Flashlight Battery Safety – You MUST read these Warnings and Instructions before using or charging your batteries!

WARNING: HANDLE AND STORE BATTERIES PROPERLY TO AVOID INJURY OR DAMAGE

BATTERIES CAN BE DANGEROUS!

Most battery issues arise from improper handling of batteries, and particularly from the use of damaged or counterfeit batteries. Please review the information below to avoid serious injury and/or damage to your property.

Alkaline Batteries

  • For those lights with hazardous location safety approvals for explosive environments please be advised that the safety approval is only valid for the specified battery type manufacturers and, where applicable, brand names that are displayed on the flashlight and/or instructions sheets that are supplied with the flashlight. The use of other battery technologies may reduce the performance of the flashlight, expose the user or others to serious injury and will invalidate the safety approval.
  • Always read the battery manufacturer’s recommendations for the appropriate use of the battery technology/brand prior to using the flashlight.
  • When replacing the batteries, replace all the batteries at the same time. DO NOT mix battery brands. DO NOT mix old and new batteries. Always insert batteries correctly with regard to polarity (+ and -) marked on the battery and equipment.
  • DO NOT change batteries in a hazardous location.
  • DO NOT use batteries beyond their expiration date.
  • Remove batteries from equipment if it is not to be used for an extended period of time.

Lithium Batteries

  • By purchasing Lithium Polymer and Li-ion battery, the buyer assumes all risks associated with lithium batteries. If you do not agree with these conditions, please consider Ni-MH batteries or return the battery immediately before use.
  • Use only Panasonic™, Energizer™, Duracell™, or Sanyo™ batteries.
  • DO NOT mix old and new batteries.
  • DO NOT mix battery brands/types.
  • When replacing batteries, replace all batteries at the same time.
  • DO NOT open batteries.
  • DO NOT dispose of in fire.
  • DO NOT heat above 75°C.
  • DO NOT expose batteries to water.
  • DO NOT recharge.
  • Insert batteries correctly with regard to polarity (+ and -) marked on the battery and equipment.
  • DO NOT use batteries beyond their expiration date.

Rechargeable Batteries

  • Hazardous location safety approvals for explosive environments are only valid for the Pelican battery pack that is supplied with the flashlight.
  • For replacement battery packs only use the approved Pelican battery pack for the model of the flashlight that you are using. The use of other battery packs will reduce the performance of the flashlight, exposure the user or others to serious injury and invalidate the safety approval.
  • Flashlights should only be charged in a non-hazardous location.
  • Flashlights should only be charged using the Pelican charger base that is supplied with the flashlight.
  • Flashlights should be charged and operated between the temperatures shown in the table below.
battery type charge temp operating temp
lead acid –20°C to 50°C
(–4°F to 122°F)
–20°C to 50°C
(–4°F to 122°F)
Ni-MH 0°C to 45°C
(32°F to 113°F)
–20°C to 65°C
(–4°F to 149°F)
Li-Ion 0°C to 45°C
(32°F to 113°F)
–20°C to 60°C
(–4° F to 140°F)
  • DO NOT charge rechargeable alkaline batteries while they are still in the flashlight. Charging the alkaline batteries while they are still in the flashlight can cause internal gas or heat generation resulting in venting, explosion or possibly fire which could cause serious injury or property damage.
  • Deep discharge* of the rechargeable battery may cause batteries to vent potentially dangerous gasses and electrolytes.
  • It is advisable to condition* batteries every 3 months. Failure to do so will decrease battery life. Leaving the product unused for long periods of time will decrease battery life. Withdrawal of the charger from the product prior to a 'READY' indication will result in inadequate charge.
  • WARNING - DO NOT use Ni-MH rechargeable battery packs for longer than 3 years or 500 charge/discharge cycles, whichever comes first. Using the Ni-MH rechargeable battery packs for longer than 3 years or 500 charge/discharge cycles will reduce the performance of the flashlight and expose the user to serious injury or property damage
