What's your time worth? Spending hours checking your battery, load testing and voltage checking, recharging, etc. Generally automotive batteries do not recover well from deep cycling. What's your peace of mind worth? Coming out from a long work day and not being able to start up and drive home totally sucks. Or being stranded somewhere. Buy a new battery and rehearse your exit procedures, ie, quit doing stupid stuff. Drive on!
Deep Cycling of itself is not the problem, RECOVERY RATE IS.
Automotive systems regulate VOLTAGE, they will supply an UNLIMITED rate of current flow which will often result in overheating, boiling off the electrolyte, plate warping often results.
Most often a problem in RVs and MHs. Dual 6 volt deep cycle batterys that are often deeply discharged and then recharged with a very ROBUST, HIGH current alternator/VR common to the venue.
Often only takes a single outing to destroy a set of 6 volt deep cycle batterys. RV/MH workaround is to use a >400W 12 volt DC to AC inverter to power the onboard converter-charger once underway.
