Questions about this item

How much heat or power draw should I expect from the 3.6V 2600mAh cells during extended use?

What charger or device do I already need to use these 74175 batteries?

They are direct replacements for Streamlight 74175 packs and work in Strion Switchblade, Strion LED, Strion HL, Strion HPL, Strion DS models, ProTac HL USB lights and Twin-Task USB headlamps.

Will the 70.3 x 20.6 x 20.6 mm size fit my older Strion flashlight without modification?

Yes, the dimensions match the original Streamlight 74175 battery, so they slide into the same compartment on all listed Strion and ProTac models.
