the only difference is that a lead calcium battery battery can cope with up to 15v charging current i charge my sla(most of which are calcium) on 13.8v usually they will charge with a normal charger(9times out of 10 it does and it is totally safe) the only difference is they don't dry up as quickly.(as a standard battery)

What? lead-calcium? if i were you, i'd build a very low amperage, 500ma psu, then check the voltage periodically, keep it outside, and away form anything you don't want to destroy
