Main > Technology > Useful things > Batteries Extending the use of alkaline batteries: If your alkaline batteries no longer hold enough charge to power a high-current device, such as a digital camera, they will probably continue to work in a low current device, such as a digital clock or a remote control. This will give you possibly another 6 months of use out of your batteries.   Kevin Solway (173)

Main > Technology > Useful things > Batteries Cheap vs Expensive rechargeable batteries: Cheap rechargeable batteries (e.g., cheap NiMh batteries) will not hold their charge for very long, even if you don't use them. More expensive rechargeable batteries, such as "Eneloop" batteries, will hold their charge for a great many times longer. Lithium-ion batteries tend to hold charge for a longer period than NiMh, when not in use.   Kevin Solway (173)

Main > Technology > Useful things > Gadgets > Fire-starters To start a fire: Locate a sheltered spot, a dry non-flammable bed like sand, air inflow pressure preferably beneath the fire, dry kindling, and a fire-lighter (matches, cigarette lighter, or flint).   kellyjones00 (593)

Main > Technology > Useful things > Gadgets > Fire-starters If dry, these can be used as kindling: citrus peels, chaff, husks and nut shells, twigs, paper, wood shavings, bark, bits of wood dipped in leftover candle-wax.   kellyjones00 (593)
