Fancy Buying FV993 M4800 M6800 Laptop Battery for Dell Precision M4600 M4700 M6700 M6600 Series,Fits RY6WH FJJ4W KJ321 PG6RC V7M28 R7PND 0TN1K5 7DWMT JHYP2 K4RDX Laptop [11.1V /7800mAh/89Wh]

Battery works great, but there may be a driver configuration at play.The battery works very well. This was not my initial impression, as the battery at first would not take charge. It turns out that the main issue had to be with a driver configuration preventing the battery from charging. The youtube video:"Laptop Battery not charging "plugged in, not charging" Easy fix" describes how to remove the battery driver(s) causing the problem.

EASY INSTALL, WORKS GREAT!

My laptop tried to boot, but failed to do so. After removing the battery, with the power supply plugged in, the laptop would boot and run. The battery was the problem (also indicated by its very short and diminishing ability to power the laptop. This replacement fit well, and corrected the problem. Now I can use my laptop without having it plugged into a power supply again. At this price point, I'd even consider getting an extra to charge up and carry if you tend to use your machine away from a power outlet very often.

Bought this to replace the battery in a 2017 laptop that would not hold a charge anymore. The battery was very well packed, with anti-static materials and even included a plastic pry tool to remove the plastic covers on the back of the laptop. The battery charges fast and does an excellent job holding a charge. I would highly recommend this as it is a great value!

Worked great at first, held a charge for maybe 2.5- almost 3 hours in a HP Elitebook but 2 months later and it only lasts 30 mins when unplugged and worst of all, my computer doesnt register that it is almost dead so it just cuts off unexpectedly. Would not buy again or recommend this product.

Delivered on time, fits the Toshiba Satellite and charged. Proof will be how long it lasts....

I used the battery as a replacement for the dead one in my Lenovo Yoga. The computer can now turn on, but it charges a little strangely. Sometimes it will charge up to 100%, sometimes it will only charge up to 77% before stopping, etc. I would've taken off two stars but my laptop is old so I'm not 100% sure if it was the battery's fault. If you're looking for a cheap option so that your laptop can actually be unplugged for a little while, this is a good bet for $21 (when I purchased it). However, if you want something that will bring the battery back to new, I recommend looking somewhere else.The install was fine and they give you a little screwdriver and plastic squeegee.

Fit & works in my OLD Asus GL-502V Laptop without any issues. For under a $100 we replaced a worn out battery, added more memory, a M2.SSD and Linux so now the old laptop is somewhat useful again and runs way faster than newer Laptops.
