February 18th is Battery Day.
Alessandro Volta, inventor of the electrical cell, was born on this day in 1745.
Electric batteries are devices consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell contains a positive terminal, or cathode, and a negative terminal, or anode. Electrolytes allow ions to move between the electrodes and terminals, which allows current to flow out of the battery to perform work. 
Today, think about all the places you use batteries. If you haven’t checked them in a year, check them today, and see if they need to be replaced. If you haven’t checked your batteries in a few years, check carefully, in case the casing has leaked battery acid.
“What do I do if battery acid has leaked?”
If there is too much corrosion, check with the battery manufacturer or throw away the whole thing. If there is a small amount, remove the battery without letting it touch your skin or get in your eyes. Wear household gloves and glasses, and turn on a vent. Neutralize the leaked alkaline. Using a Q-tip or old tooth brush sprinkled vinegar or lemon juice scrub the electrical contacts. Repeat until corrosion is gone. Let dry several hours before closing or adding new batteries. Dispose of batteries at a hazardous waste site.
“How do I dispose of old batteries?”
Alkaline batteries and carbon zinc batteries may go in the regular trash, except in California. These batteries are used in most household items from smoke alarms and flashlights to toys and holiday decorations. They range from AAA to 9 volts. If unsure check with your local disposal company’s website.
Button batteries are hazardous waste and need to be brought to a collection site, check with your local disposable company for specific information.
Lithium and lithium-ion batteries may go to a battery recycling center.
For all other batteries check with your local disposal company.
- Never mix and match different types of batteries (alkaline and acid, rechargeable and disposable) or battery brands in the same device.
- Remove batteries from devices that are being stored.
