James,
If you like to target shoot to keep your skill level up like me and have red dot scopes then you know how expensive those coin or “button” batteries are. I have been looking for a rechargeable coin battery for a while. Well I found it. There are now CR-2032 LI-ION rechargeable batteries. For $1.75 each (if you buy 10 or more), I think its a deal. The recharger is only $5.75.
I hope this will help those who enjoy plinking and are looking to save a few dollars. Service was great and fast shipment. Disclosure: I have no connection to this company. – Jeff B.
JWR Replies: As was pointed out by reader Karl A.: The CR-2032 LI-ION battery is NOT a direct replacement for the CR-2032! It’s voltage is twice that of the standard CR-2032. You might fry your very expensive red dot sight trying it as a direct replacement. If you have a device that needs two CR-2032 batteries, then you might be able to use a conductive spacer made from a dead battery, along with one of the new Lithium Ion batteries.
