Why is my battery no longer holding its charge?
Just like us after a long night out, batteries get tired with age. If your battery life is melting away like snow in the sun, your cell has likely reached its maximum charge cycle limit or you're vaping at a wattage too high for its capacity. Treat your battery with respect, not like a 1995 TV remote battery.
Technically, mAh capacitynaturally decreases after 300 to 500 charge/discharge cycles. Avoid fully draining your batteries and use an external charger rather than the USB port on your mod to extend their lifespan. If your battery gets unusually hot, don't wait for an explosion: replace it immediately.
