Autozone might be able to do it. But interstate batteries definitely can do it for you. For free.

The mechanic should have a pile load, essentially an epic resistor.
Lead acid batteries are damaged going below 10.5V. Deep discharges eat away the plate material. Normally when you discharge you convert some lead to lead sulphate. But when you deep discharge it's to the point where the plates become damaged/perforated. So then when recharged the lead doesn't have a plate to cover, (IE it's not going to fill in any perforations in the plates, it'll just make the remaining sections of the plates thicker...potentially leading to internal shorts. Plus the lower internal surface area due to the damage will lead to a higher internal resistance).
Here's some info on how lead acid batteries work Battery Basics

Thanks for the knowledge but really I was asking how/where to get it load tested. It was very informative though. Thanks Jud!
Well guys I'm at it again. Just bought a double-din touch screen HU and a new sub amp. I'll be starting a new Build long soon and this one will be more SQ oriented.
