Flash Light FAQ

Flash Light FAQ

Can I use rechargeable batteries with LED lights?
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; using other batteries often results in poor performance — either low output or extremely short lamp life, depending on the battery types involved.

Can I use rechargeable CR123 batteries in any of the Streamlight flashlights?
No. Streamlight products are optimized for a specific battery 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.

Can the Streamlight Jr. Luxeon use batteries other than alkaline?
Nickel-metal hydride AA replacement rechargeable batteries seem to work OK. However, since the product was designed for alkalines, and we cannot possibly test all of the aftermarket replacements, we cannot recommend the use of any batteries other than alkalines.

Do I need to condition my lead-acid battery — drain it out and fully recharge it?
No. Routinely running the lamp until it extinguishes will drastically shorten the life of the battery. Lead-acid batteries need to be fully charged. The higher the average charge on the battery, the longer it lasts. Deliberately draining a lead-acid battery will quickly destroy it.

How can I tell which model Survivor I have? Which model uses which battery?
Some Survivors have model information listed on them. See the retail-price list on this Web site for replacement batteries. Numbers on the older batteries may not be current.

Is there any way to prevent the rechargeable NiCd battery from developing a memory?
Research has shown that the “memory effect” is a rare phenomenon and is almost nonexistent in high-drain applications, such as flashlights. Here as some tips to help prolong the life of NiCd 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.

What is the part number for my battery? I found several numbers on the shrink-wrap.
See the retail-price list on this Web site for replacement batteries. Numbers on the older batteries may not be current. Multiple numbers on the same battery are for regulatory requirements.
