So do I. I'm now using low self-discharge NiMH batteries (mostly Eneloops) in pretty much every device that uses batteries, and I've never had one leak. I also use smart chargers to check battery health when I recharge them. A bit more initial outlay, but much cheaper in the long run, as the batteries can be recharged 1000s of times, and they hold their charge for many months.
