LG Battery – What is it in Vaping?

Definition

An LG Battery is a rechargeable lithium-ion power cell manufactured by LG Chem, purpose-built for high-drain devices such as vape mods and pod systems. In vaping, it supplies the continuous current needed to heat low-resistance coils, producing vapour without the voltage sag that causes weak hits or Leaking. Popular models like the LG HG2 (brown wrap) and LG M29 offer a balance of capacity (3000–2900 mAh) and continuous discharge (20 A), giving Australian vapers hours of steady output and a reliable Lung Hit while remaining safe when paired with a clear LED Indicator.

Technical Details

LG batteries use a nickel-manganese-cobalt (NMC) cathode and graphite anode rolled into a cylindrical 18650 or 21700 format. Internal specs: 3.6 V nominal, 4.2 V fully charged, 2.5 V cut-off; energy density ≈ 260 Wh kg⁻¹. A 30 A LG M50LT 21700 delivers 5000 mAh, while the 20 A HG2 18650 gives 3000 mAh. Polymer switch and PTC ring open the circuit at 100 °C to prevent thermal runaway. Continuous discharge rating (CDR) is verified at 25 °C; pulse ratings are higher but should be ignored for vaping safety. Always match battery CDR to your CoilResistance“>coil resistance—Low Resistance builds below 0.2 Ω need 25 A or better. Store at 3.7 V (≈ 40 % charge) to maximise cycle life (300–500 cycles).

Usage & Tips

  • Buy only from authorised Australian vendors; check the LG hologram and batch code to avoid fakes.
  • Keep wraps and top-ring insulators intact—nicks can short against mod walls.
  • Married pairs: buy two identical cells, label them A & B, and always discharge/charge together for dual-battery mods.
  • If the mod’s LED Indicator flashes low, stop vaping; deep-drain below 2.5 V permanently reduces capacity.
  • Never carry loose cells in pockets with keys; use a plastic case to prevent venting.
  • Recharge on an external charger rated for 1 A; higher currents shorten Lithium Battery lifespan.

History & Context

LG Chem began mass-producing high-drain 18650 cells for power tools in 2008; vapers quickly adopted them when sub-ohm vaping emerged circa 2012. The HG2, released in 2014, became the “daily driver” for Australian vapers after Sony VTC shortages, cementing LG as a trusted vape battery brand amid growing safety awareness.
