AUX battery connection

I started getting a red alert notification (with large image of the battery ) on my console to take car to workshop. After investigating the issue, i learned that the Auxillary battery was still good, however, one of the connections (positive +) had come off/loose from the base of the battery.

I've taken a few photo of the issue and was hoping someone would give me an idea how to permanently fix /sawder this without costing me $200.

Thanks in advance for the assistance.

Just replace the battery because that connector is toast. A Yuasa will cost you $68 and a generic will cost $38 to $50.

Thanks bbirdwell.
That sucks! the Canadians don't get to benefit from the same pricing as the American : ) I will look for what you've suggested
So there isn't anything that can help save this battery?
Cheers,

You could try to drill the broken led stud, tap it and put stainless steel bolt to connect it back, but if the battery is older than 3 years, all that trouble could give you couple more years of less-reliable service.

Yes, we Canadians always get screwed not only on the pricing but also on the service recalls - to say the least.

Sadly,
