⚠️ 14500 Charger Safety Guidelines
- Always Use a Li-ion Specific Charger: 14500 cells are 3.7V Li-ion. Never use an AA NiMH charger—this may cause overcharging, cell damage, or safety hazards.
- Distinguish Battery Chemistry: 3.7V Li-ion (full charge 4.2V) and 3.2V LiFePO₄ (full charge 3.65V) require different modes—do not mix.
- Select Appropriate Charge Current: 14500 cells charge best at 0.3A–0.5A. If manual setting is available, select an appropriate current.
- Avoid High-Temperature Charging: Keep away from heat sources and direct sunlight; ensure good ventilation during charging.
- Remove After Full Charge: Although chargers feature auto-termination, prolonged connection to power may still affect battery longevity. Remove batteries promptly after charging.
