Does not seem like a difficult task, but I want to do it right. I saw/read two conflicting methods.
I have a 26650 BT that is very feeble and lop sided! It only makes a connection with One out of Five of my primary chargers.I can deal with the lopsidedness but NOT the lack of contact.The most important charger would be my Opus BT-C3100 2.2 which can charge @2Amps and do capacity tests which I enjoy. It does not work in that. It also does not work in my Fenix ARE-C2 chargers either. The only one it works in is my K’Power L2!
Method #1 was a thread from 2012 on ECF. His pictures were gone but that did not matter. It was a simple job because the the BT is connected by Spot welds. The MOST important thing he said was DO NOT use any metal objects to remove the BT.Can be dangerous and could short something. He also said when removing the wrapper to go 5mm or so down from the Positive pole. That made sense. He did not want to short anything out. After he carefully removed the label and terminal insulators he said you could just pull the BT. off. Not sure what Non metal tools he had if that did not work.
Method #2 was a video a few years old in the Turkish language. But I could see it, that was all that mattered.
It was a Protected Ultrafire 18650. This guy was CRUDE!. Not only did he use metal tools[screwdriver, needle nose and mini snips to cut the wrapper] but he saved the wrapper! He first used mini snippers to cut 3 or 4 small incisions at the very top of the wrapper[positive pole]. He then peeled it back and removed the BT w/ his metal tools. Also removed the protection circuit.Then he pressed down the cut wrapper as well as he could and placed the battery in his Vape mod!! That is not safe. The metal can will eventually be exposed and it may blow up!
The first guys method seemed the safest and most logical.
Here are a few questions. My buddy put solder blobs on several of my FT’s. I used a small file to flatten them out a bit. I am still here!
1. Was that a safe thing to do?
2. What is the easiest and safest way to Remove BT’s from Unprotected batteries?
3. What is a safe tool to use If I can not just pull the BT off?
Thanks.
P.S. I purchased a Folomov A4[On sale $25] BEFORE I got the battery in question. It is due to arrive Friday or Saturday. Even If I get a connection in that charger I still want to remove the BT so I can use it in my opus.
