  • Don't overcharge. Overcharging can cause the battery to rupture, overheat, catch fire, or even explode.
  • Don't damage. An impact that causes a dent or puncture in the battery could result in a dangerous situation. Don't charge a damaged battery. Discard swollen batteries
  • Stay nearby. Don't leave a charging battery unattended.
  • Store properly. Avoid storing your battery in direct sunlight, in extreme heat or cold, or under heavy objects.
  • Allow air. Don't charge near combustible materials.
