New lithium-ion batteries achieve maximum capacity after a single discharge and charge cycle. For optimal performance, complete one full cycle before regular use.
After field use, place the battery in the compatible BC-30D charger until fully charged (indicated by green light). Charging time varies based on battery capacity and ambient temperature.
For maximum battery lifespan, charge at ambient temperatures between +10°C to +20°C. The permitted charging range is 0°C to +35°C. High-temperature charging can cause irreversible capacity loss.
