Go the rechargeable route and replacing batteries is much less of a drain on your wallet and the environment. According to recycler Battery Solutions, if you opt for disposable, single-use batteries, you’re contributing to the estimated 3 billion of them that end up in landfills every year. Before you know it, you’re reaching for a tiny screwdriver to pry open the battery cover on toys, the remote control, or dozens of other power-hungry gadgets around the house.

Please be careful when considering the purchase of a charger that comes with a lower than average price. Most smart chargers will terminate at or slightly under 4.2… but accidents (and failures) can occur. Similarly, charging also needs to be kept an eye on, since they must not charge above 4.2 volts. Because unlike a protected LiCO cell, (or unless your light contains a protection circuit) the battery will not shut off before the voltage can slip into the danger zone! If it does on a continuous basis, it could be damaged, resulting in a failure to charge…or worse. So if an IMR is being used in your favorite light, you must monitor its discharge, and be careful not to drain it below 3.0 volts. The ‘big’ warning concerning the use of unprotected cells from flashlight experts, is always centered around charging and discharging. The IMR cell will charge faster, and has a higher discharge rate, making it more suitable for devices requiring a higher current to operate. This is what defines an IMR as “safer” than a LiCO (cobalt) cell. But their internal resistance stays low over time. As mentioned earlier, they don’t have the capacity of a cobalt-based cell. It’s actually due to their non-protection that make IMR’s popular. Most of the time, an IMR battery will NOT have a protection circuit, although some companies do put them in their IMR cells. Its width is 18mm, whereas the girth of a 16340 (or CR123 primary) is normally 16.5mm. A 18350 is a difficult fit for most flashlights due to its thicker diameter. IMR batteries are produced in most of the popular lithium sizes 16340, 14500 & 18650. Regarding those tempting mAh figures… click here to read an important post on this very topic! Shapes and Sizes This however does not diminish the ability of the IMR battery to perform just as well as the cobalt cell. In the case of IMR, those figures are often cut in half, since capacities of Li-MN cannot reach what lithium cobalt is capable of. When searching for Lithium-ion batteries as a power source, it’s often those high mAh figures that lure us in. In this case, it’s Manganese Oxide, instead of Cobalt Oxide, (lithium cobalt or LiCO) which is what the majority of our lithium-based cells are comprised of. Without attempting to translate a scientific definition, an IMR battery uses a different form of oxide for his chemical makeup.
IMR refers to Lithium-ion Manganese Rechargeable, or Li-MN (lithium manganese). Is IMR An Acronym?įirst off, IMR is merely a product code. Anyway, the topic here is regarding IMR batteries. I’m not a smoker and don’t pretend to know anything about them, but I understand they run fabulously on Li-ion cells. The recent popularity of e-Cigarettes, has also broadened their reach.
With the advances in technology of LED flashlights, Lithium-ion batteries have become more mainstream. With the various types and sizes of batteries available these days, consumers are getting confused, and rightly so!
