Sure, some flashlight geeks have their own idiosyncratic favorite brands, but the SureFire CR123A remains the most widely loved and commonly recommended lithium primary in this category. Many enthusiasts and our own experts reach for $21 per box of 12 SureFire CR123A batteries every time. Why bother with the reduced capacity of Li-Ion CR2032 and the bulk and bother of a battery charger when you can just buy a few extra lithium primaries and call it a day?ĬR123A is another common battery size outside of the AA family, often used in outdoor-oriented torches and weapon lights (eg. Many firearm optics use the CR2032 coin cell format, which is a prime example of an application where there’s really no point in looking for a rechargeable. The best CR2032 batteries are the $12 per box of 10 Sony CR2032, and just a handful of these tiny, long-shelf-life batteries will keep many popular powered rifle optics going for decades. Which means you save money through less frequent battery changes and, because those products don’t kill batteries too quickly, they’re a backup source in case you need to cannibalize for more power after an emergency.Ī favorite of hardcore flashlight and camera enthusiasts, these batteries are the benchmark that all other lithium primaries are measured against. There is an Energizer Ultimate Lithium 9V battery ($30 per pair), however, and we particularly like the long life of lithium batteries in 9V because many always-on but low-power-trickle products take that size (eg. Unfortunately, that means we can’t recommend any lithium products in this category - use plain alkalines in the meantime, while moving your gear away from C and D sizes and/or embracing rechargeables. All of the batteries in this range that we found appear to come from Chinese factories with questionable quality variances. So while there are a number of lithium primary options on the market, there are none from makers that we trust. The market for C and D cell battery sizes isn’t nearly as robust as it is for the other sizes in this review. That’s partly due to the more complicated nature of building lithium-based batteries (which goes hand-in-hand with their rare chance of catching fire). Unlike most of our survival gear reviews, this category doesn’t yet require a lot of deep field testing - mostly because there aren’t many worthwhile contenders to begin with. Even though you pay about 3X the price of high-end alkalines for that major boost in capacity and lifespan, lithiums are worth it for emergencies and always our preferred choice. Quality lithium batteries have over double the capacity and almost double the lifespan of high-end alkaline batteries, so you can store more electricity in a smaller, longer-lasting package.

And, thanks to modern battery tech, you can save money and reduce how much you throw in a landfill by skipping over the common and cheapest alkaline disposables (eg. Single-use batteries - officially called ‘primary’ batteries - have a role in your emergency kit even if you’ve tried to standardize your gear around multi-use ones.
