In the Arlo Pro 2, one finds a 7.2V rechargeable lithium-ion Battery with capacity of 2440 mAh and 17.57 Wh energy. That model bears the name VMA4400 and here the good news, it works well with the original Arlo Pro and also with the Arlo Pro 2. So, if some own both camera versions beside each other, one can use the same batteries and the charger without any issue.
Beyond the own products of Arlo, exists a whole market with third party replacements. Companies like ZTHY, Oyomba and FGGHOO produce fitting batteries, and some of them come in a double pack with station for charge. Some better options expand the capacity to 3000 mAh, in case you want more time between charges.
Arlo Pro 2 Battery: How Long It Lasts, Charging and Replacements
Great deals exist out there, where some stores offer OEM-batteries for less than twenty dollars. Even so, matter to match the Battery to your exact model of Arlo, the Arlo Pro 2 will not match with those made for the Ultra or Pro 3, because they have totally different sizes.
Now, the life of the Battery commonly seems mysterious. I observed setups that run for weeks or even months on one single round, while others drain in amazingly fast rhythm. One common complaint is that batteries empty from full to totally dead in only four days, even in spaces with little movement inside.
More surprisingly, camera devices work without trouble during three years, but later sharply consume energy like mad. There exist even cases, where two fresh batteries, fully charged, sharply shut off before the next evening. On the other hand, some users enjoyed almost seven years of faithful service from their batteries, without real wear.
Set exactly the camera options help a lot to delay the drain of the Battery. Zones for motion alter everything, especially if street or driveway show. Intrusions can quickly drain the energy, especially when the cameras keep disconnecting and reconnecting to the base station, that continuous reconnecting drains the power quickly.
Moving the base station a bit away from the router sometimes settles the problems well.
Charging the Battery itself can be a weird cause. Those batteries do not work with each any USB-cable that lies around, they are picky about the charger. The device that comes with the camera is a Qualcomm unit with fast charge built in, designed specially for care about the higher voltage that the Arlo Pro 2 requires.
Draining the batteries fully before recharging does not always cause problems, although the experiences range.
Here a key spot: the camera does not work, even when connected to the net, if a Battery is missing, no light, no syncing, nothing. Both the Arlo Pro and Arlo Pro 2 reached end-of-life status, which means that official Arlo parts and backup batteries are not always found easily. Hencethird party options became this important for anyone that still uses this system.
