This replacement battery is a perfect fit for my Dell laptop and works just like the original. It holds a strong charge, giving me several hours of use, and charges up quickly without overheating.Installation was simple, and I like that it comes with a 12-month warranty for peace of mind. The build quality feels solid, and so far it has been very dependable.Overall, this is a high-quality, affordable replacement battery that restores life to older Dell laptops.

Just received my replacement battery for a Dell Latitude. The replacement came with screwdrivers to remove the laptop case and a plastic wedge tool to help open the case if needed.Battery provided was the exact size as the oem, and was easy to install after removing the original. The laptop powered right up without the power adapter - just the battery, as they suggested it should be done. Showed up with 68% charge on the battery. The instructions were helpful, showing how to manage the charge by letting it drop to 5%, then charge to 95%, etc. for the first few cycles.For the last two hours two I've been running updates, scans and other power intensive tasks. Battery status shows the battery draining very, very slowly. I'm only a couple hours in, and am happy with the purchase. Hopeful this will last several years. Looks like it has a one year warranty. Great price compared to oem!

Easy to replace the battery, when following existing videos on the internet.Battery worked without a problem and charged back to 100%.Btw, Dell doesn't seem to sell replacement batteries of that type anymore, so you have no other chance than going third-party.

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.

Installed the battery and followed the charge and discharge instructions which was a pain and took a couple of days to complete but now my laptop runs for hours. It’s awesome to have a fresh battery. The old battery was swollen and probably close to causing damage and I had no idea until I opened the laptop to replace it. Glad to have it done.

Nice Battery, works perfectly, last for hours 3+ u recommended

Died after a few cycles. I don't use the laptop much but I would guess maybe10 boot ups since installing. Worked great at first, then no juice after a few minutes to the battery is no longer recognized.

Excellent battery. Tools were perfect for the installation. I charged it up and it's been going strong for 10 hours so far. I plant to do 4 cycles of depleting and charging before I leave it plugged indefinitely. Very happy with this purchase. Price was very fair.
