Excellent battery!
Works as-advertised! My aging laptop’s battery life has improved drastically since installing the battery. Just make sure this is the right battery before you buy otherwise it may not be compatible.

Works Perfectly—Several Hours of Charge
After about five years with my Dell Inspiron, the original battery stopped holding a charge. I replaced it with the 42Wh YRDD6 battery, and it’s been fantastic. The installation was simple, and the battery immediately performed like the laptop was brand-new again. I can now unplug and work for several hours without worrying about running to an outlet. A solid replacement option that restored my laptop’s portability.

Thank goodness it works.
I took a chance based off other reviews and I wasn't disappointed. I've gone a 2017 Inspiron Dell and it's a great computer but the batter took a dive, and so did the cord. I couldn't find a new replacement anywhere else. And Dell doesn't even carry it for my lap too. This did the trick, fit perfectly and came.with a charge. So far the battery life is holding up to about 3 hrs of constantly using it. 4 hrs starts to drop bellow 40%. (I'm using an intense illustration program) Fast charge. Great price! We will see.how long it last!

It fits and it works. Harrowing to install, though, on a Dell 7577.
My Dell Inspiron 7577's OEM battery life had dwindled to something like 15 minutes after 3 years. Dell's price is well over $100 and I'm relatively handy with computers so I didn't have a problem buying an aftermarket part, especially as other ratings on this particular item were pretty good. I downloaded the repair manual for my laptop, and as soon as this battery got here, went to replace it. Taking the back off a 7577 is easy. Removing the screws that hold the battery in place is easy. Removing the CONNECTOR from the old battery (to be able to connect it to the new one) is nerve-wracking - seriously, those are the thinnest, most FRAGILE wires and connectors I've seen. If you do this, DO NOT PULL ON EITHER CONNECTOR (the end that fits on the computer as well as the one that fits on the battery). I used the point of a HAND SEWING NEEDLE to gently pry both ends of the battery cable free - very slowly, a nudge on one side and then again on the other, until it was far enough off the pins to be able to lift it off the rest of the way (GENTLY!!). Putting it back on the new battery was the reverse - fitting it gently onto the pins and then pushing one side, then the other with the eye of the needle. I had to take off BOTH ends of the cable - the computer connector and the battery because the wires are SO thin, I did not want to flip the cable over (the connector is on the side facing down, of course, so you have to flip it if you don't remove the computer end first). I was seriously afraid I'd snap the wires if I did flip it over. Once both connectors were in place, screws back in and the laptop's back put back on, the system booted without incident. The battery did not have a full charge, and once I charged it I ran the laptop till shutdown three or four times, to condition it. It currently holds a charge a little over 2 hours (not much different from the original OEM battery), which I'm pleased with. By the way, the screwdrivers this ships with? Don't need 'em for this purpose (a small Phillips head is fine), and they're pretty cheap/chintzy anyway. The battery seems to do what it's supposed to, and I'm happy with that. Vendor shipped it quickly and followed up with a warranty email.

It came the tools to install and it was a perfect fit for my 5410 2in1. I will test the battery and edit my review after a month. But it looks promising for the $40 I paid for this.

Tips to remove difficult battery screws
So far the battery is working fine but I want to share with you a challenge I faced if you run into this situation The Seller provided two different screwdrivers that have always worked for me to remove the screws in the battery. One is like a phillips head the other is more like a Torx type screw head. However, by laptop had a screw head I have never seen before and I have replaced batteries in 3 different laptops this last year. If you determine you cannot remove the screws without stripping the heads here is a tip I used. First, use a rubberband as wide as screw head. You use either one of the screwdriver tools (I used phillips) they sent and push hard on the rubberband and the friction or grab of rubberband can lossen the screw head. The additional step was using a small folded up square piece of alumnium foil that will accomplish same thing to lossen the screw but rubberband option worked the best. It took me a some time to get this replacement done. If you do strip out the screw head and these tips don't work you can order an extractor tool. There is no way for Seller to know what screws they put in these laptops, but they try to give you a couple of options to remove the battery screws.

The battery arrived on time and was simple to install. I've had this battery installed on the laptop for 3 months now and has worked flawlessly and got me through a couple of power outages. I would recommend this battery when a replacement is needed.
