Please make sure to check the Mah capacity of a rechargeable battery before you purchase. Conversely, quality NiMH batteries produce 2500 mah of capacity (sometimes more) and outperform the best alkaline batteries by up to 50%. These discount store batteries seldom perform as well as alkaline batteries and usually convince the user they aren't worth the trouble. Most widely available rechargeable batteries (think discount store) have small milliamp-hour (mah) capacities (1200 - 1600). Often times we talk to someone who has unknowingly purchased older/low capacity batteries and found the battery life to be extremely poor. Many people have had bad experiences with rechargeable batteries.
Fortunately, almost all current production models have a shut-off voltage of about 1 volt per cell and are compatible with NiMH batteries. This makes Nimh batteries incompatible with several models manufactured prior to 2011. With NiMH batteries providing just 1.2 volts/cell, they produce an aggregate voltage of only 4.8 volts. Many of these 6-volt systems constantly monitor the voltage and automatically shut the camera off when the voltage dips to around the 5-volt level. It is very common for a camera to use 4 batteries, or essentially a 6-volt system (4 X 1.5volts).
Most cameras are designed around a 1.5 volt/cell scenario. However, the 1.2 working voltage does present a problem for use in some cameras. However, they quickly decrease to a working level of 1.2 volts, which they are consistently able to deliver for the rest of the usage cycle. In contrast, once NiMH batteries have been conditioned (Fully discharged through 2-3 charging cycles) they can be charged at any point in the usage curve and won't develop memory as quickly.įully charged, NiMH batteries produce about 1.4 volts. If Ni-cad batteries were used and not drained completely, they would often lose a portion of their capacity. As you may recall, Ni-cad batteries were widely criticized for developing “Memory”. NiMh rechargeable batteries were introduced as the successor to Nickel Cadmium (Ni-cad) rechargeable batteries. Nickel Metal Hydride (NiMH) Rechargeable Batteries You can learn more about lithium batteries here. In general and for most uses, we love lithium batteries for trail cameras and here you will find some of the best batteries for cameras. The downside is lithiums are quite a bit more expensive, and just like alkalines, they are also headed for the landfill after only 1 use. If you’re backpacking in to change out several cameras this is very advantageous. Inserting “AA” lithiums into aftermarket sleeves brings the overall diameter up to that of a “C” cell and makes for a perfect substitution.Īnother benefit of using the AAs is they are substantially lighter and take up far less space than the larger “C” cells. Fortunately, AA’s and C’s measure exactly the same from tip to tip. However, if your trail camera requires “C” cells you can benefit from the extra voltage lithiums offer. For anyone who operates a “D cell” based camera, you’re out of luck.
One aspect of lithium batteries that can be interpreted differently is they are currently only available in AAs. Lithium batteries will increase the amount of time your camera can stay in the field, many times by multiple months.ĭue to their chemical makeup, lithiums are also not affected by cold weather. In addition, starting out with the higher 1.6 voltage is like installing an auxiliary gas tank in your vehicle. We are noticing about a 10% increase in flash range when using lithium bats. Just as decreasing voltage produces weaker flash characteristics, increased voltage produces a stronger flash with brighter pictures. To start, lithium batteries produce 1.6 volts/cell, or as we like to say “They run hot”. Lithium batteries offer some very interesting benefits. South Georgia & South Sandwich Islands (USD $).Some of these companies make perfectly serviceable cells as well, and others appear to be prone to outright intentional misrepresentation, such as absurdly (and impossibly) inflated capacity ratings and advertised-but-missing features like protection circuits. This list includes names like GTF, GTL, TrustFire, and Efest. The names on this list might be familiar to anyone who's shopped for high-drain 18650 cells in the past, but all of these also produce batteries in the AA form factor. They don't come close to the ratings, and they show incredibly steep capacity drop-offs even at the smallest loads. These rechargeables are often rated as high-drain with high (often fraudulently so) Ah capacity ratings. Rather than listing a bunch of low-profile brands (like UltraFire) with the same set of problems, we're grouping these together as well. Those two things are functionally equivalent.
The 14500 is a whole class of batteries, and dozens of brands, that are either terrible or are counterfeited so frequently that attempting to buy one leaves you with a terrible battery.
