Battery, Make Your Laser Pointer Work

How to make laser pointer works? Of course is the battery! You may wonder how much power of the battery is able to supply energy for laser. Is that laser pointer not working as well as it once did? Maybe the laser us no longer as bright or it has stopped working altogether. The reason you may be experiencing this is the LR44 AG13 batteries could be running low. LR44 and AG13 are the most common laser pointer batteries. Here in this article, we will popularize knowledge of some laser batteries.

Before we contact laser batteries, we mention to the batteries at first. So what is battery? The usage of battery to describe a group electrical devices dates to Benjamin Franklin. According to Wikipedia, an electric battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. We all know that laser pointer with different shape and of course match with different battery. The most applied batteries in laser pointer are AAA, 18650, 16340, CR123A. We can see those numbers in the surface of battery. Those numbers have special meaning:

First two positions: width in mm. The second two positions: height in mm. The last two positions: shape. 0 means cylinder.

A 10440 is the same size as an AAA, though at a higher voltage (3.6v versus 1.5v). 18650 (aka 168A) - This is 65mm long x 18mm in diameter (this measurement is where it gets its name from). CR123A (RCR123A, 16340) - This is 34.5mm long x 17mm in diameter.

Take laser pointer from Highlasers for example. All the laser pointers from 1mW to 400mW laser pointer usually use two AAA batteries. AAA are the most common batteries that you can find the alternative one anywhere, such as the TV remote control device, smashing toy, horologe and so on. The most concise and public design is only designed to serve users better. The handheld laser pointer output power from 100mW to 3000mW use 16340 and 18650 batteries, which have greater storage capacity. Those batteries are able to charge for many times. While for the huge powered laser pointer, the continue working time is less than 15 seconds. The laser designator can use the CR123A, 16340 or 18650. Many of you might unfamiliar with laser designator. Laser designator creats true night vision illumination and turns your scoped rifle a real night hunter in darkness. Available with the maximum illumination distance of more than three miles in the wild, this green laser designator will provide the best illumination solution for all outdoor survival, hiking, searching, rescue and military targeting etc.

Battery are the most important element, laser cannot work without the helping of battery.

Matters need attention: Your laser pointer uses two AAA batteries. It is recommended that you use alkaline. Remove the batteries if you are planning to use it for long periods.

To install or change the batteries, unthread the cap at the clip end of the laser pointer. Insert the batteries so that the "+" ends towards the cap. Replace the cap.

What I need particularly emphasized is that the battery is forbidden to transport by air. Thus, all the online shops' products do not contain the price of the battery. Laser pointer has become a normalized product and you can buy the assigned battery in your local shop.
