As all Amateurs use batteries in one form or another, this excellent site is
well worth book marking.

Thank you for the news!. One important lesson we electronic
experimenters should draw from these FAQ is car batteries are not a
good choice for us, their specialty is delivering huge starting
currents, but they suffer a lot if discharged almost completely, even
with small currents.

=====================================
However car batteries can be used very effectively for amateur radio
operations by using them as a peak current provider in conjunction with
a modest (current wise) PSU.
A nominal 100 W RF SSB transmitter might need say 20 Amperes in the
peaks , but (even with audio processing) ,on transmit ,the average
current will hardly exceed 8 Amperes and taking into account a 50/50
tx/rx duration ratio , such a transmitter will happily operate for long
periods with a say 60Ah car battery and a 6 Amperes power supply unit.
And the battery will have a long life. Of course ,to be close to the
transceiver the battery will have to be of the sealed variety .

a certain g7 used to charge his batteries on night-rate electricity and

and that was in the mid 90's.

Above info is possibly NOT relevant . The topic is : Running amateur
radio equipment from a CAR battery.

i was given to understand the had a collection of car batteries.

Unless the night rate were substantially less than the day rate, inherent
losses in any energy conversion proly make this strategy a wash.
At 80% of the day rate, he was proly breaking even.
