4pc Panasonic AA Batteries Super Heavy Duty Power Carbon Zinc Double A Battery 1.5v

I recently purchased a clock online without realizing until I received it, that it specifically requires carbon zinc batteries, which I previously never heard of and didn't even know existed. After a fruitless online search of the big box home improvement stores, I searched Walmart online and found them instantly. I placed an order for this four pack of Panasonic AA carbon batteries, and they arrived a few days later. The package opened easily, and in under a minute I had them installed in the aforementioned clock, and thankfully now it works as intended. Fast and inexpensive fix for an unexpected problem!
