Lithium : Lithium batteries work even better than alkalines. They last much longer, have an epic shelf life, don’t discharge as much power when not in use and can cope with extreme temperatures. While normal alkaline AAs struggle below 0°C, lithium batteries will operate down to -40°C. They can also be up to 9g lighter than the equivalent alkaline AA battery, which counts when you have something powered by four AAs. The only negative? They’re significantly more expensive.
