Streamlight 22101 Rechargeable Li-ion Battery 2600mah

Product Description

The STREAMLIGHT 22101 is a rechargeable lithium-ion battery designed as a direct replacement power source for compatible Streamlight flashlights and lighting tools. Rated at 3.7 volts with a capacity of 2600 milliamp-hours (mAh), this single-cell battery delivers sustained runtime between charges. It measures approximately 4.25 inches in length and weighs 0.14 pounds, making it a compact and lightweight component. Licensed electricians, HVAC technicians, and field service pros who rely on Streamlight-brand lighting equipment keep this battery on hand to restore full runtime performance to their primary work lights without replacing the entire unit.

This battery is suited for trade and industrial use where dependable, rechargeable lighting is required. It fits Streamlight models that specify the 22101 battery, covering handheld flashlights used in residential and light commercial service environments. The lithium-ion chemistry maintains a stable discharge curve, reducing the voltage drop-off common with older NiCd or alkaline alternatives. Technicians working in confined spaces, attics, crawlspaces, or panel rooms benefit from the extended capacity this cell provides during longer service calls.
