Compatible Nikon DSLR power

This replacement battery fits Nikon D4, D4S, D5, D500, D800, D800E, D810, D810A and D850 bodies. It replaces the original EN-EL18 and EN-EL18a packs. Photographers who need a spare or primary cell for long shoots can use it. It is not for cameras outside this list or for video rigs requiring higher-capacity packs.

Thermal behaviour and efficiency

The lithium-ion chemistry delivers 10.8 V and 3.3 Ah for 35.64 Wh of energy. Normal use in compatible bodies produces typical warmth without excessive heat. Power draw follows the camera’s own management; no extra cooling is needed. The cell does not add audible noise during operation.

Build and daily handling

The black casing measures 82.79 x 56.23 x 26.75 mm and slots directly into the camera’s battery chamber. Contacts align with the original layout for reliable communication. One unit is supplied, ready for immediate charging in the standard Nikon charger. Buyers needing multi-bay chargers or different form factors should look elsewhere.

Questions about this item

How do I insert the DS-CS-ENEL18MX into my Nikon D5 and which way do the contacts face?

Slide the battery into the D5 grip until the latch clicks; the three gold contacts on the 82.79 x 56.23 mm face must point inward toward the camera body.

When will the 3300mAh Li-ion cell need replacing and how can I tell?

Expect roughly 300 to 500 full charge cycles before capacity drops below 80 % of 35.64 Wh; the camera will report shorter run time and may show a battery-age warning.

What is the first limit I hit during continuous shooting with the 10.8 V pack?

Sustained high-current draw heats the 26.75 mm thick cell, triggering the internal thermal cut-off before the 3300 mAh rating is exhausted.
