Lithium rechargeable battery XTAR 14500 3.7V 800mAh

Rechargeable XTAR 14500 3.7V 800mAh is a compact lithium-ion cell offering a nominal voltage of 3.7V and a rated capacity of 800mAh. The cell is intended as a slim, rechargeable alternative to alkaline AA-sized batteries in devices that accept 14500-format cells. It provides a stable voltage output over discharge and supports repeated recharge cycles for continued use in portable illumination and small electronics.

Advantages

The XTAR 14500 battery delivers consistent 3.7V output and useful energy density in a compact form factor. Its rechargeable chemistry reduces the need for single-use cells and lowers operating cost over time when used with a compatible charger. The cell's moderate 800mAh capacity balances run time and size, making it suitable for devices where space is limited. Designed for reliable voltage under typical loads, it is appropriate for applications such as LED flashlights and small electronic devices that require a 14500 cell.

Suitable for

• LED flashlights and headlamps that accept 14500 cells
• Portable electronics and small gadgets with 14500 battery compartments
• Battery replacement in devices originally designed for slim lithium cells
• Low- to moderate-drain devices where compact rechargeable cells are needed

Key specifications

• Cell type: lithium-ion rechargeable
• Nominal voltage: 3.7 V
• Rated capacity: 800 mAh
• Form factor: 14500 (AA-sized length with Li-ion voltage)
• Typical use: low to moderate discharge rates
• Rechargeable: yes, requires compatible charger

How to use

Install the XTAR 14500 cell in devices that explicitly support 14500-format lithium-ion batteries and observe correct polarity. Charge the battery only with a charger designed for lithium-ion cells and follow the charger's instructions for charging current and termination. Do not use a charger intended solely for NiMH or alkaline cells. Monitor the cell temperature during charging and discharging; stop use if the battery becomes unusually hot, deformed, or damaged.

Usage recommendations

Store and transport the cell in a non-conductive container, avoid short-circuiting the terminals, and keep the battery away from high temperatures and direct sunlight. For prolonged storage, maintain a partial state of charge (around 40–60%) and check periodically. Replace the cell if capacity noticeably decreases or if physical damage occurs. Use only chargers and devices that are compatible with 3.7V lithium-ion 14500 cells.
