LG Chem is one of the world's largest battery manufacturers, producing more than 40 million cells per year. LG Chem produces both lithium-ion and lithium-ion polymer rechargeable batteries.
The 18650 battery is a lithium-ion cell classified by its 18mm x 65mm size, which is slightly larger than a AA battery. They’re often used in flashlights, laptops, and high-drain devices due to their superior capacity and discharge rates. 18650s come in both flat and button top styles, and usually boast 300-500 charge cycles.
