E-CIG BATTERY SAFETY: NEVER USE A BATTERY WITH TORN INSULATION
Batteries are the most fundamental part of the electronic cigarette. As vapers, we heavily depend on them. Although many regulated mods have protection circuitry built in, we NEVER recommend using the batteries that are Unprotected.
NEVER use a battery that has visible damage.
We have shown four types of insulation damage in the picture: no insulation at all, no insulation of the positive pole or the negative pole, and damaged insulation of the positive pole. These battery shouldn't be used anymore as it might short and explode.
