Is it compatible with ALW x17 ?

The x17 (R1) uses an 87 Wh battery, not a 99 Wh. It's also a quarter inch thinner than the 17 R4 I have. I'd recommend verifying the specs of the x17 (don't know if you have an R1) and finding a battery that matches your specs. If you're comfortable with disassembling your laptop to install a new battery, you should go ahead and open it up to check the part numbers and specs on your current battery. If you don't mind running on no battery for a while, I believe you could remove it and close it back up to use while plugged in.

My original battery was 68 Wh (model 44T2R) but this one is 99 Wh is it safe to replace the old one with this one?

Yes. It is just a larger store of power. My laptop is fine. The battery tends to run a little cooler too.

Alienware 17 r5 need a battery, 99whr, 6 cell, lithium ion part number 01d82 your part number9njm1 is an updated one --cross reference please?

Dear customer, thank you for your question. YES, this 99Wh 9njm1 battery will work for Alienware 17 r5, replace with part number 01d82.

Will this work for an Alienware 17 R5 without any issues?

It is advertised as fitting a 17 r5 and the Dell specifications for a 17 r5 include this type. I do not know if Dell had two different r5 cases, where one can only take the 4-cell model. You should inspect your laptop to see if you currently have the 9NJM1 battery type, this will help confirm that this battery will work for your machine.

Good Buy

Bought this battery for my Alienware laptop, to replace one that wasn't holding charge.This battery matches the OEM battery exactly and fit perfectly which was a relief. The battery life is great, like a brand new laptop now. Installation was a pain not due to the battery but Alienware design made me remove many parts to get to the battery. The price was right, I wanted OEM battery but took a risk on this which was half off.In Short: It fit great and functions like new.

Failed after 7 months of use, but 5 star service

UPDATE 4/24/2023 back up to 5 🌟 starsSeller responded within 24hrs and shipped a new battery out to me for free. Recieved 2 days later. Photos show the old battery failed via gas production is the battery pack. Googling what causes battery expansion days it is likely that it was likely due to draining the battery too low, overcharging, or overheating. The more I look into it and the more I re-read the seller's installation & maintenance instructions, the more I think the battery failure is my fault.My Alienware 17 R5 uses a 240watt power supply. The BIOS has battery charging set to the fastest setting. I also run applications that are graphically intensive and pull a lot of watts from the battery which in turn means the battery gets hot.I didn't do the deep discharge and recharge cycling every 3 months as they suggested, so that means the Battery Pack's BMS was likely not calibrated correctly.In the end, I don't know enough to know if the battery failed so early because of my powerhouse of a laptop, my negligence, or manufacturing defects. Therefore, I changed my BIOS settings so the battery doesn't charge at such a high C-rating and I boosted cooling off the laptop with a laptop fan base that the laptop rests on. I did four deep discharge & recharge cycles on the battery as soon as I installed this new battery pack (takes 30 minutes to swap out a battery for my laptop).If this 2nd battery fails before 2yrs of use, you best bet I will be back with a detailed update.INITIAL REVIEW 4/15/2023 2 stars🌟Didn't last. Battery has swollen up and doesn't last more than 20 minutes now. Going to see if seller will help out, otherwise will try a different manufacturer

Battery goes bad after 9 months

The battery started to go bad and expand after nine months. This is probably a repackaged used battery that has very little life left compared to an actual new battery.

Great battery, great price.

Got this battery to replace my original battery on my Alienware 17 R4 laptop. Works great. Unfortunely, This laptop requires a great deal of work just to get to the battery, but once there, installation was a snap. Just plug in the battery cable and place the battery in the laptop case.

Good replacement for Alienware 15 R4

It came well packed, fits perfectly into the laptop. Doesn't overheat during use or charging. Lasts around 3-3 ½ hours. The price is very good in comparison to OEM. The charge is pretty fast. Was easy to replace, if you no how to open laptops. Let's hope it's lifespan will be at least 3 years. It's very functional to have mobility on your laptop.
