Rent NowProMaster USB-C Rechargeable Lithium-Ion Battery (Nikon EN-EL15c Replacement)
High-Capacity Smart Power Pack – 2,250 mAh / 15.75 Wh Output, Integrated Direct USB-C Charging Port, Dual-Color LED Status Indicator, Comprehensive Nikon Z-Mirrorless & D-Series DSLR System Compatibility (Supports Nikon Z8, Zf, Z6 III & D850), Fully Compatible with OEM External Chargers & In-Camera USB Power, Multi-Stage Electronic Circuit Protection, Includes USB Type-C to Type-C Cable & Dual-Bay Protective Storage Travel Case (Excellent Condition)
The ProMaster USB-C Rechargeable Lithium-Ion Battery is an advanced, high-performance power solution designed to replace Nikon EN-EL15c, EN-EL15b, EN-EL15a, and EN-EL15 battery packs. Engineered for professional hybrid shooters, wildlife documentarians, wedding creators, and travel photographers, this pack integrates a direct USB-C input port into its housing. This design enables fast, convenient recharging in the field using common USB-C power banks, laptop chargers, car adapters, or USB wall blocks, eliminating the need to haul proprietary external charging cradles or tie up the camera body with in-camera charging.
Constructed using high-density lithium-ion cells delivering 2,250 mAh (15.75 Wh) of energy at 7.0V, this battery reliably powers high-drain flagship cameras such as the Nikon Z8, Zf, and Z6 III through intensive 4K/8K video capture and high-speed continuous RAW shooting bursts. It provides versatile triple-mode charging flexibility: charge directly via its onboard USB-C port, inside compatible camera bodies via in-camera charging, or through traditional OEM Nikon wall chargers (such as the MH-25 / MH-25a). A built-in LED charging indicator glows red during charging and shifts to green once full replenishment is achieved (approximately 3.5 hours with a 2.2A supply). Equipped with internal circuit safeguards against overcharge, deep discharge, overcurrent, overvoltage, and short circuits, the battery includes a dual-compartment hard travel case that protects contacts from accidental metal contact while accommodating either the supplied USB-C to USB-C cable or a second spare battery.
