Pragon, замерил стоковый аккум "JS18650 7.77Wh 15A". Результат: 17,9*62

цитата из какого-то забугорного форума, по поводу емкости

There are 2 cells in this - cylindrical 18650 Lithium Polymer or lipo's. Markings on the batteries are "JS18650 7.77Wh". This means that each battery is 2100mAh giving a total of 4200mAh rather than the advertised 4400mAh. Other markings appear to have date of manufacture/serial/batch numbers. There is an intriguing "15A" at the end of the serial number. This may be random or it could be max amps discharge. These appear to be the same cells as used in the iStick 30W.

I ran the batteries empty and then fully charged with SKU 1859500 inline to give me an estimate of actual capacity. Results I received was 4051mAh which is 96% of 4200mAh. This is good enough for me.

Summary:
1st battery/unit:
4400mAh advertising/marketing
4200mAh actual listed on battery
4051mAh on initial charge
3881mAh after 2 months of heavy chain vaping - 4% drop

2nd battery/unit:
4400mAh advertising/marketing
4200mAh actual listed on battery
3997mAh in initial charge

Both batteries have the same manufacturing date of 30th January 2015 so the difference is either measurement errors or degradation of the 2nd battery due to ageing.

перевод думаю не нужен

Лично для себя сделал вывод - пусть работает на стоке, суммарная емкость даже через год будет вполне пригодной для комфортного парения.
