Well, I might have hope then, as this is not a car battery, but a leak-proof AGM battery. And it is also for a medical device. Thank you. I might call them or try to reason with them at the airport.
You still far exceed the 100 watt hours limit.

Non-Spillable Wet Batteries
Carry On Bags: Yes (Special Instructions)
Checked Bags: Yes
No more than two spare non-spillable wet batteries are allowed as long as each battery does not exceed 12 volts and 100 watt hours.

How do I determine the watt hours (Wh) rating of a battery?
A3. To determine watt hours (Wh), multiply the volts (V) by the ampere hours (Ah). Example: A 12-volt battery rated to 8 Amp hours is rated at 96 watt hours (12 x 8 = 96). For milliamp hours (mAh), divide by 1000 (to get to Ah) and then multiply by the volts.
