: I'm adding dual batteries to my '94 K1500. I just ordered the left-hand side Battery tray(for diesel Subs) from the dealer ($37). The plan is to use the second battery for the video setup and the interior lights so they can run down the aux battery instead of the main battery when the engine is off. I have three questions:
: 2. Should I use a deep-discharge battery? Any disadvantages to using one?
The lifespan of a deep cycle battery will be much longer than that of a conventional battery, given your application.
: 3. Also, if I run down the aux battery and then start the engine, the aux battery will require a high charge rate. Will this cause the main battery (which may be fully charged) to overcharge?
Nope. Both batteries will be brought to the regulated voltage.
