Good advice apart from the capacity check. As you say and have proven for yourself "deep discharge really kills a battery". There are dedicated thick plate deep discharge or traction batteries which fair far better under such regimes. With a starter battery, as a minimum, a full discharge takes a chunk out of its service life.
