It's a sad day when the best battery reviews are found buried in an Amazon rating, but there is someone who actually went ahead and tested batteries but:
- AAA Alkaline. AC Delco. the no-name AC Delco came up on top and for less than the cost of Amazon Basics even?
- AA Alkaline. Duracell Quantum. Then there are AA batteries where BatteryNinja and Consumer Reports says the Duracell Quantum AA are the longest lasting, although the Costco ones are half the price and a good value.
- AA NiMh rechargeable. Everready. Finally if you want rechargeable, it looks like the Eveready has the best ones according to Wirecutter.
