The greatest danger is fire caused by improper use, charging or storage of batteries. There is potential for harmful chemical contents to come into contact with our eyes or skin and cause injury if batteries leak or begin to corrode electronic equipment.

Under normal conditions PPE does not have to be worn while handling batteries.

Other conditions such as handling an open or leaking battery would enforce using safety glasses and gloves (neoprene or rubber).

DON’T attempt to recharge a battery unless the battery specifically is marked “rechargeable.” DON’T carry loose batteries in a pocket or purse with metal objects.

There are many types of batteries. Generally, there are three main types:
  1. Consumer non-rechargeable batteries (AAA, AA, C, D, 9 volts)
  2. Consumer rechargeable batteries (AAA, AA, C, D, 9 volt, lithium type, nickel cadmium, metal hydride)
  3. Industrial batteries (lead acid batteries found in vehicles).

Tips for Battery Care

  • Always charge batteries on hard, flat, smooth non-combustible surfaces.
  • Always make sure air vents are free from obstruction. Blocked vents can create high temperatures that lead to fires or chemical releases.
  • Use the correct size and type of battery specified by the manufacturer of your device.
  • Keep battery contact surfaces and battery compartment contacts clean.
  • Remove batteries from a device when it is not expected to be in use for several months.
  • Remove batteries from equipment while household current is powering it.
  • Make sure that you insert batteries into your device properly, with the + (plus) and – (minus) terminals aligned correctly

Additional Tips for Battery Care

  • Keep spare batteries in the original retail packaging, to prevent unintentional activation or short-circuiting.
  • For loose batteries, place a strip of insulated tape across the battery's contacts.
  • If you smell smoke or burning immediately turn off the device.
  • Never disassemble a battery, as the materials inside may be toxic and may damage skin and clothes.
  • Never attempt to short-circuit a battery.
  • Disposing of a battery in fire can cause the battery to rupture. Also avoid placing batteries in water, as this may cause the battery to fail.
  • Never solder anything directly to a battery.
  • Never charge with an unspecified charger or specified charger that has been modified.
  • Never attempt to charge a battery that has been physically damaged.
  • Never reverse charge or overcharge with high currents.
  • Don't leave the battery in the charger once it is fully charged.
  • Avoid using old and new batteries together. ◦ Know where the emergency showers and eyewash stations are located.
  • Know where the fire extinguisher is located. ◦ Store batteries in a dry place at normal room temperature.
  • Extreme temperatures reduce battery performance.
