Li-Ion - Lithium Ion Batteries – LI Type Chargers

Shop rechargeable lithium-ion cells, battery packs and chargers from Rocket Distributing. Filter by cell size, voltage, capacity, brand and protection, including Tenergy products. Compare specifications and charging requirements to find the right fit for your equipment.

Protected cells include a protection circuit and can be longer than the nominal cell size. Check the complete dimensions, terminal shape and device requirements.

Unprotected cells need suitable protection in the device or battery pack. A button top does not necessarily mean a cell is protected.

Charging voltage matters. Standard 3.6/3.7V lithium-ion, 3.2V LiFePO₄ and regulated 1.5V rechargeable cells require their specified charging modes. A charger that accepts the cell size is not automatically compatible. For packs, also match series count, connector and polarity.

Follow the battery and charger manuals. Do not charge damaged cells or non-rechargeable batteries. Transport loose cells in a protective case.
