Wall Wart = 12V 500 ma
SLA Battery = 12V 12 ah
Does anyone have a calculation I could use to figure out how long I need to charge the battery to get a full charge?
Or a close estimate?
Thanks.

What are saying that is I charge a battery for with more or less current it becomes les or more efficient. What a novel idea. AND 100% IS 12 A/HOUR THEN 18/12= 150% NOT 67% or maybe you have no idea.A 12 Ah (the "C" rate then equals 12 A) battery probably takes 18 Ah to fully charge [at constant current], so this battery would be 100*12/18 = 67% efficient.
It's easier on the battery if you take >20 hours to charge.
