Battery safety warning (read before use)
Lithium-ion cells can be dangerous if mishandled. Improper charging, shorting, physical damage, or using cells outside their intended design can cause fire, burns, or explosion risk. By purchasing, you agree you understand and accept these risks.
Safety basics
-
Never carry loose cells (use a plastic case—no pockets/purses)
-
Don’t short the contacts (keys/coins = disaster)
-
Do not exceed specs (check your device load + manufacturer ratings)
-
Charge with a quality charger made for Li-ion cells
-
Don’t charge unattended
-
Do not use damaged wraps or dented cells—re-wrap or replace
-
Store cool and dry, ideally around 3.5–3.7V for long-term storage
-
If a cell overheats, hisses, bulges, or vents: isolate it away from anything flammable and move it outdoors if safe to do so.
