Those batteries have a VERY SHARP metal in their tabs! (don't ask me how I know). Thanks for showing the inside to save me from taking one apart. Take care.
Nice trimmer. I had no idea such 18650 trimmers were available. I do agree generic no-brand 18650 cells are awful. They die after some use, but name brand cells like samsung, LG or sony seem to last forever.
That is 18650 battery but the one on there originally seems to be from a weld-type muti-battery pack because it is flat on both ends. It's the wrong type for that charger, it needs type with raised cap on one end (your solder blob did the job to fix that :-) Very common to find these batteries in old laptop battery pack and vacuum cleaner battery pack and most of the time only one battery is gone so most of them can be re-used. They are 3.7V li-ion battery but usually fully charge up to 4.1V or 4.2V.

Hello sir is it safe to charge this battery with 5 volt charger
yes
it is safe as this charger has its built-in battery cut-off circuit and it provides slow charging rate
Amazing :) thanks
I always look forward to new videos from you. You are so good at teaching. Thank you.
Informative video keep sharing❤❤
it is my pleasure

Please also do video inside that usb charger, with circuit diagram.
❤❤❤
why did your usb meter not show the current draw from the battery charger?
I think this charger adapter draws current in milliamps
That is less than the usb meter's sensitivity limits

👍
I was working on a e-bike pack and some of the Chinese made 18650 cells starting spewing purple fluid. I am guessing that is electrolyte?
Bir cep telefonu bataryasını böyle açmıştım ateş alıp yanmıştı😢
Why your charger didnt change to red color when charging that means it didnt charge.
