I'm having some problems with battery voltage dropping way too low in my morning commute to work with headlights on. I have two extra starting batteries laying around in the garage, and figured that I could just wire them in parallel with the existing battery in the Paseo. This should increase capacity, decrease peukert effect during discharge and recharge, and generally extend the life of the batteries.

The downside of this is, these batteries are all different. None are in amazing condition, and are very unbalanced as far as a battery pack goes. How is linking them all in parallel going to effect the other batteries? Are the stronger ones going to basically charge the weaker one? Is the weaker one simply going to waste this charge since it can't hold it? I'm not sure how they'll effect each other and any insight would be great.
