Frequently Asked Questions
Can I use CR123A or CR2 batteries in my mirrorless camera?
Most mirrorless camera bodies use proprietary rechargeable packs, not CR123A or CR2. CR123A and CR2 are commonly used for flashes, triggers, LED lights and other accessories. Always check your device’s manual before installing non-camera cells.
Are third-party batteries safe and reliable?
Many reputable third-party brands offer safe, reliable cells and chargers, but quality varies. Look for PTC protection, buy from known sellers, and avoid mixing old and new cells. For critical shoots, keep OEM spares or proven third-party cells you’ve tested.
What’s the best way to carry spare batteries and a charger when traveling?
Use a small hard case with separate slots to prevent shorting and mechanical damage. Choose a compact dual charger or rely on in-camera charging if supported. Keep spare cells in original packaging or insulated holders, and follow airline rules for lithium batteries when flying.
