Frequently asked questions about operating your Streamlight Torch

Here are some commonly asked questions regarding the operation and usage of Streamlight torches. If your question is not listed below, or not available in the enclosed documentation with your product, please do not hesitate to contact PSL for more information.

Q: Can I use rechargeable CR123 batteries in any of the Streamlight flashlights?

A: No. Streamlight products are optimized and the components can be damaged or destroyed by the use of anything other than the recommended battery type. The use of improper or substandard lithium batteries can be especially dangerous.

Q: Do I need to condition my lead-acid battery; drain it out and fully recharge it?

A: No. Routinely running the lamp until it extinguishes will drastically shorten the life of the battery.

Q: Is there any way to prevent the rechargeable Ni Cd battery from developing a memory?

A: Research has shown that the "memory effect" is a rare phenomenon and is almost nonexistent in high-drain applications such as flashlights.

Here are some useful tips to help prolong the life of Ni Cd batteries:

  • The light should be returned to the charger when it is not in use
  • It should never be run until the battery is completely exhausted
  • Return the flashlight to the charger when it begins to dim

Q: Can I use rechargeable batteries with LED lights?

A: Streamlight does not support the use of batteries other than those specifically listed in the instructions. Normally the lamps and current regulators are designed for a specific type of battery, and using other batteries often results in poor performance, either low output or extremely short lamp life, depending on the battery types involved.

Q: Can I use the same charge cord for different chargers?

A: Generally yes. Streamlight charge cords use a common connector. The exception to this is the Ultrastinger fast charge systems that must use either vehicle 12V DC or the heavy duty AC charge cord which is supplied with the system.

Q: The red light on my steady charger does not light. What could cause this?

A: First, see if there is power to the charger itself. Second, check to be sure that the flashlight is properly inserted into the charging system. If the red light still does not light the flashlight and charger should be returned for repair.

Q: What causes the red LED on the Strion charger to flicker?

A: As the battery approaches a fully charged state it is normal for the charger LED to alternate between lighting steadily and blinking. This process may take as long as 15 minutes to one half hour and does not indicate a charging problem.

Q: Can I charge a Strion with my Stinger charger holder?

A: No. The Stinger and the Strion are different sizes and their battery chemistries and charging systems are completely different.

Q: How can I tell when my flashlight is fully charged?

A: Follow the guidelines in the instruction booklet included with the flashlight. Some products have a red and green light combination (Litebox, Vulcan). In that case green indicates a charged condition. Flashing red LED’s on the Stinger (fast) and Strion chargers indicate a charged condition.

Q: I have the steady charger. Will the fast charger shorten the life of my battery?

A: No. Batteries have an expected number of charge/discharge cycles (the number varies by the type of battery). Streamlight fast chargers safely revert to a maintenance charge rate after the battery has been charged.

Purchased 4x 18650 rechargable batteries and a charger days before Christmas.. Delivery was awsomely fast considering it was just before the holiday shut down.
Batteries were not fully charged but work fine in the torches we bought them for.
