 At this point I just buy and use [[wp>Eneloop]]s. Good quality rechargeable batteries. You can by them in kits with a charger to get stared. People say the Amazon Basics rechargeable batteries are rebadged Eneloops too.
+Eneloops are nickel-metal hydride (Ni-MH) rather than alkaline. They have a slightly lower voltage (1.2v), but maintain this longer than alkaline retain their 1.5V. I've never encountered a device that wouldn't run on them, but it can happen.
+There are black ones called pros and white regular ones. The pros keep their charge a bit longer, but can be recharged many fewer times. Regular ones are a better value for money, but you might need that longer charge for some use. When I initially researched the differences I remember it was something about one was better for using for long periods and one was better in bursts, but that didn't come up again *shrug*
