I'm replacing 2 Iinterstate batteries 800cca , 1000mca reserve capacity 135. I just came from walmart and what my question is they had batt. with 690 cranking amps and about 90 amps reserve marked dc [verses mc] for about $80.00 can I use them? I don't know, I'm trying to save a buck. There for a yr/2000 150 Johnson Ocean Pro. [I might be off a couple of amps]
