Rayovac Mercury Free 2032 Lithium Battery, Non-Rechargable, 3 Volt 2 Pack

I needed to replace the batteries on an electronic bike bell. I did not realize these batteries were closer to $10 for other brands. I chose the Rayovac batteries because the price was almost half as much as the others and it is a brand I know. They fit perfectly and the bell is back to it's extremely loud regular level.

I recently purchased a pack of coin batteries from Walmart, and I've been extremely impressed with how long they last. I've used them in several small devices—remotes, key fobs, and a couple of household gadgets—and they're still going strong. The price was great, the packaging was easy to open, and the batteries performed just as well as (if not better than) the name-brand versions. If you're looking for reliable coin batteries that won't die on you quickly, these are definitely worth picking up at Walmart. Highly recommended!
