What is the Best CR123A Battery for Alarm Systems?

This section presents a comprehensive comparison of the top-performing CR123A batteries tailored for alarm systems. The ensuing table gives you each product specification such as battery type, milliampere-hour (mAh) rating, and voltage specifications.

CR123A Batteries For Alarm Systems Buying Guide

Nowadays, most household electronic products and modern gadgets are dependent on CR123A batteries since they are a portable power source. Some devices that require CR123A batteries are music players, cameras, high-density flashlights, and home security systems. Moreover, these batteries are extremely efficient and capable of delivering high performance while being small and compact. 

However, each battery type delivers a different performance, which makes it tough to choose the right one for the alarm system. As such, we have listed a few factors that can help you find the best batteries according to your requirements. 

1. Battery Life

While choosing CR123A batteries for the alarm system, you should always ensure that they are durable and have long battery life. Most brands provide all the necessary information related to the battery life on the packaging. As such, you should always check the packaging to see which brand offers a longer battery life. 

A longer-lasting battery is not only durable but also great value for money since you don’t have to replace it frequently. One of the best ways to check a battery life is to see the power rating score on the packaging. Batteries with high power rating scores can serve a longer lifespan without causing any hazard or harm to your home appliance.

In fact, some devices mention which power rating score batteries they require to run efficiently. For example, high power rating CR123A batteries are ideal for Arlo cameras. Thus, you should always choose the one that is compatible with your device. 

2. Affordability

Apart from being durable and long-lasting, you should ensure that the batteries are affordable. If the brand sets a high price for the batteries, you might not be able to purchase multiple batteries for your home appliances and electronic products. Nevertheless, you should never compromise by purchasing a cheaper battery with a poor power rating or short battery life. 

But, if a brand offers more units for a slightly lower capacity, you take the deal since you can power more devices through one set of batteries. The excess batteries that are left out can be stored and used later on when old batteries run out. Such sets are actually more affordable since you can purchase a bunch of batteries at an affordable price. 

3. Shelf Life

Another important factor to consider is the shelf life of the battery. This is especially important if you are planning to store excess batteries for a longer period. In general, CR123A batteries are well known for having a long shelf life since they don’t go out easily. As such, the backup supplies can stay ideal on the shelf for about 10 years or so. 

In addition, high-capacity batteries are capable of lasting for a decade without having any drops in performance. On that note, it is advisable to check the shelf life of the batteries if you are planning to stock them for a long time. Some brands even offer rechargeable batteries, but they tend to be a bit more expensive than regular CR123A batteries. 

Just ensure that the excess units are stored in a cool and dry area since excess heat and humidity can damage the cells within the battery. 

4. Eco-Friendly Design

Lastly, you should always consider purchasing an eco-friendly product that doesn’t harm or cause any harmful pollution. Most brands prefer to design eco-friendly batteries since they cause less pollution and help to bring down e-waste significantly. Instead of purchasing use-and-throw batteries, you can always opt for rechargeable batteries that can last for a long time. 

Normally, a regular dead battery contains harmful chemicals such as lead, lithium, cadmium, and more, which can be hazardous to your health as well as the environment. Fortunately, a lot of brands are now shifting to more sustainable and eco-friendly alternatives.
