XTAR 14500 (AA/R6) 3.7V Li-ion 800mAh Protected Battery
The XTAR 14500 is a rechargeable Li-ion 3.7V battery in the 14500 / AA (R6) size format, featuring an integrated protection PCB for safer operation in compatible devices. It is designed for dependable performance where a protected 14500 cell is required.
Why choose a protected 14500 cell?
- Integrated safety PCB – protection against overcharge, over-discharge, overload and short circuit
- Consistent energy delivery – reliable power for compatible electronics
- Standard 14500 format – fits devices designed for 14500 / AA-size Li-ion cells
- Practical charge/discharge limits – designed for controlled charging and stable use
How to use
Use the battery only in devices explicitly compatible with 14500 Li-ion (3.7V). Charge with a compatible Li-ion charger (CC/CV), respecting the recommended charging current.
- Insert with correct polarity and ensure firm contact
- Charge up to 4.2V using a Li-ion charger
- Recommended charge current: up to 0.5A
Safety and compatibility notes
The 14500 format matches AA size dimensions, but the chemistry and voltage are different. This is a 3.7V Li-ion cell and must be used only where 14500 Li-ion is supported.
Important: Do not use as a replacement for standard 1.5V AA alkaline batteries or 1.2V NiMH cells unless the device explicitly supports 14500 Li-ion (3.7V).
