The AmazonBasics rechargeables are also quite good in my experience, both the "regular" glossy black-labeled ones and the "premium" white-labeled ones (the matte black "high capacity" ones are, I'm sure, also fine, but probably overkill for mice and keyboards). The white AAs are likely rebranded second-generation Eneloops, whereas I don't think we really know much about the glossy black ones (of course, this is also a guess for the white ones, but a highly educated one based on the electrical characteristics and physical features of the batteries). The glossy black ones are cheaper and I've only had a few "duds" (they all still work to some extent but one or two of the dozen I have started losing their charge quickly), whereas I've had no problems at all with the white ones, but if it's just a peripheral it might not matter too much.
Of course, actual Eneloops are also highly regarded, as the above poster mentioned. But you may be able to save a bit by going with a rebranding if that's important to you.
