Storage conditions: Store batteries in a cool, dry place to prevent heat damage. Ideal temperatures are between 15°C and 25°C (59°F and 77°F). High temperatures can degrade battery cells. Additionally, for long-term storage, keep batteries partially charged at about 50%, as this prevents deep discharge.

Regular maintenance: Inspect contacts and terminals for corrosion or dirt. Clean these areas with a soft cloth to ensure good electrical conductivity. Periodically test battery performance using a multimeter to monitor voltage levels. Batteries showing rapid voltage drops indicate a need for replacement.

Correct usage: Avoid continuous high-drain operation as it can cause overheating. Limit transmissions and use lower power settings whenever possible. Operating at 5W instead of maximum power (max 5W) can help extend battery life. Furthermore, allow batteries to cool between uses to avoid overheating.

By implementing these practices, users can significantly prolong the operational lifespan of FT-817 batteries.
