850mAh Battery – What is it in Vaping?

Definition

An 850mAh battery is a compact lithium-ion power source rated to deliver 850 milliampere-hours of current before needing a recharge. In vaping, it sits between ultra-portable 300–650 mAh pen cells and larger 18650/21700 removable batteries, giving Aussie vapers a sweet spot of pocket-friendly size plus a full day of moderate mouth-to-lung (MTL) vaping. The sealed unit is found in entry-level pod kits and slim AIOs, providing consistent 3.2–4.2 V output to heat Nicotine“>0mg nicotine or nic-salt e-liquid without the bulk of external cells or complex menus.

Technical Details

Internally, the 850mAh battery uses a single 18350-sized lithium-cobalt or lithium-manganese cell with a nominal 3.7 V and maximum 4.2 V when fully charged. Continuous discharge rating is typically 8–10 A, enough for 8–15 W MTL coils but unsuitable for sub-ohmcloud chasing. Recharge is handled through an onboard micro-USB or USB-C board limited to 0.7–1 A, taking 60–90 min from flat to full. Pass-through vaping is usually supported once the cell reaches 20 % capacity. Variations include auto-draw (no fire button) and manual models, both sharing the universal Thread“>510 thread or proprietary pod-specific connections. Protection chips guard against over-charge, over-discharge, short-circuit and overheating, making the 850mAh battery one of the safest formats for beginners.

Usage & Tips

  • Prime new pods, then take 3–5 gentle puffs to let the wick saturate before chain-vaping; this prevents dry hits that stress the small cell.
  • Recharge when the LED flashes or output drops—deep drains shorten lithium life. Unplug once full; overnight trickle can degrade capacity.
  • Keep contacts clean and free of e-liquid; leaking nic-salt can corrode the 510 thread and autofire the device.
  • Store below 40 °C (no glove-box in summer) and at 60 % charge if you won’t vape for a week, prolonging cycle life past 300 charges.
  • If the battery swells, hisses or refuses to hold charge, recycle it at a local B-Cycle drop point—never bin lithium cells.

History & Context

When Australia’s nicotine prescription laws pushed vapers toward low-wattage, 0mg nicotine pod systems around 2020, manufacturers swapped bulky 18650 mods for slim 850mAh sticks that still satisfied MTL cravings. The capacity quickly became the “goldilocks” standard for pocket kits, offering double the life of early 350mAh Juul clones without doubling the size.
