Aa batteries in parallel. The basic concept is that when connecting in parallel you add the amp hour ratings of the batteries together but the voltage remains the same. Connecting in parallel increases amp hour capacity only. Theoretically batteries connected in parallel sum up their ampere rating then if the 12 cat battery let say has 200 ah rating then 2 x 200 ah 400 ah. Therefore you need 4 x 100 ah 400 ah in parallel provided that the voltage required is 12v. Parallel connection attains higher capacity by adding up the total ampere hour ah. You can connect your load to one of the batteries and it will drain both equally.
Current is the rate at which electric charge passes through a circuit and is measured in amperes. Two 6 volt 45 ah batteries wired in parallel are capable of providing 6 volt 9 amp hours 45 ah 45 ah. Laptop batteries commonly have four 36v li ion cells in series to achieve a nominal voltage 144v and two in parallel to boost the capacity from 2400mah to 4800mah. To join batteries in parallel use a jumper wire to connect both the positive terminals and another jumper wire to connect both the negative terminals of both batteries to each other. Current isnt something you supply it is something that is drawn from a. Likes 256bits and sophiecentaur.

When the load is removed the ocv for each battery would want to be different so rapid current flow between batteries occurs to keep the voltages equal. Amazons choice for aa parallel battery holder lampvpath pack of 8 aa battery holder bundle 2pcs single aa battery holder 2pcs 2x 15v aa battery holder with leads 2pcs 3x 15v 3 aa battery holder with wire 2pcs 4x 15v 6 volt battery holder. That extra current flow you get as they self balance is not a good thing. Negative to negative and positive to positive.
You have a little misunderstanding about current. If a 15v 13 ah aa battery is used this set up would provide a voltage of 3v and a capacity of 26ah. Batteries in parallel same voltage and increased capacity. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. The four batteries in parallel will together produce the voltage of one cell but the current they supply will be four times that of a single cell. Several aa batteries in parallel will handle that current for a short while but as at russwatters said they wont last long cheers dave.
Hence when charging these batteries it is important to utilize a charger that satisfies the 12 volt capacity that is necessary for both the 6 volt batteries connected in series. The voltage under load is the same for all of the batteries in parallel of coarse but the soc of each is different.
