![]() It has a nominal voltage of 1.5V and an open-circuit voltage of 1.8V when new, making it a suitable replacement for alkaline batteries in many applications. It is a primary (non-rechargeable) chemistry that is sometimes referred to as lithium metal do not confuse these with rechargeable lithium-ion batteries. This is a lithium-iron disulfide (Li-FeS 2) battery. Money density: 8.7 pence/g compared to 1.6 pence/g ( +448%) Other interesting comparisons can be determined like (lithium v alkaline):-Įnergy density: 233 mAh/g compared to 109 mAh/g ( +114%) That's only an improvement of 40% over common alkaline chemistry. The only common discharge profile is at 100mA, giving capacities of ~3500mAh and ~2500mAh respectively. So conspiracy theorists might think that this is to obfuscate an easy comparison of capacities. You'll notice that Energizer cunningly have two different styles of graph. I honestly thought that it would be greater. I have to admit to being surprised as to the difference in capacity. I've reviewed two relevant (and official) datasheets, one for the above lithiums and one for standard Energizer alkalines. You'll look really stupid in the middle of the Gobi desert trying to fix the buck converter in your dodgy rechargeable lithium batteries. Life saving tip: Never use rechargeable anything in survival /tactical situations as they are very unreliable. I would suggest that lithium only makes financial sense for survival /tactical situations like GPS or gun sights. Good quality alkaline batteries are good for daily use and they can be bought in industrial bulk quantities (Duracell Procell). They top the list for total storage capacity but you pay for it. ![]() They also work very well in extreme cold, although the standard advice is to keep them inside your clothing /sleeping bag. The AA type present 1.72V open circuit, and can source >4 amps shorted. And no, they don't have little bucks inside them. ![]() And yes they are a direct replacement for standard pencil batteries. The truth is that the Energizer lithiums are probably the best small batteries you can buy. ![]()
