Better batteries, or alternatives to them entirely

   The humble battery. Simultaneously one of the most frustrating and overlooked requirements for our new mobile society. Frustrating because there’s few things more annoying than unexpectedly running out of juice on your latest electronic gadget. Overlooked because they sit and wait patiently until they are needed and then they are expected to perform at their peak.
   Today’s sustainable topic looks at ways to transform this device from a symbol of our insatiable thirst for energy and cavalier throw-away lifestyle into a more environmentally friendly commitment to preservation.
   Batteries of course come in all shapes and sizes. Some of the better known sizes include small batteries for watches or medical devices, the familiar AAA through D sizes used in most electronics and toys, and the larger sizes used for cars, trucks and other forms of transportation. Even within each size, you have different chemical types (alkaline, NiMH, NiCd, Lead Acid, etc.) and different ratings (Heavy Duty, Super Heavy Duty, quick charging, etc.). Many of the ratings are simple marketing terms that have no real standards so do not put too much emphasis on them. In fact, it may be better to bypass the batteries all together and see what you can do without them.
   The best way to “quit the juice” is to participate in activities that don’t require mobile electricity, or purchase items that do not require a battery. Here are eight ways to cut down on the batteries you use:
   • Take a walk with your friend or your family, instead of listening to music. Not only will you have something interesting to listen to (and talk about), you are more likely to stick to a routine if you have someone with you.
   • Board games and card games are also excellent sources of recreation that require no batteries. Kids often get more enjoyment from spending time with their parents than owning the latest “must have” electronic toy.
   • Building toys, such as legos, blocks, tinker toys, Lincoln logs, even puzzles are excellent ways to keep kids busy and battery free. It also fosters an attitude of building up society instead of the many video games, which concentrate on creating chaos.
   • Books that are age appropriate and related to a kids (or adults) interests are probably the best way to stimulate the imagination and create peaceful time. A book read to young children before bedtime is still the best way to get kids interested in reading at an early age.
   • Another good way to stimulate creativity is through art supplies such as colored pencils, crayons and markers. As children age, they can experiment with other media such as paints, pastels, and charcoals. Creating art projects is also a great way for seniors to stay creative and active.
   • Sports equipment and a place to play are unequaled in giving kids hours of time to play and keeping them physically fit. Getting together with other families not only allows kids to play with their friends, but it also gives parents a chance to share adult conversation with others.
   • If you are purchasing electronics, look for some that have alternative methods for generating electricity. A few flashlights have come on the market that can be either shaken or cranked for electric power. Slowly, other devices are also being adapted to battery free functionality.
   • If you must have a device that requires batteries, look to see if it can use rechargeable batteries. The myth that rechargeables don’t last as long as alkaline batteries is long since dead. Many of the current NiMH batteries will last as long as or longer than standard batteries. In fact, to make the rechargeable batteries last longer, put them in your refrigerator or freezer. NiMH batteries kept at room temperature will loose their charge at a few percent per day, whereas those kept in the freezer will retain 90 percent of their charge for a month. Be sure to let the batteries warm to room temperature before using.
   Batteries do have their place, like in cars and medical devices and some of the electronics we rely on daily. Whenever possible, recycle the car batteries when purchasing a new one. You can also check out your local retailers, like Staples or Radio Shack or some hardware stores, to see what types of batteries they will recycle for you.
