   You could measure electrolyte specific gravity if you recorded it at a   
   known full charge. I've noticed that manufacturers tweak it to balance   
   lifespan against maximum current, for example a deep discharge AGM   
   might intentionally run out of acid before the plates are fully   
   depleted. There are distinct differences among their recommendations   
   for parameters like max charging current. Trojan says 10~13% of   
   20-hour AH capacity, East Penn and many others allow 30%.

   East Penn emailed me their battery charging instructions which I don't   
   have permission to post.
