Camera Batteries & Chargers

Updated October 2026

mAh stands for milliamp-hours, and it's a measure of capacity. Higher should mean longer-lasting. Should, because some third-party batteries print numbers on the label that they don't live up to. Real-world reviews are more reliable than the label.

Brand-name or third-party?

The camera maker's own batteries cost more, but they talk to the camera properly, so the battery gauge and temperature warnings are accurate. Third-party batteries from reputable companies are usually fine and much cheaper. Some cameras show a warning with them, and the charge level might be off. We'd avoid unbranded batteries with no safety markings. A bad lithium-ion battery can swell or overheat.

Charging and care

A lot of newer cameras charge over USB-C, which means one cable for camera and phone. An external charger is still handy so you can charge one battery while shooting with another.

Carry a spare. Cold drains batteries quickly, so on a ski trip keep the spare in an inside pocket. For long-term storage, leave batteries partly charged somewhere cool and dry. Retire any battery that's swollen, damaged or gets unusually hot.

Flying

In the US, the FAA requires spare lithium-ion batteries to go in your carry-on, not your checked bag. Keep the terminal covers on or put each one in its own pouch. Airlines can have extra rules for large batteries and power banks, so check before you go.
