What do you refuse to get generic versions of?

Here’s a comparison site that graphs the voltage during discharge of a bunch of AA and AAA batteries with various loads using a high-end battery tester.
NiMH rechargeable AAs trounce every alkaline under heavy load. It’s not even close at 0.5A and above. Disposable lithium is better still up to 2A, but extremely expensive. Few devices will draw more than 2A from an AA battery, but I can think of a couple of flashlights that do; disposable lithium is unsuitable for those.
