• ⚠ Do not disassemble, puncture or modify the battery housing — cell damage may cause electrolyte leakage or overheating. The electrolyte inside Ni-MH cells is corrosive (alkaline KOH); avoid any contact with skin or eyes. In case of contact, flush immediately with plenty of clean water and seek medical advice.

• ⚠ Keep battery terminals away from metal objects such as coins, keys and jewelry to prevent accidental short-circuit. Do not expose the battery to high temperature above 60 degrees C, direct sunlight or open flame for extended periods.

• ⚠ Only charge with a Ni-MH compatible charger (constant current with negative delta-V cutoff or timer-controlled cutoff). Do not use a Li-ion CC/CV charger or a mismatched charger, and avoid leaving the battery on charge continuously for more than the recommended charging time.

• ⚠ This Ni-MH battery is cadmium-free but still contains regulated metals. Do not dispose of it with household waste. Return the spent battery to an authorized electronics or battery recycling collection point in compliance with local regulations.
