I'm not up to speed on gen 2's but i think it should be fitted as manual states and how it was originally fitted. It sounds as though it needs a good charge from a car charger to shake it into life. I also have an optimate and they can sometimes be a bit of a pain, when trying to get a flat battery back to life. I wish you luck!
If it's broken, it's not fixed.
