Lithium Battery – What is it in Vaping?

Definition

A lithium battery is the rechargeable power source that fuels every VapeMod“>vape mod and pod kit. Inside its sealed metal casing, lithium-ion cells store electrical energy and release it on demand to heat the coil, turning e-liquid into vapour. Lightweight yet energy-dense, these batteries provide the sustained wattage needed for anything from a discreet mouth-to-lung draw to a massive Hit“>lung hit, making them the beating heart of modern vaping.

Technical Details

Lithium batteries rely on lithium-ion chemistry: lithium ions shuttle between a graphite anode and a metal-oxide cathode through an electrolyte, creating a flow of electrons that powers the device. Key specs Australian vapers will see are milliamp-hours (mAh) for capacity (e.g., 3000 mAh) and continuous discharge rating (CDR) measured in amperes (A). Common formats include 18650 (18 mm × 65 mm), 20700, and 21700 cells, plus built-in lithium-polymer (Li-Po) packs in smaller pod systems. Nominal voltage is 3.6–3.7 V per cell, delivering 4.2 V when fully charged and dropping to around 3.2 V before the LED indicator signals “low battery.” Low-resistance builds draw higher current, so matching battery CDR to Resistance“>coil resistance is critical for safe operation.

Usage & Tips

  • Charge smart: Use an external charger for removable cells; avoid overnight charging to reduce leaking electrolyte risk.
  • Check wraps: Torn battery wraps can short against the mod’s metal body—rewrap or replace immediately.
  • Match your build: Ensure the battery’s CDR exceeds the amp draw of low-resistance coils; use an Ohm’s Law calculator if unsure.
  • Storage: Keep spare cells in a plastic case, away coins or keys, and store at 40–60 % charge for longevity.
  • Recycle responsibly: Drop spent batteries at local e-waste or vape shops participating in the Batteryback program.

History & Context

Lithium batteries entered vaping around 2008, replacing earlier Ni-MH packs and enabling variable-wattage mods. Their high energy density and rechargeability fuelled the shift from cig-a-likes to sub-ohm cloud machines, shaping today’s diverse liquid ratios and coil technologies across Australia’s vape market.
