I was recently gifted a Warsun SQ03 Plus which came with a 3000mAh 18650 battery.
I decided to test it to see how it compared to a Samsung 30Q 3000mAh 18650 Battery.
My tester only discharges to 3.0v so a full 3000mAh isn’t possible.
That being said, you can see the Warsun battery doesn’t come close to 3000mAh.
Warsun 3000mAh:
My approximately 2 year old Samsung 30Q(3000mAh):
After testing it, I thought I’d peel the wrapper off and see if there was any writing on the Blue wrapper underneath.
Unfortunately there wasn’t any writing on the blue wrapper.
So I decided to peel off the blue wrapper to see if anything was written directly onto the cell:
Unfortunately nothing was printed on the cell either.
It’s kinda hard to see in the pictures but the cell actually has 4 dents in it.
I was planning to rewrap this cell but after seeing the dents, I’m going to discharge and recycle it…
