Battery Safety & Handling Guidance

Visual Inspection Before Use

Do not use if the outer wrap is torn or scratched.
Do not use if the top insulator ring is missing or cracked.
Do not use if the metal casing shows dents.

If wrap damage is detected, stop using immediately and re-wrap or dispose responsibly.

Transport & Short-Circuit Prevention

Store spare batteries in protective cases.
Never carry loose batteries with keys or coins.
Avoid direct terminal contact with metal objects.

Thermal Behaviour & Charging

If the battery becomes warm after extended use, allow it to return to ambient temperature before charging.

Charging elevated-temperature cells may accelerate internal wear.

For optimal long-term consistency, use a quality external charger when possible.
