Streamlight Flashlight Batteries — Q&A

What kind of batteries do Streamlight flashlights use?

Many Streamlight flashlights use a Nickel Cadmium or Lithium-Ion battery, allowing for powerful illumination and recharging capabilities. But ultimately, it depends on the model of your Streamlight flashlight.

How long do Streamlight batteries last?

Much like battery type, Streamlight battery longevity depends on both the kind of battery and the flashlight model. Streamlight’s rechargeable batteries have been known to last for over a decade.

Do Streamlight products have a lifetime warranty?

Streamlight flashlights come with a lifetime warranty from Streamlight. However, Streamlight batteries don’t. Streamlight batteries have a 2-year warranty with proof of purchase; improperly handled batteries do not qualify for the warranty.
