I have 4 18350 Vapecell batteries that I purchased from a reputable vendor. (Recommended by Mooch's posts and countless members on ECF.) Purchased at the beginning of October- each has about 10 recharge cycles. I use an Opus BT-C3100 charger. I used the charger to test the internal resistance, which came out at 82, 103, 116 and 86. Those numbers seem very high. (I also tested my 18650's, that are about a year old, and have countless charge cycles- on same charger) They all range 40-50 as far as internal resistance. Thoughts? Are the 18350's legit? Are they safe to use?
