Streamlight Replacement Battery

Another Bright Idea in Law Enforcement

Streamlight Jr.® LED replacement batteries light the way.

Don't let the name "Junior" fool you'. The Streamlight Jr.® LED lights may be lightweight and compact, but the light they produce is anything but small. C4® LED technology emits a blast of bright light with a far-reaching beam that you'd never expect from a flashlight this size. And the Jr. LED series of lights are big on dependability too. They run up to 4 continuous hours on two "AA" alkaline batteries.

It’s obvious that Streamlight® batteries are a very big deal, which means Streamlight® replacement batteries are a big deal too. And we give those Streamlight® replacement batteries the attention they deserve with both great selection and service.

By the way, when powered by two "AA" alkaline batteries (included) or two "AA" lithium batteries the Jr® unleashes 1 watt C4® LED, 50,000-hr. LED, and up to 3800 candela (peak beam intensity) and 85 lumens measured system output. With a AA Alkaline or AA Lithium battery inserted, the light on high provides 2,750 candela, 150 lumens and a 105-meter beam distance, with runtimes of 1 hour and 20 minutes for a AA Alkaline and 4 hours, 15 minutes with a AA Lithium battery.

Notably, there are numerous other differences between lithium and alkaline batteries, starting with popularity. Alkaline batteries account for 80 percent of all U.S.-manufactured batteries. They are made in standardized cylindrical forms interchangeable with zinc-carbon batteries. The basic voltage of a fresh alkaline cell is 1.5 V, while the capacity of an alkaline battery is strongly related to load. They are a type of primary battery that is dependent on the reaction between zinc and manganese oxide. They are like small power plant that converts a chemical reaction into electrical energy.

Further, each alkaline battery has two terminals — positive and negative terminal. That chemical reaction inside the battery produces electrons, which gather at the negative terminal of the battery. However, unless the negative terminal is connected to the positive terminal, the chemical reaction stops and no more electricity is produced. That explains why an alkaline battery can sit in a drawer for a long time and keep its power for when needed. If the battery is not used, it will not wear out in a short period of time.

Lithium batteries use higher energy density cells to often provide great performance. Generally, they’re excellent, although chemistry, cost, safety characteristics and performance do vary across types. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V (comparable to an alkaline battery) to approximately 3.7 V. Lithium-ion and lithium metal polymer are rechargeable batteries, where ions move between the anode and the cathode, using an intercalated lithium compound or metallic lithium as the electrode material.

Regardless of these facts, Streamlight replacement batteries — are special.
