The 600mAh battery is the MT15000 Turbo's secret weapon. In independent testing by Vaping360, the battery actually delivered 602mAh — matching its claimed rating. This is exceptionally rare in the disposable vape market, where most devices overstate capacity by 15-20%. The result: the MT15000's 600mAh battery performs comparably to most 800mAh competitors.

In real-world use, a full charge lasts approximately one day for an average vaper (~350 puffs/day). The battery indicator is informative but has a known quirk: it drains slowly until 20%, then drops rapidly. Some users report getting as few as 12 puffs after the display hits 20%. Plan to charge when the indicator reads 25% to avoid unexpected cutoff.

Charging is the MT15000's weakest point. A full charge takes 78-83 minutes at 0.5 amps via USB-C. Newer devices like the Geek Bar Pulse X 25K charge to 80% in 20 minutes. If you are a heavy vaper who needs quick top-ups, this slow charging speed is a real drawback.
