What I Can Do Consumer Focus: Finding the Right Battery Instruction: Compare the prices of the three types of batteries discussed in the feature. Their comparisons should include a variety of brands and potential differences and should also account for the fact that the cost of a rechargeable battery decreases with repeated uses. If projected lifetimes of the different batteries are available, this information should also be included. Present your findings in a form of a table on a separate sheet of paper. Bases for rating: 15 points = correct answer and clearly explained the concept 10 points = correct answer but does not clearly explain the concept 5 points = tries to answer Heavy duty, "long-lasting alkaline," and "environmentally friendly rechargeable" are some of the labels that manufacturers put on batteries. But how do you know which one is the best? The answer depends on the how you will use it. Some batteries are used continuously, but others are turned off and on frequently, as in a flashlight. Still 16 others must be able to hold a charge without being used, especially if they will be used in remote control toy cars and televisions In terms of price," heavy duty" batteries typically cost the least, but they last only about 30 percent if alkaline batteries. This makes them prohibitively expensive for most uses and makes them an unnecessary source of landfill clutter. Alkaline batteries are more expensive but have longer lives, lasting up to 6 hours in continuous use and up to 18 hours in intermittent use. They hold a full charge for years, making them good for use in flashlights and similar devices. They are now less of environmental problem because manufacturers stopped using mercury in such products several years ago. However, because they are single-use batteries, they also end up in landfills very quickly. Rechargeable cells are the most expensive to purchase initially. They can cost a lot, but if recycled, they are the most economical in the long term and are the most environmentally sound choice. These cells, often called NiCads because they contain nickel (Ni) and cadmium (Cd) metals, can be recharged hundreds of times. Although NiCads last only about half as long on one charge as alkaline batteries, the electricity to recharge them costs a lot of money. NiCads lose about 1 percent of their store energyothers must be able to hold a charge Withut being used, especially if they will be used in remote control toy cars and televisions.

They can cost a lot, but if recycled, they are the most economical in the long term and are the most enviromaentally sound choice. These cells, often called NiCads because they contain nickel [Ni] and cadmiUm [Cdl metals, can be recharged hundreds of times. Although NiCads last only about half as long on one charge as alkaline batteries, the electricity to recharge them costs a lot of money. NiCads lose about 1 percent of their store energy each day if they are not used and should therefore never put in smoke detectors or ashlights. 'i.|..|F'FFI hIIJIL'i :1."
