Flashlight Battery Corrosion Fix?
All of us grab that seldom used flashlight and find that it glows feebly or not at all. Are there any cures (preventative maintenance) for this. I'm trying a couple of things right now but won't know ...

Batteries need high or low Ph media to work. High or low Ph media eats things for a living. Including whatever it is contained in. An answer is lithium but it's unavailable In AAA - F cell. NiMH is better than alkaline or zinc chloride for resisting case leakage, but at the expensive of losing several tenths of a volt flashlight brightness. Can't winnemall...
Even Lithium has an "Achilles heel" so to speak.. Lithium can get rather unstable if the battery seal is damaged and oxygen gets in to the point of an extreme high temperature fire.
The answer to rechargeables not having quite as much voltage which means not as bright of a incadescent bulb.. You can get LED replacement bulbs which have a large voltage acceptance range.
HERE is a 3W 100 lumen-120 lumen LED flash light bulb I am currently testing in my Makita flashlight..
My first venture down this road was a Harbor Freight LED which worked but lacked the brightness and focus of the OEM incadescent. The HF bulb is rated for 2 cell to 6 cell flashlights. I think I got it for $6 with a 20% coupon..
The replacement LED in the link above is rated from 7V to 30V.. And let me tell you it is bright and has a nice focused spot.
