like I can sometimes get. The box was appropriate size. the protection wasn't needed as the battery is pretty robust to shipping issues.

Price compared to an official Dell Battery is incredibly good. Hours of battery life are fantastic!!! Before on the old smaller Dell battery my computer wouldn't last 30 minutes without being plugged in. Now it goes hours. I was skeptical because it isn't OEM but the performance is great.

Impressive, battery gives 4-1/2+ hours of continuous use, pretty darn good for this 10 year old core i5 laptop. Will probably still be working when Microsoft forces me to drop this perfectly working,, lightning fast machine into a landfill b/c they won't allow win 11 update. As such, I'm shopping for Mac now.

Bought this in May 2018. Would not take enough charge to boot laptop in September 2019. Contacted seller and had a new replacement on the 18 month warranty in 3 days! I can't say enough good things about that kind of customer service! Replacement took a full charge and laptop is working fine again. Hopefully this one will last longer, but this seller is definitely reputable!

This battery is exactly what I needed for my older E6510. I plugged it in and it charged up with no issues. I ahve ran it two day now for about 2 hours each and I am only down to 54%. Perfect!I will drain this to 5% and then recharge again. I will do this a couple of times to get the battery "broke in".Thank you Ankon Direct for making a great battery at a reasonable cost!

I bought this 2.5 months ago. Worked perfectly at first. Held charge extremely well when it worked with no problems at all. That's the only reason it has one star.Anyway, suddenly it stopped charging anymore and my return window is closed. Not buying this make again and would not recommend.

I bought this battery for my Dell Latitude E6410 with the intent of carrying two batteries and swapping them out and I was pleasantly surprised that this battery had a longer life than my old battery, and so thus far, I have not had to swap them out. This battery lasts >2 hours on a laptop running Ubuntu with light browser and word processor use. Ubuntu has given time estimates ranging between 3 hours and 9 hours depending on what I've been doing, but I don't actually use my laptop enough to be able to confirm those numbers. It's a nice battery.

Works great with my Dell Latitude E6510. It's an old computer and I was concerned about possible charging issues. All good with no adjustments needed to the charge cycle.
