Power select Nikon DSLRs with this EN-EL15a Rechargeable Lithium-Ion Battery, which serves as a spare or replacement for the one provided with the camera. It is designed to offer long life and consistent power, even when you're shooting in cold conditions, and can be charged or discharged at any time without developing memory effects. The battery is compatible with the MH-25a charger.
The Nikon D7500, D7200, D7100, D7000, D850, D810A, D810, D800E, D800, D750, D610 and D500 DSLR cameras are all compatible with this battery.
We suggest carrying three batteries with you. One in your camera, one charged spare and one as a backup. This ensures your camera won’t fail you and you’ll never miss a shot. Batteries will drain quicker if you are shooting video and if you are leaving your camera on in between shots, so it’s extra important in these circumstances to carry extra batteries with you.
If you’re taking your kit with you to a cold climate, keep your batteries close to you in your pockets rather than in your backpack. Some batteries can lose their charge in the cold climates so it’s a good idea to keep them warm.
If you’ve lost your charger, we recommend using the Nikon MH-25(AS) battery charger.
A great bag to store your accessories in is the Peak Design The Field Pouch.
