Fit as it should, charged as it should, functions as it should. Excellent.

My Thinkpad T580 started displaying the infamous "battery #2 failure" message and was not charging fully. Under recommendation from a computer repair technician, I purchased and installed this battery. My computer now charges fully and no longer has battery error messages. I usually use this unit as a desktop, so I cannot attest to the actual battery life at this time, but so far it is working excellently.

Holding a solid 2 1/2 to 3 hour charge at least with full usage. It brought my 2017 MacBook back to life. Took me and my wife like 10 to 15 minutes to swap out the battery the kit that was provided worked perfectly.

This battery worked perfectly as a replacement for my MacBook Air. Installation was straightforward and the laptop recognized it immediately. The battery life is solid and it holds a charge well. Overall, a great option if you need to bring an older MacBook Air back to life.

When my laptop battery stopped working, my son went to a computer store to buy another battery, and after he replaced it, that battery didn't work, and he had to return it. The computer store did not have the correct battery for my laptop, so he found this one. He replaced it, and it works perfectly in my laptop. It was easy to install and saved me money. Glad that Amazon had the correct battery.

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.

Replacing the old was good and it restored the laptop back to life

I don’t even know what to say. I got the battery and connected it. Didn’t take me long and it was simple. My problem now is that (I had also purchased a new charger) when I tried to turn on the battery it said it’s dead. I plugged it in and turned it on because I needed to know the battery percentage to do the calibration. Charged it to 100% as the instructions said it needed to be first fully charged. Once it was charged and was drained to 20%, it would not charge (it showed charging and there was lights on the cable but it stayed at the same percentage. I had to reset the SME to get the battery to recognise the charge and vice versa. It started to charge. Then I did the second drain I left it at 20% and had to go on the road so I didn’t plug it in. I just got home and the battery is dead. I had to again reset the SME so the battery can recognise the charger. I had tried the charger on the previous battery before I got this one and I didn’t have a problem. I must say with the new battery the charge is longer, the battery stays charged longer and the MacBook is moving faster as well which I love. But why do I keep having to reset the SME just for my charger to be recognised.

So far so good

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.
