KW208 can test all 12V 100-2000CCA batteries including regular flooded, AGM flat plate, AGM spiral, or gel batteries. 【Automotive Car Battery Tester】 As one of the most cost-effective products of KONNWEI, it's a perfect Christmas gift.Sometimes instead of the CR, a brand will use letters that are associated with their name, like DL is the Duracell brand. So, why all the names?īasically, it’s down to the preference of the brand. For this reason, each of the batteries, and more specifically the CR123 and the CR123a are 100% interchangeable. For this particular sized battery, the ‘a’ makes no difference. If you search for 123 lithium batteries, you will often find a selection of CR123s or DL 123As. In actual fact, in the case of these batteries, there is no difference. So what’s the difference between CR123 and CR123a battery ? They are lithium batteries and have 3 volts. They are all 16.5mm in diameter and 34mm in length. Some brands will choose to put an a/A on the end to represent the A cell. So any 123 battery is 1 2/3 of an A cell battery. What does cr mean in batteries? The C stands for Lithium and R for round. The CR123 and CR123a are both logically named. So, whether you’re a professional photographer looking for a reliable power source for your camera or a homeowner looking to power your home security system, read on to find out which battery is the best fit for your needs. We’ll also take a deep dive into their technical specifications, including their voltage and capacity ratings, to help you make an informed decision. So, which one is the best for your device? In this article, we’ll take a closer look at the CR123 vs CR123a batteries and explore their pros and cons. While they may seem similar, they actually have a few key differences that can make a significant impact on your device’s performance. If you’re in the market for a new battery for your device, you may have come across the CR123 and CR123a batteries. Amazon’s Best Selling Battery Power Banks!.Tips for storing and handling batteries.So what’s the difference between CR123 and CR123a battery?.Are the CR123 and CR123a batteries interchangeable?.That does sound like pretty good life to me. This is just what I see on mine, but it sounds similar to you. Your actual readings might vary-I'm not sure how calibrated mutlimeters are and I've certainly never compared mine to anything. I imagine this complicates percentage-based reporting due to both the non-linearity but also the fact that if battery checkins aren't frequent enough and the battery drains quickly, it might not even have time to catch this happening. Lithium battery life is harder to estimate because the decline isn't linear: it stays at a fairly high voltage most of its life, then sharply declines when it's near the end. By the time they get close to 3.0V, they're practically dead in my experience, and if I find one that's around 2.7-2.8 V (as I do on occasion), it's usually been dead for a while before I noticed. In my experience, my multimeter reads new lithum batteries at a bit above 3.2V when new. So I have a general question - how low can the voltage be on a CR123A battery without compromising the function of a contact sensor? OTOH, 3.04V doesn't seem that far away from 3.28V and Hubitat did report it as being 100%, and maybe just removing the sensor and replacing the battery fixed the reed switch for a bit.
