Batteries Dos and Don’ts

  • Do keep spare batteries in a cool dry area.
  • Do keep batteries out of the reach of small children, who may be tempted to swallow them. Should such an accident occur, promptly take the child to a doctor.
  • Don’t dispose of batteries in fire or heat above 100° C (212° F) - the battery can explode or leak and cause personal injury.
  • Don’t recharge - the battery can explode or leak and cause personal injury.
  • Don’t mix with used or other battery types.
  • Don’t expose batteries to water.
