Fully charge overnight unplug while in use
The replacement battery works just great for most laptops it's the battery that is at the root of most slow or dead units what does that mean if you can only turn on your laptop with the power cord plugged in yes your battery has moved on to lithium heaven and your laptop will start blinking out but fear not it's not dying it's protecting itself and telling you to replace the battery. Most laptops have a 3 to 5 year battery operational life of course based on use once you replace it fully charge it overnight DO NOT plug it back in during normal use unless battery level is low continue to change it overnight when not in use and your battery should give you years of reliable service

Brought my laptop back to life
I am so glad I was able to find this battery! After having my dell laptop since 2017, the battery did not work anymore. I had to keep my laptop plugged like a PC to be able to use it. Now that I replaced the battery my laptop is good as new, and I can actually take it with me when I travel.

long lasting battery
I am not any kind of techie, so I really only care about how long the battery lasts, prompt secure delivery, and costs. On these points this battery and supplier were great. The price I thought was very reasonable compared to all the options including at Amazon and brick and mortar. The product came very quickly delivered in a very secure and non-damaged box. Finally, the battery life was great I had this battery for almost three years and used my computer a lot before it finally gave up. Overall, I am very impressed with the supplier and the product.

Replacement battery for an old Dell laptop, died 7 months later.
My Dell is over 8 years old but it's still kicking. The original battery only last about a good hour use before it the laptop will power off. Since the laptop is at its end of service/life. You can no longer buy the batteries from Dell. Took a gamble on this replacement and to my surprise. The cell are made in Korea and assembled in China. My guess these cells are probably made by Samsung. Everything fits, snaps right in and was about to use the laptop for about an hour before I decided to plug it in and charge it up (went from 68% down to 62% in 30 minutes so that's really good) So far so good and no error whatever after leave the laptop on and unplugged. Will update again at a later date to see if the cell and it's life cycles holds up. Update - 04/04/2025 Well the battery just died one day and computer failed to turn on. Got the loud error beeps, end up removing the battery and stick the OE one back in just to back up my data again. The laptop was plugged in 90% of the time so I'm not sure what went wrong. I originally gave it a 5 star and now changing to to 1 due to such a short life span and the laptop being plugged in majority of the time while in use.
