Newer batteries for Pro3 and newer last longer then the old ones.&nbsp;</P> Sun, 25 Apr 2021 20:06:19 GMT dcfox1 2021-04-25T20:06:19Z https://community.arlo.com/t5/Arlo-Pro-4/Arlo-Pro-4-Battery-does-not-match-older-models-purchased/m-p/1819005#M378 <P>Purchased an Arlo Pro 4 camera, and wanted to be able to simply remove the battery and use the older charger of the prior Arlo models I had purchased.&nbsp;</P><P>&nbsp;</P><P>However the battery is NOT the same, and therefore a separate charger is required.&nbsp;</P><P>&nbsp;</P><P>These should match so that older battery units and chargers are interchangeable. Seems wasteful not to have a matching unit and be able to charge the newer unit with the older charge box. (too much profit, not enough environmental impact review of products before placing on market!)&nbsp;</P> Sun, 25 Apr 2021 03:51:57 GMT https://community.arlo.com/t5/Arlo-Pro-4/Arlo-Pro-4-Battery-does-not-match-older-models-purchased/m-p/1819005#M378 Retired_Member 2021-04-25T03:51:57Z https://community.arlo.com/t5/Arlo-Pro-4/Arlo-Pro-4-Battery-does-not-match-older-models-purchased/m-p/1819087#M389 <P>The correct charger comes with the Pro4.
