91Wh MFKVP GR5D3 Battery for Dell Precision 15 7510 7520 M7510 17 7710 7720 M7710 Series M28DH 1G9VM T05W1 0FNY7 TWCPG 451-BBSF 451-BBSB

Very reasonably priced battery. If fit nicely into the slot on my laptop. Battery health field was showing "error" when my previously installed battery went dead. After installing this battery the error message cleared right away. Now the battery health display field shows as "excellent." Great product with a reasonable price. It remains to be seen how long this battery will last. My original battery lasted only 2 years and 8 months.

I've always tried to order genuine Dell parts for my Precision 7710 laptop. Let's face it though, they're likely getting a lot of their accessories from the same offshore sources as the numerous aftermarket sellers out there. However, their QC seems to weed out any defective parts before they're shipped. Dell no longer carries replacement batteries for my laptop though and so I took a chance on this particular seller. Whether I just got lucky or they do QC commensurate with that at Dell, I can't say but the battery I got was an exact fit for my laptop. It's 4 cells vs. the 6 cell original but other than that, the specs are right on. Changing it was simple enough (there's a zillion "how to" videos online). I followed the instructions that came with to precondition the battery (charge it to 100% and then allow it to fully deplete itself in the laptop) and this battery easily performs on a par with the original battery, restoring uptime on a full charge to around 5 hours (my old battery was usually dead within an hour or so of booting). Also, the laptop is running much cooler now, likely due to the easier charging of a fresh battery. I definitely would buy again, assuming this gives me the kind of life of my original Dell battery, which lasted over five years.

I purchased this product 35 days ago, and I'm very disappointed. The battery doesn't even hold a charge for 10 minutes. It indicates 6 hours when fully charged, but it drops to 0 in less than 3 minutes. I strongly advise against spending money on this product.

Not sure why this battery came with 2 screwdrivers. The Dell 75xx series doesn't need any screws to replace the battery. Maybe other models need it. The OEM battery had failed and the system was running noticeably hot and slow due to the failed battery. Once this new battery was installed, there was a definitely drop in system temperature and increased performance. The battery gave about 3-5 hours of use depending on activity. Make sure the first 2 times you run down the battery until the laptop shuts itself off in order for Windows to calibrate the usage time. The main problem with this battery is the Dell power Manager utility and its drivers do not recognize this battery. Because of this problem, you will not be able to use the Dell Power Manager to maximize the battery efficiency using the Dell custom power schemes. I am not sure how long the battery will last, but for now, it works as expected as a battery.

I bought this battery for my Dell Precision 7510 laptop to replace the OEM battery that had swollen. It has performed suitably during one week of use, and the battery life is impressive.

Battery came with a comprehensive set of instructions, how to install, how to calibrate and how to care for it in storage etc. Came in an anti static bag and nicely packaged. Followed the instructions and this morning said i was going to have 12 hours of useage given a very light work load.

Easy fit, needed to be charged as expectedHolds a long charge

---UPDATE 10/16/23---Well, this Bovekeey 91Wh MFKVP Battery is pretty much on its last leg after four months of occasional use. I purchased it mid-June. At its best, I got about 3 hours of constant use before needing to plug in the charger. As of yesterday, I got 37 minutes. More concerning is that the fan on my laptop runs almost constantly now, with only rare occasions where it is quiet. When I use the laptop on battery only, I can feel that the palm rest (battery) area is hot. The fan runs constantly. Then when I am forced to plug it back in, it’s still hot and the fan constantly runs.I am dropping my rating from 5 stars to 2 stars. I had really hoped that this battery would last, as it’s difficult to find a highly rated replacement battery for my Dell Precision 7710, which is now about 6 years old. I have resorted to eBay, where I paid a little more for what should be an OEM Dell battery.---ORIGINAL REVIEW---I am currently using a Dell Precision 7710 laptop that was purchased in 2017. After six years, I started having some problems and felt they were a direct result of my aging battery. The fan seemed to be running more often than not, and I had to leave the laptop plugged in all the time due to such a drastic reduction in battery power. Also, it was mysteriously shutting itself off, after which it required a hard boot to restart.A few days ago, I replaced the original battery with the Bovekeey 91Wh MFKVP. When installing, I did notice that the battery did not fit 100% exact like the OEM battery from Dell. When testing them both out, the Dell battery went in perfectly. The Bovekeey was a very close fit, but needed a little extra push before it snapped in.The battery was already charged 59% when I received it. I charged it to 100% and then let it drain down until the screen told me to plug in the AC power. I then charged it again to 100% and I have been really pleased with the performance after that. Yesterday, I got about 6.5 hours on primarily standby. Today, I’ve been going for about 4.5 hours at a mix of both standby and usage and my battery meter shows 50% remaining.Aside from the much-improved battery time, I have noticed that my fan is not running nearly as much, and the computer seems to be running a bit cooler. I did have one mystery shut down, but it might have been related to updates running.I am so thankful to the other reviewers here who specifically named the Dell Precision 7710 in their review. They really helped me take a leap and choose this battery. Overall, I am really pleased with it so far. I hope this review helps someone else the same way others have helped me.
