How many charge cycles can a battery withstand?
A quality battery typically supports between 300 and 500 full charge cycles before showing visible signs of fatigue. One cycle corresponds to a full discharge and recharge, meaning that with daily use, your battery will stay in peak shape for about a year to a year and a half. Beyond that, autonomy decreases and the voltage drops more quickly, turning your faithful companion into a tired straggler.
To keep the fun going, avoid letting your batteries drop below 10% charge and prioritize a dedicated external charger over your mod's USB port. A slow, steady recharge preserves the internal chemistry better than a sudden, emergency boost. In short, as soon as your battery struggles to last the day or heats up abnormally, it is time to give it a well-deserved retirement in the recycling bin. A fresh battery is the guarantee of a consistent and safe vape.
