Streamlight 22112 SL-B50 Rechargeable Battery Pack 2 Pack

Product Description

The STREAMLIGHT 22112 is a two-pack of SL-B50 USB-rechargeable lithium-ion battery packs designed as a power source for Streamlight ProTac 2.0 series flashlights. Each cell operates at 3.6 volts and measures 3.26 inches in overall length, making it a direct-fit replacement for the factory battery in supported ProTac 2.0 models. The USB-rechargeable design eliminates the need for a separate charger, allowing field recharging from any standard USB power source. This pack is the correct service part for technicians and field crews who carry ProTac 2.0 lights as part of their standard kit.

This two-pack is suited for any professional who depends on ProTac 2.0 series flashlights during daily operations, including HVAC technicians, electricians, plumbers, and other tradespeople who use the ProTac 2.0 platform as a work light. Keeping a spare set on hand reduces downtime between charges on long shifts or multi-job days. The pack is sold as a quantity of two units per order, making it practical for maintaining backup power at the shop or in a service vehicle.
