Galaxy S21 Ultra Battery, (Upgraded) MAXBEAR 5500mAh 3.85V Li-Polymer Replacement Battery EB-BG998ABY for Samsung Galaxy S21 Ultra 5G SM-G998B/DS SM-G998U with Repair Tool Kit

got the battery replaced and phone and battery are charged.

No problem. It's very slow, so it's better for this battery to charge quickly with my old, weak one.

This isn't my first effort opening electronics to replace components such as batteries. Samsung wanted a lot to replace my battery so I thought I would give it a try. There are a number of kits available and I chose this one because it was the quickest to arrive. Looking back it was a mistake. Let's go through the kit: Pick: Worked Screwdriver: Worked but magnetic would have been a great help. Ended up using my own which was magnetic. Suction cup: Worthless, worthless, worthless. Having a functioning suction cup is critical to the process. Metal tool: Why you would include a metal tool rather than plastic is beyond me, an oversight on my part. Sim removal tool: Because? Two sticky strips: Wasn't sure about these so I stuck them to the bottom of the battery. Battery: The connector cable from the battery was too long and went past the socket on board. I had to bend it back a bit to make it fit. Fingers crossed this doesn't cause any problems. With so many options available I would avoid this one.

Honestly really easy to install and watch YouTube video and you have everything you need..if you have a heat gun or pad warmers it makes the face screen come off real quick

Kit good. Instructions not so much.

Item works for a battery replacement, just know that the claimed mAH is total bogus. It says 5500 in the pic, and when it arrives it says 5800 on it. Then in real world testing it has just over 3000. So don't be expecting any good battery life out of it, but it will keep an otherwise scrapped phone going

Exactly as shown

Perfect fit. Works as described. Tool kit made installation easier.
