Open your case and then saw and drill holes to fit a 120 mm 12 volt fan -- don't cheapen out here -- get one that blows some air.
"But there's no room inside!"
Who said anything about inside?
Get a wire screen fan guard.
Don't worry bout control or switches, when you snap the battery clamps off the fan stops. The fan will cool the unit down in a tenth the time.
Do the fan thing and you can test thirty batteries per hour if that's your wish.
Even a 1100 CCA 8-D isn't going to fall on it's ass when 500 amps is sucked out of it. A bit of common sense will reinforce the notion that at the 15 second mark the voltage isn't going down like disconnected elevator.
Bad batteries always dump volts rapidly when amperage draw is maintained. Very common is so see amps slump to 30 and volts at 4 volts and dropping.
Your 500 amp machine will work just fine. The manufacturer knows where he saved money and so he does not want to see it get very hot. Stick a fan on it and be done with it.
