• ⭐ Industrial Craftsmanship & Warranty — Manufactured under strict aging test procedure, OEM private label and bulk customization available, 12-month full quality warranty

• ⚠ 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 (potassium hydroxide alkaline solution); 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. Although this battery has built-in short-circuit protection, continuous shorting of any contact will still cause overheating. 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-CD compatible charger (constant current with negative delta-V cutoff or timer-controlled cutoff). Do NOT use a Li-ion CC/CV charger on this Ni-CD battery — the voltage profiles and cutoff logic are different, and using the wrong charger can cause overcharge, overheating and reduced cycle life.

• ⚠ This Ni-CD battery contains regulated cadmium — 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.
