Lithium-ion batteries<\/em><\/p>\n\n\n\nAs mentioned earlier, batteries come in various sizes, and lithium-ion models are no exception. And some LED flashlights can accommodate different kinds of lithium-ion batteries. So, let’s look at these different types.<\/p>\n\n\n
26650 Li-Ion Battery<\/h3>\n\n\n
This battery size is the biggest on this list. Further, 26650 lithium-ion batteries are compatible with flashlights, known as a soda can lights.<\/p>\n\n\n\n
However, these flashlights are not ideal for everyday use due to their large sizes. <\/p>\n\n\n\n
But they dish out incredible outputs. In addition, some 26650 batteries feature a high 5000 mAh capacity, and others may even provide higher.<\/p>\n\n\n
21700 Li-Ion Battery<\/h3>\n\n\n
Unlike the 26650 models, 21700 Li-Ion batteries feature more compact sizes. Also, they don’t sacrifice power to achieve smaller forms.<\/p>\n\n\n\n
Additionally, flashlights ranging from heavy-duty to everyday carry lights can use 21700 batteries. And 5000 mAh is the maximum capacity for 21700 Li-Ion batteries.<\/p>\n\n\n
18650 Li-Ion Battery<\/h3>\n\n\n
Currently, 18650 Li-Ion batteries are the most widespread for LED flashlights. Although their maximum capacities are 3500 mAh, these smaller batteries are ideal for hand-held, everyday carry, and tactical flashlights.<\/p>\n\n\n\n
In addition, some advanced 18650 Li-Ion batteries have built-in micro USB charging ports. This innovation is perfect for flashlights without rechargeable features. <\/p>\n\n\n\n
So, you won’t have to deal with battery chargers, and your flashlight will enjoy longer run times.<\/p>\n\n\n
14500 Li-Ion Battery<\/h3>\n\n\n
These battery sizes are incredibly similar to AA models. Interestingly, 14500 Li-Ion batteries can fit everyday carry and pocket flashlights. However, the highest mAh you may find for these sizes is 800.<\/p>\n\n\n
16340 Li-Ion Battery<\/h3>\n\n\n
Lastly, the 16340 Li-Ion battery is shorter but wider than the 14500 Li-ion battery. These battery sizes are similar to CR123 lithium batteries and can easily power pockets and everyday carry flashlights. <\/p>\n\n\n\n
Moreover, 700 mAh is the highest capacity from these batteries.<\/p>\n\n\n
