Protected 14500 cells come with an integrated protection circuit that safeguards the battery against overcharging, short-circuiting, and other potential hazards. This added protection makes protected 14500 cells slightly longer than unprotected ones. While this safety feature enhances the battery's lifespan and performance, the extra length may cause fitment issues in devices with limited space for batteries. Always check if your device can accommodate the slightly larger size of protected cells.
