Lithium batteries that commonly feature 3.0+ volts, should NOT be used instead of 1.5V AA batteries unless explicitly allowed by the device manufacturer. Lithium AA batteries feature physical dimensions of 14.5 mm (0.57 inches) in diameter and 50.5 mm (1.99 inches) in length - just like any other AA battery.įor many years, the typical AA battery voltage was 1.5 volts with many devices still accepting only 1.5V AA batteries. Lithium AA Batteries - Dimensions, Chemistries, and Features Lithium is a lightweight, rather reactive metal, and its chemistries are commonly used in batteries providing different features including voltage, capacity, shelf-life, drain current, and similar.Ī typical AA battery is a 1.5 volts battery and with all the lithium chemistries in use, getting "the right one" may be a somewhat difficult task.

Smartools, Maxlithium, and AmpTorrent are some of the batteries you'll have probably heard of, as well as many other brands that may be new to you. ![]() This is a great reminder that the price of an item is not always the most accurate indicator of quality. Towards the end of the test, it boiled down to one of the cheapest versus one of the most expensive brands. Todd went on to test the batteries in a "real world" environment by using handheld fans to see which would be the last one standing. Since watching Project Farm's last battery video, I have become much more skeptical about what the battery companies claim. ![]() It will probably not come as a surprise to learn that almost all of the batteries fell short of what the companies claimed they could hold. Everything from traditional chargers to various docks, to USB ports on the side of the batteries themselves.Īll the batteries were tested for capacity with an industry-standard battery tester and the results were compared to their advertised capacity. ![]() The various types of chargers also came as a surprise too. I know I have a few devices which I have to struggle with to get some brands of AA battery inside. This information brought up some interesting insights such as not all the batteries were the same size. This last point can be a deal-breaker if you plan on traveling light or don't have much space in your bag. As a bonus in this video, not only do we get the typical capacity tests, but we are also given important details such as diameter, weight, and type of charger for each battery. He also provides an update in this video to his NiMH AA battery test which has been running for the last two years.įor those who have not seen a Project Farm video before, Todd does a great job at being very methodical and fair in his testing. Thankfully for us, Project Farm over on YouTube is back to give us an answer to this question. As more and more companies enter the battery market, it can be difficult to know which brand you should carry in your camera bag. If you have no power you have no pictures. One area I would never compromise on is batteries. There are many shortcuts photographers can make when buying gear if funds are low.
