I bought those cheap 300 lumens flashlights and just put them everywhere, workshop, glove compartment, backpacks. I bet I have bought 20 of them and in 3 years only one has failed - and it works if I screw the cap on just right. Since they only take 1 AA battery and it lasts a long time, they are a great bargain.
Gave one to my Mom and then she bought them for everyone she knew.
That's exactly my point. A $40 light doesn't help if it's at home and you aren't. These cheap ones last a long time and at that price, you can have one anywhere you might possibly need one.
Back to the batteries...who makes Costco's Kirklands? I've used quite a few of them and have no corrosion problems at all.
