Worked great in the Dell laptop.

Fits my hp laptop. Can't bear the price!! Best BUY doesn't Cary batteries. This one cost $140.00 @ batteries plus. Go figure.

I have an 8-year-old Dell Inspiron 3521. It stays plugged in 95% of the time while using it, but in the rare occasion that I needed to use it on battery it would only last about 15 minutes, so I decided to buy a new battery. Swapping the battery out is extremely easy. Have not tested the full battery life, but it appears to be performing just as good as the stock battery did when it was new.

Buying an off-brand battery can be a little bit of a gamble sometimes. You can get cheap replacement cells, or you can get newer genuine cells. I relied a bit on some of the reviews to determine this, so I wanted to provide my own review in order to add some additional information for other purchasers. I have included pictures of the new Bytec 9 Cell next to a genuine Lenovo 9 cell as well as some screenshots of the new and old battery stats from the Lenovo power management software. A lot of other batteries / reviews didn't provide this kind of info, so I wanted to increase people's confidence in buying this battery.Off the bat, you can see the battery is identical in shape and size. I have read sometimes that these do not fit securely in the laptops (play in the locking mechanism). I was very happy to see that this was not the case for this battery, and it clipped securely into place. I've included some images of the two batteries next to each other if you want to compare labels or details.Now to the important part, performance. My old, genuine battery (purchased new with my W520 in 2011) was dying. Like, within 40 minutes the laptop was completely dead. Looking at the Lenovo power management tool, it was showing somewhere around 45Wh of capacity left (which is less than 50% of the original capacity). This new Bytec battery is listed as a 94Wh version (should be a direct replacement), but as seen in the screenshots I am only getting 86.5Wh (which is a 10% reduction). This is why I am docking it down to 4 stars. If the battery is normally able to provide 300 minutes of run time, that's 30 minutes I am missing out on (roughly, not actually).Another thing to note: These are listed as SANYO cells by the Lenovo power management tool. It states the battery was manufactured in June of 2020, with the original use date being in 2013. I believe another user claimed they saw a weird original use date without any issues, but I haven't noticed anything odd.Only time will tell how this holds up over years. I've set a reminder in my phone to update after one year to see how it has held up. I have heard stories of these batteries being good in the beginning and then slowly tapering off.

Very simple process. Ordered the battery arrived on time, removed the old battery slid the new one in. Instructions said to charge to 100% then run the battery out and recharge, which we did. Charges rapidly, works great. Good value for the money, fits perfectly, very happy with this product

Our laptop's battery on the MacBook Pro was expanding to the point it was making our laptop bowl. It looked like the keyboard was popping and the laptop wouldn't close all the way anymore. Looked into getting it fixed by Apple and they were going to charge $200 plus dollars for the repair and the guy said that if anything goes wrong they are not responsible and we will still have to pay for the service regardless if they are able to do it or not. I thought that was really unfair of them and very bad customer service on Apple's part. So I went to Youtube watching videos on the process and it didn't seem that hard so I purchased this battery for a 2015 MacBook Pro for around $60 after tax and shipping. The process went fairly smooth as I already had the tools to open up the laptop. I am fairly decent at repairing electronics as I been doing it for a few years as a hobby. I also have some soldering skills just to give you an idea of my skillset. However, this installation was fairly easy. The hardest part about this battery replacement process was removing the actual old battery as it has adhesive and is stuck to the laptop casing. All I can say is that if you are patient, you will have no problems. Just take your time and carefully pull away the battery slowly as to not puncture it. There are gases in it that is not good to inhale. Try to do it in a well ventilated area. I also used a dull butter knife to assist with scraping the battery adhesive away from the casing. Just go VERY slow. Take your time and do not rush it. Watch at least 2 or 3 Youtube videos to get a good idea of what you are up against before starting and also buy a good tool kit for the job. You can find one on Amazon. Just search MacBook Pro repair tools or something to that nature.After the battery was installed, it now looks back to normal aesthetically and the life of the battery lasts longer than the old one. Anyway, thanks for reading and hope this review helps you out.

Right most latch tab broke off the second it was inserted, and the slider switch popped out. Now it's extremely loose in the machine. Absolutely horrible quality control and poorly constructed product. I was able to reinstall the switch, but the broken latch tab is a lost cause. If it was the middle latch, it would have been fine. Even the left tab might have been okay.Oh, and yes, the designed Watt Hours is wrong. But I knew that going into it. I should note to anyone who purchases, you will get 96Wh out of it, but the chip on it or reporting says only 84.24, yet after a few discharge cycles, it will go up to ~96 at full. At idle I get about 11 hours of battery life.

Buen rendimiento de batería hasta ahora
