MAXBEAR Galaxy Note 20 Ultra Battery, (Upgraded) 5000mAh 3.85V Li-Polymer Replacement Battery for Samsung Galaxy Note 20 Ultra 5G SM-N986 N985 N986U with Repair Tool Kit

The battery was a little big and the plug for it was kinda funky but it did work perfect and has helped my phone keep a better battery. Was easy with watching a YouTube video.

I bought this and installed it wow it's working perfect only things is that it's slightly bigger than the original in width but with a firm press it goes into place. I am pleased with this product

I received this battery in the mail today. I opened the instructions (written in broken English) and removed the battery out of its wrapper. I used a pair of small scissors to gently cut the plastic off. When my scissors made contact with the metal, the battery BURST INTO FLAMES. I. Kid. You. Not. I dropped the battery on the floor, which put out the fire, but then I got a whiff of the ungodly FUMES coming from the battery that almost knocked me off my chair. I immediately threw the entire battery back in the cardboard box and rushed it outside. It has been several hours, and I can still smell the fumes in the house. I have no idea what happened here, and honestly it doesn't matter, because there is nothing I could have done to cause THAT to happen. I have no doubt, had I installed this battery into my $1200 phone, it would have destroyed it. (as another reviewer wrote). I have asked for a full refund, however it isn't possible for me to return the battery (or even touch it) due to the above reasons. One other thing to note: this is NOT an "official" Samsung cell phone replacement battery, nor does it appear to be any kind of "standard" battery we would buy in the US. This item is clearly EXTREMELY unsafe and shouldn't be sold.Update: I received a message from the vendor that they would refund my money when I return the item. As I mentioned above, I cannot return this item (or even touch it.....the battery had a burn hole through it). I believe it is illegal to send such a dangerous item through the mail.Sounds like I will be stuck eating this one. At least I didn't attempt to put the battery into my $1200 phone. Lesson learned.

Same battery time as with 3 year old battery.

The kit worked well for opening the case and following a Youtube to replace the battery. Was only missing something to pry the battery up. (I was hesitant to use a screwdriver so I didn't scratch or bend something, but I found something suitable. Everything else went smoothly, including using the provided adhesive strips to reseal the case. (Cut it into narrower strips with scissors.)

Not sure how Maxbear is getting away with claiming this battery is over 5000 mah. Installed correctly using the provided tools. Noticed phone was quite hot after booting up. That dissipated after a few cycles. The estimated capcity has risen some but is obviously a far cry from the claimed capacity. Too much trouble now to remove it for a return. Nice one!

Package came packed with tools and ready for install! If you are handy with tech then I recommend this brand as it says exactly what it comes with and has all the tools for install. It worked the first time I installed but the phone failed so I removed the battery for use with another phone later.

I was a bit nervous at first changing out the battery of a $1400.00 phone, but it worked out perfectly and the kit comes with everything needed to change out the batteries.
