ProMaster Professional Camera Batteries
ProMaster batteries are engineered to be a superior, long-lasting power solution for your camera. While many third-party batteries cut corners to lower costs, ProMaster prioritizes reliability and performance, ensuring your gear stays powered when the shot of a lifetime presents itself. Here is why ProMaster is the trusted choice for photographers worldwide:

Superior Engineering & Performance
Premium Grade Cells: Battery components vary wildly in quality. ProMaster uses only the highest-grade cells available to ensure a long service life and consistent power delivery. We refuse to use sub-par components, choosing instead to build a battery you can depend on.

Honest Capacity Specs: Many brands overstate their battery capacity by as much as 20%. ProMaster provides verified, honest specifications. Our stated capacities are optimized through precise engineering and confirmed through rigorous quality control testing.

True System Compatibility: Unlike “partially decoded” third-party batteries that trigger errors after firmware updates, ProMaster batteries feature fully decoded chips. They are guaranteed to work seamlessly with your camera, the original manufacturer’s charger, and in-camera charging systems.

Safety & Protection
Advanced Circuitry: Every battery features fire-retardant PCBs and a comprehensive protection suite, including overcharge/discharge protection, overcurrent and overvoltage regulation, and short-circuit prevention.

Protective Storage Case: We’ve eliminated wasteful throw-away packaging. ProMaster batteries come in a durable, reusable hard case. This keeps your battery clean and prevents the contacts from touching metal objects or sustaining damage during transport.

A Heritage of Trust
60+ Years of Excellence: ProMaster has been a staple in the photographic industry for over six decades—longer than many camera brands have existed. You can find our products in the world’s finest independent photo and video specialty stores across the US, UK, Canada, Costa Rica, and Australia.

No-Hassle One-Year Warranty: We stand behind our workmanship. All ProMaster batteries are guaranteed for one full year. In the unlikely event of a defect, your battery will be exchanged at no charge at any authorized dealer.
