Advice on deep cycle setup?
Hello, I have a Safari van that I've converted into a camper. I replaced the starting battery with a Duracell Ultra Dual Purpose (Starting/Cycling) Battery that cost $105 (got it at batteries ...

NOTE that the faster you draw them down, the faster squared they run down (not an exact ratio) but the capacities I gave are the C/20 rate (that is a 100 amphour battery can provide 5 amps for 20 hours before it hits zero).
If you draw current faster.. Well logically at 10 amps that 100 amp hour battery should last 10 hours. but .. in reality, due to an effect I can never rememeber the name of |(Purket?)_ it may only last 5 or six.
correct...
think puke-rt, but its spelled peukert.. the "peukert effect" works both ways.
its much more complicated than this, but in short it explains how using too small of storage capacity in relation to the load, and it will run the bank down quicker than theory would predict from the known numbers...
and yet, with an extra large bank and you will realize much more actual capacity than theory would predict, given the listed numbers.... your gains are exponential when drawing the same load from a larger bank.
this is where multiple "deep" cycle batteries can really show their full value over multi purpose batteries...
