M5Y1K battery is a must-have accessory for your computer, ensuring that you are never out of power no matter where you are. Whether you are on the go, taking a camping trip, attending a business meeting, or just need to work from a remote location, it is the perfect companion for your computer
How to purchase the correct replacement battery?
To purchase the correct replacement battery for your laptop, follow these steps:
1. Check your specific laptop model name by pressing [Win] + [R] key and entering [msinfo32] or [dxdiag]. Click OK to find your system model. Use your laptop model name to find the correct replacement battery.
2. Check your original battery's type model and shape by removing the laptop back cover. Use this information to search for the replacement battery.
Note: Dell laptops have a wide range of batteries for each series, so when purchasing a battery, please base your decision on the specific model number of your laptop, such as "Dell Inspiron 15 3567," rather than just the series. Searching and buying through "Dell Inspiron" alone will almost certainly result in purchasing the wrong battery. Alternatively, you can remove your original battery and buy a replacement based on its model number.

I am very pleased with my Dell laptop internal battery order. Exactly what I ordered and was compatible with my laptop. Already installed and working well. Came on time.

Buying a replacement battery directly from the brand manufacturer would've cost $130 + taken more than a month for delivery. I didn't have a month when my battery was depleted thus affecting my laptop performance. I even talked to someone about faster delivery, wanting to see if there were any options for that and was told "WE CANNOT CHANGE DELIVERY TIMES", like that in all capital letters. Also I really wasn't wanting to pay that large of a sum for a battery, for that cost I might as well put that kind of money into buying a new laptop. Anyway, this works out great. Its compatible with my laptop, is the same voltage as my old battery, and is doing what it needs to do. The battery does not come fully 100% charged, but it charges up fully within a half and I get several hours of a charge without the adapter needing to be plugged in. Why bother wasting your money with the manufacturer when this works just the same? I will recommend this to anyone needing a new battery!

Thank you for this battery for my Dell laptop! The one that came with the laptop stopped holding a charge, so when I found this one, I took a chance and ordered it and it works great. I was so happy it was compatible with my laptop. It installed easily - slides right into the spot meant for it in my laptop and locks in place fine. Very speedy shipping too. Good value for the money.

Bought this to replace original power block that came with the laptop. Plugs in snugly to the laptop. Was recognized by the laptop and charged to full. No fuss.

I purchased this battery and with death in family I just got around to installing this. After opening the back of my computer, I realize this is not even close to the size of battery that will fit in my Dell Inspiron 3583 laptop. My battery is square, and this battery is long and rectangle shaped. I am out of the return window by 2 weeks. I immediately started a chat with an Amazon associate who said they would refund my money, but it's been a week now and no refund was issued. Apparently I'm screwed out of $30. Be warned, it does not fit Dell Inspiron 3000 series laptop, which it clearly says it does in the description.

The battery arrived on time and was simple to install. I've had this battery installed on the laptop for 3 months now and has worked flawlessly and got me through a couple of power outages. I would recommend this battery when a replacement is needed.
