Batteries are a blessing and a curse. When you're vegging on the couch with a remote or outdoors with your camera, they're the best invention ever.
They're not so great when they die at exactly the wrong moment and you don't have replacements. Or maybe you have replacements, but they've been sitting in a drawer for a year and they've lost a lot of juice.
Depending on how many battery-powered gadgets you have in the house, you could be going through dozens of AA and AAA batteries a year. The cost adds up.
Plus, if you recycle your batteries - which you should - the recycle center might be at an inconvenient location. Then you have dead batteries filling up your drawers between trips. In the case of 9 volt batteries, that can be very dangerous.
Back to the cost, though, there is an alternative to endlessly throwing away alkaline batteries, and that is rechargeable batteries. Obviously your smartphones, tablets and laptops already use rechargeable batteries, but is that the right move for every other gadget you own? Will it really save you money?
