CR123A Battery Safety Tips

CR123A 3.0V lithium manganese batteries are compact and powerful, but safe handling is essential for reliable performance. Store batteries in a cool, dry place away from direct sunlight, heat sources, water, and open flames. Never attempt to recharge CR123A primary cells, as charging can cause overheating, leakage, or rupture. Prevent short circuits by keeping battery terminals away from metal objects such as keys, coins, or tools. Do not mix old and new batteries or different brands in the same device, and replace batteries as a complete set when required. Avoid crushing, puncturing, disassembling, or dropping batteries, since physical damage may trigger chemical leaks or thermal hazards. Inspect batteries regularly for swelling, corrosion, or leakage, and remove damaged cells immediately. Keep batteries out of reach of children and pets to prevent accidental swallowing. Dispose of used batteries through authorized recycling channels according to local regulations to protect people, equipment, and the environment.
