AirTag 10-Year Extended Battery Case - Uses AA Batteries - 14x More Capacity Than CR2032 | Elevation Lab TimeCapsule | Waterproof, CR 2032 Battery Replacement

I didn’t see a lot of reviews for this product so I thought I’d give it the review it deserves.June 15, 2025:Batteries are set to expire December 2050.Expected run time, without battery replacement, is 10 years, per the description.Honestly I would be happy just to not have to replace the batteries every 6-12 months which was my selling point.Yes, the device is larger than expected if you cannot gauge it from the product photos. AA batteries are not small when you want something combined to an Apple AirTag with a waterproof housing.If you want something that will be extremely reliable, than this is it. But if you want something more discrete, they sell IPXX rated, magnetic/adhesive cases that are small.4 units for $30 is a good price for the quality of the product. The rubber seals look extremely premium. They remind me of the rubber seals we had on U.S. Navy vessels for water tight integrity on door and latches. The grooves on the lid are nice and smooth, which in turn won’t damage the gasket seal. The plastic feels and looks premium as well. There are no injection mold lines/creases. There is an injection scar on the side of each assembly. The thing you’re looking for is uniformity of the plastic. No ripples, waves, and looks and feels smooth and uniform, that’s a major sign of excellent quality. That is 5/5 Stars.I like the fact that all the screws and the allen key is in one bag. I don’t want to have to disassemble it and then reassemble it. Assembling is extremely easy and absolutely perfect. Using allen screws is ideal from an engineering perspective. You get better and balanced leverage when creating the seal on the lid. It’s easy to remove anything.Functionally and practically:I put this in my carry on luggage. I used double sided adhesive strips to permanently place it. I don’t want it rolling around. I have another in my backpack which I intend to use adhesive velcro to hide it.The overall weight and dimensions, when fully installed, is nothing noticeable. It’s like holding a standard Snicker’s bar in your hand. If you’re on the fence about it, go to the gas station and that’s what you’re buying in size, just a little thinner and less healthy.Utilization:Works exactly as normal. It does not dilute the sound when you active the speaker. Using the search function with the distance and compass in FindMy works normally without fault.I haven’t tried the waterproof function, but considering the build, material, and quality, I would have unwavering faith this would not fail either. We’re not taking this thing to Titanic level depths, but I think if this thing fell into a 10 foot pool, was placed at the bottom, it would still go to the surface and end up as a floater.Conclusion:I wished I found these a long time ago. I could have saved so much money. This is a great long term investment. If they could make a line up of different versions and sizes, it would be phenomenal.I have over a dozen AirTags for different uses and purposes. I have a lot of them for my Milwaukee Packouts and this is an incredible device for what I need. Protecting your investments is critical.There are some compromises you might need to make, but having something last potentially for a decade for $10 ($7.50 for case and $2.50 for batteries) is priceless.

The AirTags have a decent enough battery life, but if you have a need for something even longer, these should work well.The main criticism I see about this is the size and whether the case affects detection range or muffles the noise of the AirTag when you trigger the speaker from your phone. Here's what I observed:The size of this is about the same as a toy harmonica. They have to use two AA batteries (Energizer lithium are the best choice) for super long operating life. They say 10 years - based upon the capacity of the CR2032 vs the two AA batteries, this works out on paper, so we'll see. I've has a couple going now for two months and they are still going great.The clamshell that holds the AirTag has a rubber gasket and is sealed with four torx-type bolts. There is nothing on the case that can be used to help affix it to an object which is a bit disappointing. The case also does not reveal what it is either. You can assemble one of these in a minute or two, it's very easy: Pop the back off the AirTag and remove the battery. Put the AirTag on the round connector. Put in two AA batteries. Close the case and screw in the 4 bolts.A cannot attest to how well it prevents water intrusion, but it is far better than the AirTag itself. The company that makes these has been making AirTag holders and protective devices for bikes and scooters for a while, and the case is pretty tough.I can hear the AirTag quite clearly , even in the case. The sound seems to resonate pretty well. It's ever so slightly quieter than a bare AirTag. Range was surprisingly good. Sitting on a countertop, I was able to detect it with my phone's finder device from 20+ feet away (a bare AirTag would get up to 30 feet). At 20 feet, the arrow on the phone points directly at it and I had no problem using the phone to find the tag.I use these for my luggage and as a location marker for our two cars. The AirTags in our luggage work great by themselves but the batteries in them typically start to report low power once a trip is underway, which is quite annoying. These should solve that problem. For our cars, wee keep one of these hidden inside. Due to the long battery life, we can hide these quite well in an inaccessible area because we don't have to dig these out every year or two to replace the batteries.Finally, getting a multi-pack can make getting a set of these a pretty good value. The 4-pack I purchased made this quite the deal.See the attached photo to get a good idea as to the size of the item. In the photo is a closed and open case and a Toyota key fob and AirTag for size comparison.

This Apple Air Tag is perfect monitoring the location of equipment without the need to change the battery every year. I put one in a Golf Cart that is being kept in storage for us. I also put one inside a Honda side by side and our motorcycle. This comes nicely packaged with the screws that hold it together in a separate pouch. The 4 screw holes have brass inserts which is much better than just plastic. The two AA batteries fit nicely into the holder and the air tag fits well into it's holder. When I put the other half of this tag holder I heard the air tag beep showing it received power. It appears to be water tight. If you use air tags to track equipment then this holder will work well for you.
