these batteries really keep load. i am very happy with themviolet, 3500ma, 18650

Good high capacity batteries working well in my vape. Value for money and quick shipping is a plus.

hi I bought 4 of these batteries but one of them did not work and after a week the second one did not work.

These four Samsung 35E 18650 flat-top rechargeable Li-ion batteries do exactly what I wanted.They are exactly 18mm diameter and 65mm long, unlike some 18650 button-tops which do not fit because they are 19mm diameter and 67mm long!The instructions enclosed are clear and unambiguous, read them!Use common sense and BE CAREFUL when charging them, using them and storing them. The little case they come in is handy for storage without risk of shorts and consequent explosive fires.Each of the four cells tested out between 3390mAh and 3410mAh on three charge-discharge cycles taking absolute ages in my four-cell Smart charger, and they all improved slightly on the subsequent cycles, but I doubt they’ll approach 3500mAh.Two now live in a couple of satisfactorily noisy solar-charged fox-repellers where the original “1800mAh” cell in each had died after a couple of winters and not enough UK sunshine.

Really good value, good life in the batteryWill buy again . Fits perfectly in my vape

Very happy with them

Good batteries last reasonably well. Only thing is it needs to have plus and minor signs on them as a person who doesn't know might put them in the wrong way round. But other than that very good

Extremely quick shipping
