1. Only buy quality batteries of known CDR (continuous discharge rate) and correct chemistry from reputable vendors. The CDR represents the number of amps that a battery can deliver continuously without safety issues. As well as creating a ‘green’ usage band, it is relevant in the case that your mod auto fires or the button on a mechanical device is actuated when it is unattended.

2. Be aware of your batteries CDR amp limit and don’t exceed it. Beware, some vendors are known to put exaggerated amp limits on their batteries.

3. NEVER carry unprotected batteries in a bag or pocket. Cases and protectors for 18650s are cheap and easy to obtain.
4. Inspect the wraps of your batteries regularly for damage, repair or replace if they are. The outer shell of a battery is the negative terminal, the wrap is the only thing preventing it from making an electrical connection with your mod or loose change, causing the mod to auto fire or to short circuit leading to thermal runaway and an all-round bad day.

5. Whenever possible charge using a good quality external charger, and don't leave charging batteries unattended especially over night.
6. Replace batteries when they reach 300 cycles or one year of use, which ever comes first. The CDR of a battery will decrease with age, so even if they appear to perform OK replacement is a cheap way to be safe.
7. Always test a new coil build before use to ensure target resistance has been met, and most importantly that’s there is not a short.
8. If you are using a hybrid style 510 connector on an unregulated device, ensure the positive pin on the atomizer protrudes at least 1mm and is not sprung loaded or uses rubber bushes. If the positive pole of the battery comes into contact with both the positive and negative connections of the 510 it will result in a dead short and the battery will vent. The positive connector on your battery will become slightly concave with regular use increasing the chances of this occurring, so do not become complacent.
