I have a 2003 F150 that sits in my garage for long periods of time 3-4 months between drives. To reduce battery drainage, I just installed a Red Top Optima together with this master battery switch, made by Littelfuse. It is installed on the negative side of the post. Here's the specs:

"Works on 12-24 Volt Systems and up to 135 amps..."

Ok, I understand the Red Tops are rated fo 800 CCA's. My concern is will this master switch bottleneck the battery's 800 CCA potential whenever I start the truck?

Thanks in advance.
