What Type of Batteries Do Cameras Use? A Complete Guide

From vintage film cameras to modern mirrorless systems, batteries are the unsung heroes that keep photographers shooting. But with so many camera types and brands, it’s easy to get lost in the maze of battery options. Whether you’re a film enthusiast, a DSLR loyalist, or a mirrorless adventurer, this guide breaks down the batteries your camera needs—and why manufacturers love keeping you on your toes with proprietary models.

Film Cameras: Compact Power with Button Cells

Before the digital era, film cameras relied on compact, long-lasting button cells. These tiny batteries powered light meters, automatic film advance mechanisms, and flashes in classic point-and-shoot and rangefinder models.

Common Battery Types:

• LR44/SR44: The most widely used button cells, often found in cameras like the Olympus Trip 35 or Canonet QL17 GIII. LR44 (alkaline) are affordable but drain faster, while SR44 (silver oxide) offer stable voltage and longer life.

• CR123A: Used in some advanced film cameras with built-in flashes, like the Nikon L35AF.

Why Button Cells?
Film cameras require minimal power compared to digital systems. Button cells are small, lightweight, and perfect for low-drain devices. However, they’re not rechargeable, so always carry spares for long shoots.

Pro Tip: Replace silver oxide batteries every 6–12 months, even if unused, to avoid leakage damaging your vintage gear.

Digital Cameras (CCD Era): The Versatility of AA Batteries

Early digital cameras, especially CCD-based compacts, often used AA batteries for their simplicity and universal availability. Brands like Nikon (Coolpix) and Canon (PowerShot) embraced this approach, appealing to travelers who could swap in alkaline AAs from any store.

While AA batteries offer convenience, they limit camera design due to their size. Modern digital cameras have largely moved to proprietary batteries for slimmer builds.

Did You Know? Some rugged cameras, like the Olympus Tough TG-6, still use AAs for their accessibility in remote locations.

DSLR Cameras: High-Performance Proprietary Packs

DSLRs demand robust power for mirrors, shutters, and advanced autofocus systems. This led brands to develop proprietary rechargeable lithium-ion packs tailored to their cameras’ needs.

Popular DSLR Battery Models:

• Canon LP-E6: Powers the EOS 5D Mark IV and 7D series. Known for reliable 1800mAh capacity.

• Nikon EN-EL15: Used in the D750 and D500, with variants offering up to 1900mAh.

• Sony NP-FW50: Found in older Alpha DSLRs like the A77 II.

Advantages of Proprietary Batteries:

• Higher Voltage Stability: Ensures consistent performance during bursts or video recording.

• Compact Design: Fits seamlessly into camera grips.

• Smart Chips: Track battery health and usage.

Third-Party Options: Brands like K&F CONCEPT offer affordable alternatives, but check compatibility—some cameras (e.g., Canon) may block non-OEM batteries via firmware.

Mirrorless Cameras: Efficient Power in Smaller Packages

Mirrorless cameras ditched the optical viewfinder to save space, but their always-on electronic viewfinders and 4K video demand efficient power management. Modern mirrorless systems use advanced lithium-ion packs with USB-C charging for versatility.

Popular Mirrorless Battery Models:

• Sony NP-FZ100: Powers the Alpha 7 IV and A1, offering 2280mAh for extended shoots.

• Canon LP-E6NH: Used in the EOS R5, supporting faster USB-PD charging.

• Panasonic DMW-BLK22: Designed for the Lumix S5 II, optimized for video-centric workflows.

Why Proprietary Dominates?
Custom batteries let brands balance capacity, size, and camera performance. For example, Fujifilm’s NP-W235 (X-T5) is engineered for rapid charge cycles.

Maximizing Battery Life:

• Enable airplane mode to reduce Wi-Fi/Bluetooth drain.

• Use USB-C power banks for continuous shooting.

The Future of Camera Batteries: Universal vs. Proprietary

While AA and button cells still have niche uses, the shift to proprietary batteries reflects brands’ push for ecosystem loyalty. Critics argue this creates e-waste and limits user flexibility, but innovations like USB-C charging and power-delivery support are steps toward convenience.

Key Takeaways:

1. Film Cameras: Button cells (LR44/SR44) for simplicity.

2. Early Digital: AA batteries for accessibility.

3. DSLR/Mirrorless: Proprietary lithium-ion for performance.

Final Tip: Always check your camera’s manual for approved batteries, and invest in a quality charger to prolong battery health.
