At our shop, all of our race cars have used standard batteries. They always start when you need them to, and aren’t as susceptible to odd voltage glitches that the car may not like. (Been there, chased that).
This is in a Volvo, no? Do you know if your car has a more intelligent charging system than just your basic voltage regulator?
For the cars I see, all the new stuff goes to charging regulated by the engine computer or a power module. These are cars where it changes the algorithm it uses to determine charging voltage/amperage based on many factors, including type of battery/size/age.
Not trying to diss your new setup! Sounds like a wild battery, and a weight difference you can feel!
Last thing as a guy that does tech inspections for track cars - you might want to look at adding some plastic in front of the battery to insulate between the positive terminal and the body. In a perfect world, it shouldn’t make contact, but... (SOP for tech inspections dictates at a minimum that the positive terminal is covered)
