Battery safety isn't a one-time check. It's a mindset that you reset with every new product, every new batch, and every new supplier. After you've verified a batch, don't forget the basics of handling:

• Store batteries in a cool, dry place, away from direct sunlight and flammable materials.
• Use proper storage containers—ideally fireproof bags or metal cases for loose cells.
• Ship batteries as hazardous materials (Class 9), with proper packaging and labeling.
• Train your staff on safe handling and emergency procedures.

Remember, the moment you receive the batteries, you're responsible for them. A battery that's safe in the factory can become dangerous if mishandled in transit or storage.
