Replacement Battery for Streamlight MicroStream

This Cameron Sino battery replaces the original power cell in Streamlight MicroStream flashlights. It delivers 800mAh at 3.7 volts using nickel-zinc chemistry. The pack measures 53.50 by 14.60 by 14.40 millimetres and weighs 23.0 grams. A built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits.

Capacity and Runtime Expectations

The 800mAh rating provides 2.96 watt-hours of energy for typical indoor flashlight use. Runtime scales with the light's output setting; higher modes will deplete the charge faster while lower modes extend it. The nickel-zinc cells reach full performance after two or three complete charge and discharge cycles. The pack is not suited for devices that demand a higher voltage or a different form factor.

3.7 Volt Nickel-Zinc Chemistry

This cell operates at a nominal 3.70 volts with nickel-zinc composition, a voltage level that matches the original MicroStream requirement. Using a charger or device designed for a different chemistry or voltage can damage the pack or create a safety hazard. Verify that your flashlight specifies 3.7 volts and the 66321 part number before installing.

Questions about this item

Will this 3.7 V, 800 mAh nickel-zinc cell run in my existing Streamlight MicroStream without any modification?

Yes, the 66321 is a direct replacement for the Streamlight MicroStream and the fully decoded chip works exactly like the original battery.

How can I confirm the battery is performing correctly once installed?

After two or three full charge and discharge cycles the pack should reach its rated 2.96 Wh capacity and the flashlight will run for its normal duration.

Does the package include a charger or only the single 23.0 g battery?

Only one replacement cell is supplied; a compatible charger must be purchased separately.
