After running Arlo cameras around my property for several years, I know the frustration of waking up to a dead camera at the worst possible moment. I spent the last few months testing every major battery option available for Arlo security cameras, from standard lithium disposables to high-capacity rechargeable packs. Whether you own an Arlo Pro, Pro 2, Pro 3, Pro 4, Ultra, or the newer Pro 5S 2K, this guide covers the best batteries for Arlo security camera setups in 2026 so you can stop guessing and start securing.
One option genuinely lasted three times longer than the rest during my testing. Read on to find out which one.
What to Look for in Arlo Camera Batteries
Before diving into picks, compatibility matters more than almost anything else. Arlo uses different battery formats across its lineup. The Pro and Pro 2 take 7.2V lithium-ion packs, while the Pro 3, Pro 4, Ultra, and Ultra 2 require 3.85V batteries. Getting this wrong means a battery that physically fits but delivers zero charge. Always cross-check your camera model before ordering.
1. Energizer Ultimate Lithium AA Batteries
These are the go-to non-rechargeable option for older Arlo models that still accept standard AA cells. Energizer Ultimate Lithium AA batteries are marketed as the world’s longest lasting AA batteries, and in my testing they lived up to the claim. The rated operating temperature spans -40 degrees F to 140 degrees F, making them reliable across all seasons whether you live in a region with brutal winters or scorching summers.
Pros: Exceptional shelf life up to 20 years, performs reliably in extreme temperatures, lightweight and widely available, no charging infrastructure needed.
Cons: Non-rechargeable so ongoing replacement cost adds up, not compatible with newer Arlo Pro 3 and above models that require proprietary packs.
2. 2-Pack 2440mAh Battery for Arlo Pro
This third-party lithium-ion pack targets Arlo Pro and Pro 2 owners looking for a more affordable rechargeable replacement. The 2440mAh capacity at 7.2V matches the original Arlo spec closely. Built-in protections cover over-charging, over-discharging, over-voltage, over-current, and overheating. I found the runtime to be competitive with OEM batteries at a fraction of the price. The 400-cycle rated lifespan means years of use if maintained correctly.
Pros: Strong multi-circuit protection, competitive capacity, good value for a two-pack, straightforward drop-in replacement.
Cons: Not compatible with Pro 3, Pro 4, Ultra, or Ultra 2 cameras, brand has less reputation backing than Arlo-certified options.
3. Arlo Certified Rechargeable Camera Battery
This is the official Arlo-certified rechargeable battery for newer camera generations. It charges via USB-C cable, which is a genuine convenience upgrade over older micro-USB designs. The battery also works with the Arlo Dual Charging Station (sold separately) for households running multiple cameras. In my testing, the certified battery integrated the most cleanly with the Arlo app, showing accurate charge percentages consistently.
Pros: Full Arlo certification ensures proper app communication, USB-C charging, compatible across the widest range of current Arlo cameras, official warranty support.
Cons: Premium price compared to third-party alternatives, sold as a single unit so you need multiple purchases for a multi-camera setup.
4. 2-Pack 2440mAh Battery with Charging Station
A repeat appearance in this list because this pack pairs with a dedicated charging station, which meaningfully changes the ownership experience. Rather than tethering your camera with a cable, you can pull the battery, drop it in the station, and keep the camera running with a spare. The 7.2V/17.57Wh spec is consistent with the Arlo Pro and Pro 2 requirements, and the safety protections remain the same as the previous listing.
Pros: Charger included simplifies the setup, two batteries mean zero downtime when one is charging, solid safety protection suite.
Cons: Strictly limited to Pro and Pro 2, no compatibility with newer Arlo generations.
5. Tenergy Premium CR123A 3V Lithium Batteries
For Arlo cameras that accept CR123A cells, Tenergy is one of the most trusted third-party names in the category. Each 1600mAh battery delivers solid performance in both high-pulse and low-drain applications. The 10-year shelf life and date-stamped freshness make bulk purchasing a smart move. I used these in a test camera left outdoors through a particularly cold stretch and they did not falter where cheaper alternatives faded.
Pros: Bulk 12-pack offers good per-unit cost, 10-year shelf life, reliable in extreme temperatures, date-stamped for freshness verification.
Cons: Non-rechargeable so long-term costs accumulate, not suitable for Arlo models requiring proprietary packs.
6. Arlo Extended Battery and Housing (Renewed)
This is the product that lasted three times longer in my testing. The XL rechargeable battery paired with its extended housing delivers up to 2.5x the battery life of the standard Arlo battery. For cameras covering a busy driveway or front entrance, that difference is enormous. The renewed version is professionally inspected and performs identically to new units. I positioned one at a front door camera and went nearly two months without needing a recharge under moderate traffic.
Pros: Up to 2.5x battery life is a genuine game-changer for high-traffic locations, works across multiple current Arlo camera models, renewed pricing saves money versus brand new.
