Rechargeable Battery Pack for Arlo Pro 5S 2K Pro 4 Pro 3 Ultra 2

In this review the focus is on a practical replacement battery kit for Arlo cameras: a 2-pack of 4800mAh rechargeable lithium-ion batteries with a dual slot LCD charger. The bottom line: this kit is for owners of Arlo Pro 5S 2K, Pro 4, Pro 3, Ultra 2, or Ultra cameras who need longer runtime and convenient charging for spare batteries. The reviewer found the higher capacity cells, broad USB charging options and the clear LCD readout to be the most compelling reasons to replace factory batteries or keep ready spares.

Key Features

• Higher capacity cells: 4800mAh lithium-ion batteries provide longer recording windows compared with standard packs, helping capture more events before recharge is needed.
• Wide compatibility: Designed specifically as a replacement for Arlo Pro 5S 2K, Pro 4, Pro 3, Ultra 2 and Ultra cameras, which simplifies finding a correct aftermarket option.
• Dual-slot LCD charger: The included 2-channel charger charges two batteries at once and the LCD clearly shows each battery's remaining capacity so users can judge readiness at a glance.
• Dual charging inputs: The charger accepts both Micro-USB and Type-C 5V input, allowing use with wall adapters, power banks, laptops or car chargers for flexible charging locations.
• Safety certifications: The batteries are stated to meet CE, FCC, PSE and ROHS checks, which reduces some risk compared with unknown generic cells.
• Accessory bundle: Kit includes two replacement batteries, the dual fast charger, one USB cable and an instruction manual, plus a 30-day refund and 12-month warranty for support.

Who It's For

This kit suits DIY camera owners who already use one of the listed Arlo models and want extra runtime or hot-swap spares to avoid downtime during charging. The LCD charger and USB charging options make it a good match for users who travel with equipment or maintain cameras in locations without easy AC access.

It is not for owners of the Arlo Pro 3 Floodlight model or Arlo cameras that use the larger XL battery with extended housing; those models require a different form factor. Buyers should confirm the battery size in their camera before purchasing to ensure mechanical compatibility.

Pros & Cons

• Universal Micro-USB and Type-C input enables charging from many 5V sources.

Cons

• Not compatible with Pro 3 Floodlight or cameras that require the XL extended housing battery, so size verification is required.
