Rechargeable Lithium Batteries

Rechargeable lithium batteries provide high energy density, stable voltage output, and long cycle life, making them ideal for demanding applications where reliability and performance are critical. This category includes the most widely used cylindrical formats — AA, AAA, 14500, 18650, 21700, and 26650 — suitable for professional, industrial, and consumer devices.

Unlike traditional NiMH or alkaline cells, lithium-based rechargeables maintain consistent power delivery throughout the discharge cycle and exhibit minimal self-discharge during storage. Depending on the specific chemistry, they offer enhanced safety features, higher discharge rates, and improved capacity retention over hundreds of charge cycles.