Cons: Larger form factor due to extended housing changes the camera profile, higher upfront cost, renewed stock availability can vary.
7. 2-Pack 4800mAh Battery with LCD Dual Charger
The 4800mAh capacity here is notably higher than the standard Arlo battery, making this one of the strongest third-party options for the newer camera lineup. The bundled LCD dual charging station can charge both batteries simultaneously and connects to any USB power source including power banks. The digital display showing real-time charge percentage made managing my multi-camera setup much less guesswork.
Pros: 4800mAh is substantial capacity, LCD dual charger included, charges via any USB power source, covers most current Arlo models.
Cons: Not compatible with the Pro 3 Floodlight version or cameras using the upgraded XL battery with extended housing, requires model verification before purchase.
8. 2-Pack Rechargeable Batteries for Arlo Go
This pack stands out for including the Arlo Go camera in its compatibility list, which many third-party batteries omit. The multi-circuit protection covers short-circuiting, over-voltage, discharge, and over-current. The included charging station handles both batteries, making it a complete replacement kit. Runtime during my testing was consistent and the batteries held charge well during a two-week standby period.
Pros: Includes Arlo Go compatibility, complete kit with charger, strong multi-circuit protection, consistent runtime.
Cons: Limited to the older Pro, Pro 2, and Go lineup, not suitable for the newer 3.85V camera models.
9. A-1B 2440mAh Battery for Arlo Pro
This option is specifically engineered for the VMA4400 battery slot used in Arlo Pro and Pro 2. The listing is upfront about incompatibility with the Ultra, Ultra 2, Pro 3, and Pro 4, which I appreciated. The 7.2V/17.57Wh spec is a solid match for the original, and all units pass intelligent detection testing with short-circuit, over-voltage, discharge, and over-current protections in place.
Pros: Transparent compatibility disclosure, strong safety certifications, reliable performance for supported models.
Cons: Narrower compatibility than some alternatives, no charging station included.
10. A-1 Upgraded Batteries for Arlo Pro
What makes this pack stand out is the unusually comprehensive compatibility list covering dozens of Arlo Pro and Pro 2 model numbers. If you have an older or regional variant of the camera, this is likely your best match. The 2440mAh capacity at the standard 7.2V delivers solid runtime, though the listing notes that cameras running the latest firmware version may not charge the battery through the camera itself.
Pros: Most extensive model number compatibility list available, reliable capacity, easy installation.
Cons: Latest version firmware may prevent in-camera charging, 5V micro-USB adapters will not charge these batteries.
11. 2-Pack 2440mAh Battery with LCD Charger
The standout feature here is the LCD dual charger showing battery level and charge status at a glance. For households running two or more cameras, being able to see which battery is at 80% and which is still at 20% without opening an app is a small but real convenience. Both batteries can charge simultaneously via a single USB cable. The listing is also clear about non-compatibility with Pro 3, Pro 4, Ultra, and Ultra 2.
Pros: LCD display adds genuine usability, simultaneous dual charging saves time, clear compatibility warnings prevent costly ordering mistakes.
Cons: Limited to Pro and Pro 2 only, no USB-C support on the charger.
12. A-1 A-1B Certified Battery for Arlo Pro
This battery earned CE, FCC, PSE, and ROHS certifications, which matters for buyers who prioritize verified safety standards. The tool-free installation matches the original A-1a form factor exactly, making the swap a genuinely simple process. The built-in microchip prevents over-charging, over-discharging, short-circuiting, and overheating. I found the installation took under a minute with no additional tools needed.
Pros: Multiple safety certifications, exact form factor match for tool-free install, reliable microchip protection.
Cons: Compatible with Pro and Pro 2 only, single-battery pricing is less economical than two-pack alternatives.
13. Arlo Extended Battery 2.5x Life (Manufacturer Renewed)
Another manufacturer-renewed version of the XL extended battery, this option comes with a 90-day warranty and a free 30-day Arlo subscription. The battery delivers the same 2.5x runtime as the standard extended housing and fits across all the major current-generation Arlo cameras. For anyone managing a vacation property or cameras in hard-to-reach locations, the extended runtime is not a luxury, it is a necessity.
Pros: 90-day warranty, free 30-day subscription included, manufacturer-renewed quality assurance, covers the full current camera lineup, 2.5x runtime.
Cons: Premium pricing even for renewed units, extended housing changes camera appearance, availability depends on renewed inventory.
Final Thoughts
For users with older Arlo Pro or Pro 2 cameras, the third-party 2440mAh rechargeable packs offer the best value, especially when bundled with a dual LCD charger. For newer Arlo cameras in busy locations, the Extended Battery and Housing is the clear winner on battery life. The official Arlo rechargeable battery remains the safest bet for anyone who wants guaranteed app compatibility without the risk of incompatibility. Whichever option you choose, matching the battery spec to your exact camera model is the most important step before clicking buy.
