Panasonic NCR18650B 3400mAh (Green)

Transcription

1 Panasonic NCR18650B 3400mAh (Green) Official specifications: Real capacity: NCR 3400mAh Size: 18mmx65mm Netweight: 45g <=45mOhm Cut off at 2.75V, full charge 4.35V (Wrong value) This is the latest cells from Panasonic with the highest capacity. The cell used can be discharged down to volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.

2 These batteries are good at both low and higher current.

5 Conclusion This is genuine Panasonic cells and cannot get any other rathing than very good, but remember that they are unprotected!
