Amphours are a capacity on a lable ,amps are current they dont need a lable
Note "requires cranking current up to 1000A" its not 1000Ah ,different things mr bush
I never mentioned the capacity only current

Elton mentioned voltage and i questioned 24v when he had earlier said 12v

As mr bush mention 75Ah is considerable but also very heavy could it be two 7.5Ah batteries? those small sealed 12v batteries senn in many places but light enough to carry to a charger ? In this day and age they are swiftly becoming replaced with lithium cells of many voltages and capacities not a good idea in many cases IMHO i recently replaced my old batteries in one of my drills with lithium and imported a charging pcb that takes the danger away of charging these mini bombs up!
I think doing so stops enterprising people strapping vast 200Ah leisure batteries to their scooters and increasing the range as i would if i had to rely on a scooter ,getting it on a bus though could be amusing for passengers though easpecially if it had a couple more in a trailer i like to make REALLY sure i can get home lol

Yes, there are two 12v batteries (used to create 24v).

AH that explains it ,i thought you maybe putting 24v across a 12v battery ,it can be done with two externally by joining a + to a - and using the other ones to charge normally
If they are joined + to + and - to - its still 12v

A modern charger can make a difference such as a C tek which desulphurises and helps to regenerate a battery.
