Vaping Battery Safety Part 2 - Temperature is the Enemy

The other way a battery ages from high temperatures is loss of “capacity”. Capacity is a measure of how long the battery will last when you use it. For vaping you’ll usually see it expressed as the number of “mAh”, milkiampere-hours, it is rated at. If a battery gets too hot and is damaged, its capacity starts to drop. Have you ever had to replace a battery after only a few months because it wasn’t lasting nearly as long before needing charging? It could have been due to overheating of the battery, speeding up its aging and loss of capacity.
