Blinkspower AA lithium batteries 3700mAh

For a trail camera outdoors, a smoke alarm at home, or another device that draws more power, these Blinkspower AA lithium batteries are designed to provide a disposable alternative to cells you need to recharge. The pack contains four batteries rated at 1.5V and 3700mAh, with a listed operating range from -40°F to 140°F.

They are non-rechargeable, so plan on replacing them rather than topping them up.

Technical details

Each cell is an AA lithium battery rated at 1.5V and 3700mAh. The pack includes four cells, and the listing gives a shelf life of up to 20 years for storage. That long storage claim may appeal to people putting together emergency supplies, though it does not mean the batteries will last that long in a device once installed.

Blinkspower also describes the cells as resistant to cold and heat across a stated range of -40°F to 140°F, and says they use a triple safety leak-proof design. Treat that as the product’s stated design feature, not as a reason to ignore device instructions or leave old batteries installed indefinitely. One practical limit matters more than the headline capacity: these cells cannot be recharged.

What it works with

The listing names Blink cameras, outdoor trail cameras, smoke alarms, remote controls, and other regularly used home smart devices. It is positioned for higher-drain equipment, while the broad AA format may also suit everyday devices that accept this battery type. Check the device’s battery requirements before buying, the product information does not identify specific models or establish that every AA-powered device is compatible.

Compared with buying cells mainly for low-drain, occasional use, this pack makes more sense when you want lithium batteries for a device that uses more power or sits outdoors in changing temperatures. A basic AA option may be enough for a simple remote, so the extra capacity claim is less relevant if long runtime or harsh conditions are not part of your use.

Usage tips

For a camera mounted along a wooded path, the stated temperature range and focus on higher-drain devices are relevant considerations, especially when retrieving the camera often to replace batteries would be inconvenient. Install the cells according to the device’s polarity markings, and keep the four-pack stored until needed if you are buying it for emergency supplies.

Battery life still depends on device settings, use, and environment, according to the listing. Capacity alone cannot predict how long a particular camera will run, a device-specific estimate is not possible without that measurement. Avoid trying to recharge these batteries, and choose another product if reusability is a requirement.

Before you decide

Can these batteries be recharged? No. They are listed as disposable lithium batteries, and the product information explicitly says not to recharge them.

How many batteries are included? The listing describes a four-pack of AA cells.

How long can they be stored? The stated shelf life is up to 20 years. That figure refers to storage, not guaranteed runtime after installation.

When it makes sense

It suits you if you need four disposable AA lithium batteries for a listed device such as a trail camera, smoke alarm, or Blink camera, and you value the stated capacity, broad temperature range, or long storage life. Not the best choice if you want rechargeable cells, need a confirmed fit for a specific model not named in the listing, or only need a basic battery for a low-demand device. The clearest reason to choose this pack is a higher-drain or outdoor use case, for routine, light use, those features may not matter much.
