I’m in the same boat. I’ll tell you what brand of rechargeable not to use, that’s “RavPower. ” I found them on Amazon, pack of 8 batteries with a charger for $20, and they’re junk! From what I’ve seen on Amazon, just about any battery that’s “Arlo approved” is really good per the comments. I mean yeah you’re going to drop $40-50 but that’s just one time. A pack of 4 CR123 disposables is $20-$30 depending on where you go.
