Question

Although the commercial alkaline battery was developed about 100 years after the lead-acid battery, alkaline and lead-acid batteries have some similar characteristics. What do they have in common? Both lead- acid batteries and alkaline batteries are rechargeable. The electrochemistries of both types of batteries operate in acidic media. For both batteries, individual galvanic cells can be combined to achieve higher voltages. Both battery types are used in applications requiring lightweight power sources.
