The MB-N10 can accept two EN-EL15c or EN-EL15b rechargeable Lithium-ion batteries, each housed in its own battery compartment. EL15a/EN-EL15 batteries can also be used in place of EN-EL15c/EN-EL15b batteries. Battery endurance (the number of pictures or length of movie footage that can be recorded on a single charge) vary with the battery. For convenience, the batteries are hot-swappable, which means that you can replace one while the other continues powering the camera. This is beneficial for video, interval and time-lapse shooting. With two batteries, power is first drawn from the battery in chamber A until it is depleted, and then the unit draws power from the battery in chamber B.

Other features include battery power level displays for each battery, a socket for connectivity to a tripod and the ability to use the optional EH-7P Charging AC Adapter to charge the EN-EL15b batteries while inserted into the unit, whether its attached to the camera or not.
