9JRV0 Laptop Battery Replacement for Dell Latitude 5521 5531 Precision 3571 3561 3581 3591 Alienware M17 R5 M18 R1 R2 Series Notebook 05RGW 005RGW 53XP7 053XP7 97Wh 8071mAh

It was reasonably priced and pretty easy to install. Tools needed were included with the battery.

Sufficient replacement battery, came quick and fit correctly.

My tablet battery has already been depleted. I can only work on it without power adapter for 30min. So, I have been using it plugged all day, which made it like a desktop computer. Upon realizing that, I bought this replacement battery and I am now able to use it as a tablet on-the-go.

It was pretty easy to install, and it does the job. It was compatible, but it was very slightly different from the picture provided, which might have been a newer/older model.

I had purchased the same battery from another vendor's website, the battery turned out to be defective having less backup than 2hrs. I purchased this battery for my Thinkpad yoga and I get 5+ hrs, very satisfied with the product and purchase value.

Worked fine, just didn’t end up needed it after all.

So far so good, holding charge, no problems thank you

Was hoping to gain the original ~5+ hr battery life by replacing the battery as the laptop still works perfectly. Using this battery only yeilds 2~3 hrs tops. 2.5 is pretty average, and all this thing does is lite surfing. NO photo/video editing etc.Even though it's a lithium battery, I did cycle it down to dead and full charge many times. Purchased Aug of 2020, it's late Nov 2020. Just kept forgetting to write a review.
