High-Capacity 3.7V Li-ion Battery 4-Pack

This four-pack of Kastar 74175 lithium-ion cells delivers 3.7 V and 2.6 Ah each for Streamlight flashlights and headlamps. The 9.36 Wh rating provides extended run time for compatible Strion and ProTac models. Users who rely on their lights for daily professional use gain a ready supply of fresh power.

Verify Your Light Model Before Ordering

Check that your device accepts the Streamlight 74175 battery; the pack fits Strion Switchblade, Strion LED, Strion LED HL, Strion HPL, Strion DS HPL, Strion DS HL, ProTac HL USB flashlight and ProTac HL USB headlamp. Confirm the physical size of 70.3 x 20.6 x 20.6 mm matches the battery compartment. Buyers with other Streamlight series or non-Streamlight brands will need a different cell.

Drops Into Compatible Streamlight Lights

Each cell includes built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection and meets UL1642 and CE safety standards. The 2600 mAh capacity frees you from frequent swaps during long shifts. No external charger is included, so your existing Streamlight charging cradle or USB cable handles recharging.

Questions about this item

Does the pack include a charger or only the four 74175 batteries?

The pack contains four 74175 lithium-ion batteries and no charger; a compatible Streamlight charger must be purchased separately.

Why is the voltage listed as both 3.7 V and 3.6 V on the same page?

3.7 V is the typical nominal rating used in the product title, while 3.6 V is the manufacturer's specified nominal voltage for the 2600 mAh cells.

Will the 9.36 Wh capacity actually power a Strion Switchblade longer than the original cell?

Each 2600 mAh cell stores 9.36 Wh, matching the original Streamlight 74175 specification, so runtime will be equivalent to a fresh OEM battery.
