Probably not the same type of use ,car batteries are designed to give big amps for a short period and deep cycle ones small amps for a long while .
Car batteries cannot take their volts taking down under 12.5 ish without stressing the plates whereas deep cycle ones can
I doubt grannie or kids will monitor the volts so a car battery wont enjoy the outings lol
The old trick of using high volts at low amps works for nicads but modern charges use high frequency to desulphate car batteries .
Sometimes lithium batteries go so low the protection circuit cuts in and they cannot be recharged ,plugging in their charger lots of times for 5 seconds a go trick it into charging again but it could take a few hours of doing it!
