Quick Tip – Buying Coin Batteries

I went to Walgreens last weekend to buy two LR44 batteries (the ones about the size of a thick aspirin) for a cat laser toy. Looking through the wall o’ batteries I found them – at $5.29 each!

I thought that was rather excessive, so instead I looked around to find the display of cheap book lights that run on LR44s. And since it was stocking stuffer time, I found a whole endcap of such items. So for $5 I bought TWO new keychain lasers that ran on three LR44s AND came with three more spares, a total of twelve batteries for $5!

For future reference, American Science and Surpus sells 10 LR44s (AKA AG13) for $1.95, plus other coin batteries (e.g., CR2016 and CR2032).
