Interchangeability of Pro 3 and Pro 4 batteries

[jghere]

I see the Pro 4 batteries are 5400 mAh and the Pro 3 are 4400 mAh.  Are these batteries interchangeable (same cases) except for capacity?  If so, then either charger would work, and both batteries would work in either of those cameras.

jghere,

Both Arlo Pro 3 and Arlo Pro 4 cameras use the same rechargeable 4800 mAh battery.

The Pro 3 and 4 use the same batteries but the XL version of either uses a larger one so are not swappable unless both are XL.
