Both the batteries that came with the MFLB do not work anymore for some reason and I'm desperate to use my MFLB. I don't want to wait a few days for shipping. Theres an Office Depot right across the street from me that has these batteries. Just wondering if anyone has ever used these Energizer batteries http://www.officedepot.com/a/products/405541/Energizer-Rechargeable-NiMH-AA-Batteries-Pack/ Will it work? Thanks!
