I did not expect this much difference, but boy was this worth it. Bought it completely spur of the moment, and regretted it immediately afterward. Now that I have it and it is in, I am surprised to say it has made a HUGE difference. Went from the factory 540 CCA motorcraft battery to this Optima BlueTop Marine 800CCA Starting battery (not deep cycle)

I had done the big 3 with 0 gauge wiring, and still had some dimming of the headlights, which kind of bummed me out. With this, I definitely am getting better power, though I haven't checked the voltage yet. I have been unable to see any dimming, and my amp is not clipping where it once was, I assume because it is getting a higher voltage and therefore higher wattage of cleaner power.

I also love how the bluetop has some additional accessory posts, normally for marine battery chargers and such, I suppose, but it will make it easier adding small accessories now, given the heavy wire I have to the main posts. It didn't fit into the factory battery tray but should with some slight modification.

I ordered mine from advanceautoparts.com
Use coupon code VISA to get $50 off. I paid $154 shipped (and used DIFFERENT code that only got $36.40 off.

ON TO THE PICS!:

 

Nice! Just upgraded to an 85 month Interstate myself. Best part is I paid nothing.

 

not a bad deal i guess. haha

what should I sell my old battery for? I put it on CL for $30, should I ask more? I shouldn't think it's worth much used.

 

Wire it up as an accessory battery in your toolbox(if you have one). That'd be a cool mod.


How is it "better"? Just interested to know. Also I find it interesting that all noobs/infrequent posters know the term "Big three". But every poster always is posting questions about obvious **** such as body lifts.

 

More CCA and better warranty.

 

More CCA for what? Cold starts? Does it start stronger/quicker? In the cold I just plugin my truck it warms my engine and battery.

 

The fact is my lights don't dim now. which was my main goal. its keeping the voltage higher, better output from my amplifier. its basically helping the electrical system where my audio setup was taking away from that.
I had HEARD they were lighter than OEM, but at least in this case, not true. about the same.
just a bonus, as mentioned, are the accessory terminals, which can make some accessory installs easier.

oh and i do have a toolbox. so maybe. we will see.
