Lithium batteries are more popular today than ever before. You'll find them in your cell phone, laptop computer, cordless power tools, and even electric vehicles. However, just because all of these electronics use lithium batteries doesn't mean they use the same type of lithium batteries. We'll take a closer look at the six main types of lithium batteries , revealing pros and cons, as well as the best applications for each. LMO or Lithium Manganese Oxide LCO batteries were standard in small portable electronics such as mobile phones, tablets, laptops, and cameras. However, they are losing popularity to other types of lithium batteries due to the high cost of cobalt and concerns around safety. LFP or Lithium Phosphate LFP battery cells have a nominal voltage of 3.2 volts, so connecting four of them in series results in a 12.8-volt battery. This makes LFP batteries the most common type of lithium battery for replacing lead-acid deep-cycle batteries. LCO or Lithium Carbon O
