Many thanks Izan.
I am not understanding why the battery should be irreplaceable. You desolder it, put in a new one and solder the new one.
Do you have any idea who is selling this battery? With corona and everything, I must do this myself.
If it is soldered in place, it is generally considered permanently installed and/or non serviceable.
Obviously, if you have the time, skills and equipment, almost everything is serviceable.
You may find that that battery is available, but if you are not buying dozens of dozens, the unit cost is probably very high when factoring in the cost to transport hazardous materials.
I presume it to be Lipo based on the form factor and voltage rating.
In my experience, a li-ion battery of that size would consist of only (1 or 2) 3.7V cells. I am not positive it is Li-po, but fairly confidant.
Anecdotally; about a year ago, an ECF user wanted to replace the 380mAh Li-ion batteries in his "cig-a-like" units.
Having found the batteries in China, the user discovered that the price for the individual direct replacement cells plus shipping and importation fees, exceeded the cost of the original cig-a-like product by two or three times.
I understand your desire to keep using what you love and applaud your willingness to "get your hands dirty", but often what should be simple and cheap is neither.
Cheers
