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.
It matters because the actual coffee flavor is extracted from grind better at higher temperatures. I'm not a scientist but I trust those that have done the research and they say that the optimal temperature for hot water in a coffee pot is between 195-200 degrees or just a little under boiling.
