Which of the following statements about batteries is false? Lead storage batteries contain lead at the anode and lead coated with lead dioxide at the cathode. O Dry cell batteries are used in tape players and portable radios. O The alkaline dry cell battery can last longer than a nickel-cadmium battery. A battery is a group of galvanic cells connected in series. A fuel cell is a galvanic cell for which the reactants are continuously supplied.

Battery manufacturers often assess batteries in terms of their specific energy (or energy capacity). The weight capacity of a battery is defined as q 3 V/mass. Why would a battery manufacturer be interested in this quantity?

When a car is not used for 4-5 days, usually the battery is discharged. What will you do to prevent this situation to happen?
