Rechargeable AA 3600mWh Lithium Batteries with Charger (8-Pack) – 1.5V rechargeable cells for Blink Outdoor & high-power devices
Product description
The essentials
If you’re tired of swapping AA batteries every so often, this 8-pack of rechargeable AA lithium batteries with a charging box is aimed at high-drain gadgets where “standard” cells struggle. The idea here is straightforward: 1.5V rechargeable AA lithium cells, a built-in charger storage box, and a charge indicator that tells you what’s going on.
On paper, the headline benefits are capacity and rechargeability (the listing mentions up to 2500 cycles), plus low-discharge behaviour and a “no memory effect” claim. It’s also positioned as “high power”, so it’s meant to take on devices that are more demanding than a basic remote control.
One important limitation to keep in mind: the charger and lithium batteries are said to work only together and are not compatible with other brands. That means this is less of an “any AA charger will do” setup, and more of a system you commit to.
What’s it for (and what you’ll actually notice)
This type of rechargeable AA kit usually makes sense when you use devices often enough that battery running costs start to annoy you. Think of an outdoors security setup, a digital camera you grab on the weekend, or toys and accessories that noticeably drain cells.
A practical example: say you’ve got an AA-powered outdoor camera. Instead of waiting until the camera complains, you can pop the batteries back into the charging box when you’re topping up other essentials. The LED indicators (green flashing, green steady, and red states) are there to reduce guesswork, so you’re not charging blindly overnight without knowing whether anything’s wrong.
That said, the listing also notes some models may be unsuitable for Blink, so it’s worth checking your specific device requirements before you rely on these batteries.
Key points
The 8-pack gives you a ready supply, which helps if you rotate cells or want spares. The charging box design is designed to store batteries and charge them in one place, so it’s more “grab-and-go” than using separate storage and a charger you have to dig out.
The charging process is supported by a Type C input (the listing says a 5V 3A power supply is needed for 3H fast charging). The LED tells you when charging is active and when it’s complete, and it also warns of issues such as adapter incompatibility, cable damage, or temperature/voltage/current problems.
Where it sits in the market: this looks geared towards higher-demand AA users, not the occasional low-drain device. If your AA needs are truly sporadic, a rechargeable kit may feel like extra effort for little benefit.
Where it shines
Value for repeat use: Rechargeable AA batteries can cut down on ongoing purchases once you’re into a routine.
System-style charging: The “charger & lithium battery can only be used together” note is a mixed bag—less flexible, but potentially more predictable within this product line.
Charge status visibility: The LED behaviour (green flashing vs green steady, and different red indications) gives you a clearer picture than many basic battery chargers.
Cycle life focus: The listing mentions up to 2500 cycle life and low discharge rate, which is the kind of spec you buy for when you want something that lasts beyond a few months.
What to watch before you buy
There are a few constraints that can matter more than the specs:
- Compatibility with some devices is limited. The listing says the batteries are not compatible with smoke detectors and doorbells.
- Not all Blink models may suit. It explicitly calls out that some Blink models are unsuitable.
- No mixing brands/parts. The charger and batteries are stated to be usable together only, and not compatible with other brands.
- Charging flags issues clearly (but that may mean returns). If the LED goes red, the listing suggests contacting support to solve the problem.
And one more “depends” moment: if your device drains AAs extremely quickly, you may still end up charging more often—rechargeable helps cost-wise, but it can’t fully dodge high-power consumption.

Who it’s for (and who should skip it)
It’s a solid pick if you regularly use AA-powered, higher-drain devices and want a rechargeable setup with an included charging box and clear status lights. It suits people who are comfortable checking compatibility and treating the charger as part of the system.
It may not suit you if: - you need AA batteries for smoke detectors or doorbells - you’re not willing to check whether your exact Blink Outdoor camera model is suitable - you prefer mixing and matching batteries with different chargers/brands (this one is described as restricted) - your AA use is so rare that the “set up and charge” routine doesn’t feel worth it
Is it worth it?
Worth considering if you want rechargeable 1.5V AA lithium cells that focus on higher power devices, backed by a claimed up-to-2500 cycle life and a charging box with simple LED feedback. The biggest reason it can pay off is repeat usage: outdoor gear, cameras, and other AA-heavy gadgets are exactly where you notice the convenience.
You may want to skip it if your devices fall into the listed incompatible categories, or if you need cross-brand flexibility with chargers. In particular, if you’re buying for Blink, don’t assume every model will be suitable—double-check first.
Mini FAQ
Are these batteries compatible with other chargers?
No, the listing says the charger and lithium batteries can only be used together and are not compatible with other brands.
What do the LED lights mean?
The listing describes green flashing for charging and green steady for fully charged. Red indicates issues such as adapter incompatibility, cable damage, temperature being too high/low, and flashing red can indicate the battery can’t be charged or protection events like overcurrent/overvoltage/undervoltage.
Can they charge batteries that are at 0V?
The listing claims the charger can directly activate a refresh battery for charging even if the battery is out of power and at 0V.
Are these suitable for smoke detectors or doorbells?
The listing specifically says they are not compatible with smoke detectors & doorbells.
Are they definitely compatible with Blink Outdoor cameras?
The listing notes that “some models” may be unsuitable, so compatibility depends on your exact Blink Outdoor camera model.
