2-Pack Rechargeable Battery Fit for Arlo Pro 3 Pro 4 Ultra Ultra 2

In this review the GELINTO 2-Pack Rechargeable Battery set is evaluated as a straightforward replacement option for Arlo Pro 3, Pro 4, Arlo Ultra and Ultra 2 owners who need reliable spares. The single biggest reason to buy is the practical combination of two 4800mAh Li-ion batteries plus a dual charging dock with an LED digital display, which reduces camera downtime by letting users charge two batteries at once without taking the camera offline. For someone running multiple outdoor cameras, this review finds the kit a convenient, cost-effective way to keep continuous coverage.

Key Features

• High capacity: Each GELINTO battery provides 3.85V and 4800mAh capacity to extend run times compared with lower-capacity alternatives.
• Two-pack convenience: The kit includes two batteries so a spare is ready while the other charges, minimizing security gaps.
• Dual charger dock: The included charging station powers two batteries simultaneously so you do not need to remove a camera to charge.
• LED digital display: The charger shows battery percentage in clear numeric format so you know charge status at a glance.
• Multiple charging options: The station accepts USB-C and micro USB so it works with AC adapters, power banks, car chargers, or a laptop.
• Plug-and-play replacements: Designed to fit Arlo A-4a, VMA5400 and recent Pro/Ultra cameras for a direct swap when batteries run low.

Who It's For

This kit is best for homeowners and small businesses that rely on Arlo Pro 3, Pro 4, Arlo Ultra or Ultra 2 cameras and need an easy way to keep round-the-clock protection without frequent camera downtime. It is especially useful for users with multiple cameras who can rotate spares and keep a charger accessible for fast top-ups.

It is less suitable for people who require factory-branded batteries for warranty reasons or for those with much older Arlo models that use a different battery type. If you need batteries for Arlo Pro 1 or Pro 2 models, this replacement is not the correct fit.

Pros & Cons

Pros

• Generous 4800mAh capacity offers longer run time between charges.
• Two batteries plus a dual dock reduce downtime and simplify battery rotation.
• LED digital screen on the charger makes remaining charge easy to monitor.
• USB-C and micro USB inputs add flexibility for charging sources on the go.

Cons

• Third-party replacement means it is not made by the original camera manufacturer, which may matter to some buyers.
• Package includes a USB cable but not all possible wall adapters, so an adapter may be needed for some users.
