Canon’s EOS digital camera range uses four types of battery. Most of the batteries in the EOS DSLR range are Lithium-Ion (Li-ion) but not all. The NP range uses Nickel Metal Hydride (NiMH) technology. These are large, high-capacity batteries for professional cameras. The LP series, of which the LP-E6N is part, uses Li-ion technology that allows the manufacture of a lighter and higher capacity battery than the NP range.  Canon also makes the BP and NB battery ranges. The BP battery is used in consumer and semi-professional cameras. For example, the Canon XF100 camcorder uses the BP-945 and BP-970 batteries, both use Li-ion technology. The NB battery range is a smaller Li-ion battery that is used in Canon’s lightweight consumer cameras.
