I agree, NiMH rechargeables are better than alkalines in almost every way. They don't leak and destroy the electronics. They can be recharged 500-1000 times, so they don't end up in a landfill after a single use. They have a really flat voltage curve. They have lower internal resistance, so can provide higher currents than alkalines. I think the only exception might be in ultra low power devices which last over a year on a single charge. But even then, I am likely to use the more expensive NiMH, because I'm so fed up with leaking alkaline batteries.

Low self-discharge NiMH can last a long time in low power devices. I've got a pair of first generation AAA Sanyo Eneloops in my bathroom scale. They've been in there for 1028 days. I have a pair in the display unit for a pair of wireless fridge/freezer thermometers. That went 395 days. I've got first generation AA Panasonic Eneloops currently at 1079 days in one of the fridge/freezer thermometer sensors and 978 days in the other. 539 days in a humidity meter. 544 days in an analog wall clock.

With a good charger (not the ones included in sets of batteries) you can also refresh them through programmed charge discharge cycles if you have batteries that aren't in great shape anymore.
