• ⚠ Do not disassemble, puncture or modify the battery housing — cell damage may cause electrolyte leakage or overheating. The electrolyte inside Ni-CD cells is corrosive; avoid any contact with skin or eyes.

• ⚠ 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 or direct sunlight for extended periods.

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

• ⚠ This battery contains cadmium, a regulated substance. 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.
