I was going to order through Amazon since it's free 2 day shipping for me. Would any of these on this page work?
Amazon.com: 18650: Health & Personal Care
I think these are the same ones you posted but through amazon
Amazon.com: 2 Samsung INR18650-25R 18650 2500mAh 3.6v Rechargeable Flat Top Batteries (Blue/Green assorted): Health & Personal Care
Those look to be the same and some reviewers are saying that they are authentic. You would probably be okay with those. There are tons of fake batteries that they just replace the covers on out there so, i normally only buy from vendors that I know i can trust. having said that, if you read the reviews, these may be worth the chance.
Yes, based on the reviews, i would buy them.
Does your wife know?
