Battery Compatibility Pro 4th, 5th, & 6th Generation

Are the batteries the same dimensional size and power output for the Arlo Pro 4th, 5th, & 6th Gen? I know Pro 4 & 5 are interchangeable, just curious about Pro 6th compatibility.

They're all the same as long as you don't try to mix in XL batteries, which are longer.

Hi @weegok

Thanks for reaching out regarding this. I found some of the compatible devices after inquiring with the team. The following are: PRO5/4/3 Ultra 3/2. I hope that helps out a bit. Let us know if you have any further questions.

Just to be clear - all standard size Pro 3/4/5 and Ultra 1/2/3 batteries can be used in the Pro 6.

XL batteries cannot be used because there is no XL housing for the Pro 6 and Ultra 3.
