Efest batteries are not to be trusted on their labeling.
I would suggest you restrict your battery use to well known and tested batteries like the LG18650HE2/4, Samsung 18650-25R and the newer LG18650HG2 and Samsung 18650-30Q models.
Even though some Efest batteries are actually good re-wraps, like the 2500Mah 35A version, which is actually an LG18650HE2(20A). They endanger vapers by placing exaggerated specifications on their products.
