I bought some new cells in from malaysia in packs of 10 see the first pic
98oo mah supposedly with a pcb protection. They weighed 25 grams
Had a small pack sagging so I looked for a bad cell and found one . Charged and discharged a couple of times through a half amp torch bulb. 3.9V start to 2.6V end
Current .426 amps
That took 16 min 42 seconds
Average voltage 3.25
3.25 x .426 watts=1.3845 watts
1.3845 watts x 1000 seconds =1.3845 x 1000/3600 whrs= .0384583 WH is that how it goes?
Not very good anyway so I pulled it apart to have a look at its insides
Didn't find a pcb anywhere?
