--------------------------------------

We have received hundreds of emails asking for a light which uses a 10440 cell battery.  We now have the ReyLight Copper AAA/10440 light which works with both cell variants. 

Why use a 10440 Lithium cell? Higher voltage = Much brighter & also rechargeable 

 


Warning: Dont use this cell in another AAA or Maratac light you have as it will void you warranty and destroy the light. Misusing or mishandling a lithium-ion battery may cause a FIRE or EXPLOSION which can result in INJURY or DEATH. You MUST read the safety warnings and resources before purchasing, using, and/or handling batteries.

  • Only use in a device which as a smart BMS built in
  • Note the length of the cell to ensure it will work in your application as well
  • If your flashlight were the only device into which a buyer might attempt to insert the battery, there’d be no issue. However, since it is a great battery, others may buy it for other purposes. They need to be warned of its limitations.

Peanut beast 10440 battery

I purchased this battery to extend the runtime on my titanium peanut beast. It definitely did the job!! I'm probably going to purchase another one to have as a spare. County Com is the best.

Great LIttle LIght

This light is so handy, remarkably bright, and inexpensive to operate with the rechargeable battery. That battery is responsible for the additional power this light provides. But as a bonus, any AAA battery can be used, although with a reduced output.
