    Odysseys are nice. They are just about the only ones who make a thin plate cranking battery that is also rated for deep cycle use.

    Note in the specs on the PC1500 that it can handle 400 cycles...

    The answer is: All parameters.

    If the battery lists CA, CCA and RC, then it's pretty much guaranteed to be a cranking battery. A deep cycle battery will list Amp*Hours (AH) instead. Cranking batteries have lots of thin lead plates...

    They told you wrong.

    The alternator is supplying current to the exact same place that the secondary would be pulling power from - the positive terminal on the primary battery. So the current will...

    How much current any given wire can carry depends on A) the wire type (copper, aluminum, tinned, bare, stranded, etc.), B) the insulation's temperature rating, and C) how you use it.

    400w / 12v = 33.3a

    Dunno what its surge rating is, but if you don't go over 400w on it, #8 would be fine.


    With a 20a fuse, then you would be limited to:

    20a x 12v = 240w

    So, if you draw...

    Dunno what that plastic is, but it's probably not heat rated. Most wire insulation is rated 60C, 75C and 90C, so if it can handle that, it should be fine. If you are overheating the wire beyond its...

    That's a misconception.

    All lead-acid battery lifespans are rated in cycles. The lower you drain them, the less cycles you get. You might get 3000 cycles if you only drain them 50%, and might only...

    From the manual in the OP's link, that BM is a 2-stage: bulk to 14.2v then drop to float at 13.4v. It'll get the job done, but a 3-stage that does an absorb stage would be better.
