Hi
The simple answer is to connect the second battery in parallel with the first. It will effectively increase the ampere-hour capacity and lengthen the time before it runs out. Having said that, if your main battery is in good health and you are only draining a couple of amps to run the ignition, it will do that for many hours running.
May I make a plea for all batteries to be clamped or strapped down securely. You don't want them moving around and short circuiting if the worst happens.
