I am looking at them, i had a Drag specialties in it and believe or not it lasted 6 years , it was claimed to rated at 320 cca but when I had it tested today I was showing only 260 cca
Well truth be told, I'd bet you don't have the setup to properly test the CCA and with the average test equipment used that would be a guess (which often I have found to be wrong). To truly test CCA you need to leave the battery at 0 degrees for 24hrs then test cranking current.
But if it was showing 260, it needed to go as that would bite you soon.
