Answer :
Final answer:
Automotive batteries are not permitted for use as a power source for emergency systems, while some lead acid batteries and alkaline batteries can be suitable for such settings.
Explanation:
The type of batteries that is NOT permitted for use as a source of power for emergency systems is automotive batteries. Automotive batteries are typically lead acid type and are designed to provide the high current necessary for starting the motors of automobiles; they are not generally considered suitable for the specific and critical requirements of emergency power systems that demand reliability and longevity under various conditions.
Lead acid batteries and alkaline batteries are both known to be used for emergency power systems in different contexts. Lead acid batteries can provide high current and are rechargeable, and certain types of lead acid batteries can be designed for emergency power system suitability. Similarly, alkaline batteries can be used in some emergency power applications, though they are mainly primary, non-rechargeable batteries.
