hi,
just brought a few battery's (18650's Li-ion) for a project brought them from china im pretty sure they are not counterfeit as they seem to be heavy, another one i brought seemed very light i guess that one has a much lower capacity.
I've seen videos on youtube where there's a chunk of metal in a "battery" and a couple of tiny coin cells in the top to make you think it's working when you buy it.
I'm guessing they feel heavy.
jonwhite:
im charging it at 500ma, so if it takes 6 hours to charge can i assume its roughly 3000mah battery?
I could put in a resistor to shunt 495ma of that around the teeny battery I put inside.
jonwhite:
or can it only be worked out on the known current discharge rate?
thanks
Only the discharge counts.
