You can pretty much estimate the battery's health by observing voltage and recovery after a load. It's convenient to know what the actual load is but what you're looking for is a bounce back up in voltage.

With a good charger and a hydrometer you'll increase the longevity of any FLA battery.
FWIW, I replaced my somewhat abused truck battery a couple of years ago. It saw 10 yrs., 1 mo. of service.
