This replacement lithium battery is compatible with Action 6, Action 5 Pro, Action 4 and Action 3 sports cameras. It has a rated capacity of 2200mAh and is designed for long-duration outdoor shooting. It fits snugly into the battery compartment without loosening, jamming or poor contact. Installation and removal are quick, so you can swap batteries easily on the go.

The battery uses brand-new Grade A high-rate lithium cells and is fitted with a multi-layer protection circuit board. It offers comprehensive protection against overcharging, over-discharging, short circuits, overcurrent and overheating. It will not swell while charging and maintains stable voltage output. This prevents unexpected power cuts during video recording caused by voltage changes. It delivers consistent power for continuous 4K video, long time-lapse footage and cycling recordings.

Molded to match the original dimensions, it fits precisely into the camera slot without bulging or warping. It works well with original chargers and multi-battery charging docks at a steady charging speed, and will not cause device recognition errors. The 2200mAh high capacity greatly extends shooting time compared with low-capacity alternatives. A single battery supports extended recording during hiking, underwater filming and outdoor vlog shooting, reducing frequent battery changes.

The casing is made of high-strength flame-retardant plastic that resists abrasion and impact. It stays intact against minor bumps and drops, suitable for mountains, waters, deserts and other harsh outdoor conditions. Every unit undergoes repeated charge-discharge cycle tests with carefully controlled internal resistance for a long cycle life, retaining ample capacity after repeated recharging. It can be freely interchanged among Action 6, Action 5 Pro, Action 4 and Action 3 cameras. With spare batteries ready, it reliably meets power demands for travel, extreme sports and daily short-video production, making it an excellent backup power accessory for outdoor creators.
