Question about Camping, Backpacking & Hiking
Well, you already got the answers I wanted to suggest, but I can only add that, believe it or not, Coca Cola eats the rust and you can use it for removing battery corrosion, but only if you are sure it won't enter somewhwere where it's not supposed to be. My suggestion? If you think that trying to remove the corrosion from an old flashlight will take too much time, and it will probably be glitchy afterwards, buy a new one and regularly get the batteries out when not using it. Here is an article that talks about some of the top flashlight models on the market. You might find it useful, and beside this one, there are other ones on this topic you can use as well.

If you are using alkaline batteries, use a little white vinegar on a cloth, or q-tip and wipe the area with it. You may need to do it a few times. If the corrosion is extensive, there may be damage already done. If it is not Alkaline batteries, try using baking soda in water, instead of vinegar.
