Does the 12V battery charge via the 13A charging point? 2. If not, how can i charge it seperately Incidentally the car will be on charge between 6pm and 7am each day, with a commute of about 40 miles round trip, so I am fairly sure the 13A will suffice - unless you know otherwise!

Generally, the charging current for a 12V battery is around 10% of the battery’s capacity. Charging current can vary based on battery type; lead-acid batteries are generally charged at a rate of 10% of their capacity, while lithium-ion batteries can handle higher charging currents, sometimes up to 100% of their capacity.
Charge a 12V car battery from the “main battery”. <=> Assumed here the main battery is the battery connected to the car starter engine and alternator. Use of thin cables, to not draw to much power in case “aux” battery is empty. Here is a problem, as thin cables should not be used to present a high resistance to limit the current.
As a rule of thumb, the minimum amps required to charge a 12v battery is 10% of its full capacity but the ideal charging current should be between 20-25% of the battery's capacity For example. if you have a 12v 100Ah battery then you'll need a minimum of 10 amps and a maximum of 20-25 amps to recharge your battery
For deep-cycle batteries, a general rule of thumb is to charge at 10-13% of the battery’s 20-hour capacity rating. For instance, a 100Ah deep-cycle battery would require a charging current of 10-13A. Imagine you're charging a battery, and it's kind of like filling up a water balloon.
This is why a battery charger can operate at 14-15 volts during the bulk-charge phase of the charge cycle When your battery is below 80% charged it will safely accept the higher voltage (read the spec of your battery to figure out the maximum voltage) and maximum current (Which should not be 20% of the total capacity of your battery)
My thoughts of what you will need: Charging/equalizing cables compatible with the maximum current expected to charge the Aux-12V battery. Surely anything of at least of 4 mm^2 or 12AWG, for at least 20A and a couple of meters long, but 6 mm^2 or 10AWG is good up to 30A; and 8AWG goes up to 40A safely, without overheating.

A boost DC-DC controller built with the MAX1771 DC-DC controller makes a simple switch-mode current source that is useful for battery charging. The voltage control loop is disabled so that the current control loop provides regulation.
To charge a 12V lithium battery, the required charging current (in amps) depends on the battery''s capacity (measured in amp-hours, Ah) and the desired charging speed.Here are some general guidelines: Charging Current …
1 · They typically produce alternating current (AC), which is then converted to direct current (DC) suitable for charging the battery. According to a 2021 study by Wang et al., alternators significantly impact battery charging efficiency. They ensure that batteries remain charged while powering electronic accessories in vehicles.
This mode is particularly important for applications that require direct DC power conversion, such as battery charging or DC-powered devices. The low switch losses in this …

In the following simple tutorial, we will show how to determine the suitable battery charging current as well as How to calculate the required time of battery charging in hours with a solved example of 12V, 120 Ah lead acid …
There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.
