It’s 2022 and I’m still somehow running out of AA batteries – that’s why I’m now buying them in bulk online

I regularly buy a whopping 48 packs of AA batteries from Amazon because I still rely on this relatively old source of power even in 2022, when I feel more and more devices are powered by internal rechargeable batteries.

Surprisingly, the main reason for my crazy use of AA batteries is modern smart home devices, such as smart thermostats and smart door locks. I have four smart thermostats, which is definitely weird, but that’s how the climate control system in my home was set back in the day. Each smart thermostat takes four AA batteries, so 16 batteries must be replaced periodically.

And yes, some homes are wired to power the thermostats, but my house isn’t, so I have to use AA batteries.

I also have two smart door locks, each using four AA batteries. So these are another eight AA batteries that I have to keep and change every now and then.

So, for the smart home upgrade I did a few years ago, I have to constantly keep 22 AA batteries on hand, ready to replace old batteries in smart thermostats and smart door locks.

There are also the usual culprits using AA batteries, like your TV and cable box remote control – which are four AA batteries in there. There are also my Xbox consoles, each of which uses two AA batteries. And there are many other devices, such as smoke detectors and carbon monoxide sensors.

Purchasing bulky batteries for my smart home devices has been helpful to replace the batteries in these common devices, as I always have batteries on hand.

I’ve been buying bulky AA batteries for a few years now, which is the best way to go if you often change batteries in whatever device you have requires them. Specifically, I bought 48 packs of Rayovac AA batteries on Amazon for $25 because they were cheaper than Duracells, and Rayovac is still a well known and trusted brand of batteries.

Why not use rechargeable batteries?

I have discovered rechargeable AA batteries, and I still use them from time to time. However, the company that installed my smart home devices suggested not using rechargeable batteries for thermostats and door locks.

The technician said they’re presumably not providing enough power. I found that I was swapping out the rechargeable batteries more often than the regular ones.

I also need toy batteries for my daughter, but those mostly use smaller AAA batteries. For those toys, I buy 30 packs of Rayovac AAA batteries on Amazon for about $15.
