Household batteries (the usual suspects: AA, AAA, C, D, 9-volt) can be recycled through battery retailers like Batteries Plus. While you save up enough old batteries to make it worth a disposal trip, keep your dead batteries in a dry place that's out of reach of kids.
Water temperature is vital. Doing it correctly, you can make what many say is the perfect cup of coffee. Ideally, you want the temperature between 195 and 200 degrees F. One way to do this is to boil the water and use an âinstant readâ thermometer from any kitchen store.
TEMP: Water heated to 195-205ÂºF is ideal for preparing coffee, and some espresso machines allow you to control this temperature. (For most systems, this is made possible by a PID controller.) If yours does, play within this range to find what you like.
