But don’t worry; we’ve got you covered with this buying guide, where we’ve mentioned some important factors that you must keep in mind while shopping. Let’s check them out. 

1. Battery Life Of Lithium Batteries 

Let us ask you a question– what are cr123a batteries popular for? Of course, they are much sought-after for their exceptional battery life and extended durability. So, the first thing you must check is the battery life the brands offer with their battery sets. 

In this regard, always check the power rating mentioned by the brand in the description of the product. While some prefer batteries with 1,500 mAh capacity, others opt for a battery rating of 1,650 mAh . Ideally, going for batteries with high ratings is the best bet because you won’t have to replace them soon. 

Many alarm manufacturers mention the power rating and the battery size that are compatible with their devices, so make sure you check the instruction manual.

3. Budget

Rarely do cr123a batteries come in single packs; most brands sell them in multiple packs ranging from a two-piece to 50-piece options. Make a budget so that you don’t spend more than required. 

And when purchasing batteries, weigh the price with the capacity offered because some brands offer more units at a lesser price.
