Compatible Nikon DSLR power

This replacement lithium-ion cell fits the Nikon D50, D70, D70s and D100 models. It matches the original EN-EL3 and EN-EL3a form factor and voltage. Photographers using those cameras gain a spare or replacement power source.

Extra capacity over the original

The pack is rated at 2800 mAh and 7.4 V, delivering 20.72 Wh of energy. That exceeds the 1.8 Ah specification of the factory EN-EL3, so each charge can last longer during extended shoots. The higher capacity does not change the physical fit.

EN-EL3 interface limits

The battery communicates only through the legacy EN-EL3 contacts used by the listed Nikon bodies. It cannot report charge data to newer cameras that expect updated fuel-gauge protocols. Chargers must be the original MH-18, MH-19 or EH-5 units; USB or third-party docks are not supported.

Questions about this item

Will the 1.8 Ah Li-ion cells need replacement after a certain number of charge cycles?

Lithium-ion cells typically last several hundred full charge cycles before capacity drops noticeably; storing the pack at about half charge in a cool place extends that lifespan.

What stops the battery from delivering power during a long day of shooting with a D70?

The 7.4 V 2800 mAh pack will run until its voltage falls below the camera's cutoff point; continuous high-drain use such as repeated flash recycling reaches that limit sooner than occasional shooting.

Does the pack get hot or draw extra power when left in a D100 all day?

Li-ion chemistry generates minimal heat during normal discharge and self-discharge is very low, so the battery stays cool and does not draw parasitic current when the camera is off.
