You really cannot go wrong with dual 1000cca optimas... Except in the bank account. If you can afford it go for it

this is brought up almost every day. just search. I use Interstates cause i get them really cheap. **** paying 180 dollars for each optima. I paid half that for two interstates.

FWIW, I just had my 3.5 yr old set of 850 CCA batteries checked my local shop with their electronic tester. They both tested "marginal" at ~680 CCA. They didn't strongly recommend that I changed them and offered me two options. $70 for a 700 CCA or $83 for 850 CCA. Of course I wouldn't touch the 700 CCA's. Both of them were Johnson Control brand that this shop private labeled.

Especially if you had access to a plug in for your block heater I don't think I would worry about the Optima. I added a 5 amp battery maintainer to my old Mercedes diesel that I plug in when I plug in the block heater which really seemed to help things as I started off with a fully charged battery every morning. I'm going to do the same thing to 7.3.

Have fun in Canada! Travis
