I don’t know about you, but I order my batteries thru eBay.
easy and cheap.
As soon as I get them I test a few for longevity.
Stay tuned….. I’ll post when the LED goes out.
The LED remained illuminated until Monday. Not as bright as I might want but still glowing.
All in all – $13 USD for 100 CR2032 batteries is a bargin!
