The Sony US18650VTC4 batteries feature a 30A self-discharge rate and long cycle life. The solid charge and discharge capability reached by IEC standard batteries is unprotected cell types. We strongly suggest using unprotected batteries in protective devices or by experienced users. The VTC4 batteries have a safer Li-Ion chemistry, which requires a protection circuit and has a low risk of venting with flame or explosion.
The authentic Sony VTC4 batteries match the green color shrink. For fake Sony batteries, the QR code is printed in a tightly fixed place and does not change the position relative to other markings on the batteries from cell to cell. The QR code does not have a rigidly fixed position for authentic Sony vape batteries. The place of its application can "walk" relative to the rest of the inscriptions on the batteries. Moreover, authentic batteries employ a board so that they do not fail, which, during charging, protects the internal microcircuit from short circuits and recharges it. In prolonged non-use, the batteries will not allow them to be re-discharged.
* The Sony VTC4 authentic batteries are unprotected cells intended for use in protected power packs only, NOT individually or as a standalone product. To operate safely, Sony VTC4 authentic batteries must have extra protection with PCB [protection circuit board] or BMS [batteries management system], which is not included.
