Converter manufacturers often state that their converter/charger will charge the first 90% in 3-4 hours but then kind of quietly point out that the last 10% can take "a lot longer". This also assumes that there isn't a ton of voltage drop between battery and Converter that causes converter to switch to a lower charge rate as it "sees" a higher voltage on it's end than is actually present a the battery.

Thanks guys, much appreciated. I am definitely disconnecting before reading the meter but I have not been letting it sit much more than 24 hours plugged into the house. Would it be best to have a trickle charger plugged into the battery rather than using shore power?

Ditto that ...the SPEC on the MTI Saf T Alert 30 series detectors is .09amps for current models. Even at .2 amps that is roughly 4-5 amp hours /day which won't drain a charged battery to flat in less than a week.

No. You have a modern charger. Fully charging overnite then disconnecting the battery and letting it self discharge till it gets down around 12.2V (50%) which will take SEVERAL months will than allow you to recharge in bulk mode which will thoroughly mix the acid and water preventing stratification and sulphation. This is best.
If you leave you batts connected...then you will need to plug in every week to achieve the same effect since parasitic loads will drain the batts much more quickly. If it is too much trouble to plug in every week, then a trickle charger is the best solution.
