FCC Technician Exam Question Of The Day (T0A10)

Q) What can happen if a lead-acid storage battery is charged or discharged too quickly?

A) The battery could overheat and give off flammable gas or explode

NJ2X Notes:
It is important to treat 12-volt lead-acid batteries with respect.  They can be dangerous in spite of the apparent low voltage.  A typical car battery is capable of producing considerable current during discharge.  If charged or discharged too quickly batteries can overheat, give off hydrogen gas, or even explode.
