LQM11.1V 97Wh 9-Cell New Laptop Battery for Dell Precision M4600 M4800 M6600 M6700 M6800 PN:FV993 FJJ4W PG6RC 7DWMT JHYP2 K4RDX KJ321 R7PND RY6WH

I ordered this battery for my Dell M4800 laptop on Amazon. It arrived quickly and was securely packed. I placed it in my laptop with no problem. It is exactly the right size and popped in with no extra effort. My laptop is loaded with 2 hard drives and this battery still holds a charge for hours. I have been using it for almost a month now and it works great. I am very impressed with this battery and definitely recommend it as an inexpensive, top quality alternative to buying a branded battery directly from Dell for three times the price ($149.99 on Dell website). This battery works as good as or even better than the original Dell battery did.

The battery was a plug compatible replacement for the original battery that came with my Dell M6600. Has been working perfectly since receipt the past month+.

Has worked great and was easy to install. Holds a nice charge. Temperature is ok. Laptop is around 9 years old but I had upgraded memory and added ssd drive. Was purchased for software development. So, good i7 and spec’s. Good secondary machine.Battery needed replacement, so after researching bought this one. Very happy with it.Only issue has been it appears to be a bit insecure in the bottom slot. I’ve had it fall out a couple of times. Not sure if locking mechanism not tight enough or battery is slightly small and moves around.

I bought two of these batteries. One for my computer, one for my wife's. I installed both of them soon after they arrived, but was unable to give them a full workout until recently. The reason for the delay is that both our computers pretty much lived 24/7 plugged in to the chargers. My wife would unplug hers for about an hour at a time to do home school stuff with our granddaughter, but a one-hour gig is not enough to give a battery a test for how well it works.But now we are just finishing up a 17-day trip, and I was able to give my battery a really good workout, test, and evaluation.There was one day when I had to fire up my computer three different times (meaning had to start it from a complete shutdown). Each time, I browsed, did emails, and did some photo transfers and editing, for about an hour each time. In other words, I used the computer, totally on battery, for about 3 hours 20 minutes, including 3 startups-from-scratch and lots of interfacing with a wireless network.When I started the computer for a fourth time after those three sessions, I looked at my battery meter, and its said 43% remaining, estimated 1:42 time remaining on the charge.Oh, yeah, that's what I'm talking about! That's the kind of battery life I'm looking for, that I want to have when I travel with my computer.If I ever have to order a battery for this computer again, I would definitely buy this kind.

JUNK 2 months after purchase holds charge for 5 minutes I wish they had no stars

It arrived quickly, and it was well made. It fit my laptop perfectly, just like the original battery. I haven't really given it a real test, but I did put my laptop in sleep mode and left it like that for two days. It had lots of charge left for me when I woke the computer. My old (original) battery, if you left it like that, it would have died in a day. I'll try to give a really challenge soon, and will put my findings here, if I remember...

So far, so good. Charges, holds my M4600 under load (as opposed to my last battery that wouldn't). Time will tell. If I have trouble with this battery not holding up in coming months, I'll update my review. This is my 3rd replacement battery on this laptop (not of this brand/seller). First one lasted just under a year, 2nd one was never right & was returned.UPDATE 1yr later... This battery is still holding strong, even after my laptop decided to power on in the bag a couple times, run itself up to 780,000 degrees while running the battery completely dead (Thanks Microsoft). I don't run this laptop on battery often other than to hold sleep mode over a weekend or an occasional run without AC power, but it's been doing that just fine, which is MUCH better than I can say for the other replacements I've gotten, and is beginning to border on as well as the original $200 Dell battery

Purchased one of these batteries which turned out to have a bad cell and wouldn't fully charge. Filled out a return through Amazon and had a new one in two days - which works fine. If it won't fully charge, return it :)

Received quickly, great price works as expected
