Lithium battery charger is an electronic device designed to safely recharge rechargeable lithium-ion and lithium iron phosphate (LiFePO4) cells. A multi-size lithium charger is built with adjustable slots and smart charging circuits, allowing it to charge different cylindrical battery types such as:
26650 – Large-capacity lithium cells, often for flashlights & power tools.
18650 – Standard lithium cells, common in laptops, power banks, and e-bikes.
16340 (RCR123A) – Compact lithium cells used in cameras, torches, and medical gear.
AA / AAA – Can be rechargeable lithium-ion (1.5V type) or Ni-MH/Ni-Cd types, depending on charger support.
