If 55 amp converter, how long to charge 76ah batteries?

I am wondering how long my house batteries should take to charge if all the components of the system are in good working order. Am I wrong in thinking it should take about an hour to fully charge the batteries if they are at 50% (38ah) charge? Is there an normal inefficiency in a good working system so that it takes longer? I had heard that flooded batteries (which I have) are less efficient in charging and could take three times as long....even if everything in the charging system is working as it should.

50% to 100% charge , on deep cycle batteries , depending on the number of batteries in the system , could take 12>24 hrs. This is according to my experience . Fact sheets may state some thing different .

Edit; I'll try posting a link to the 12v side of life, reading it may answer your question.

Biggest thing to remember is a 55 amp converter/charger is not the same as an automotive 55amp battery charger, and you wouldn't want to charge a deep cycle battery too fast any way; to much heat.

6-8 hours. if it is a top end 3-stage converter, if it is a single stage all bets are off (They either boil the batteries dry or never fully charge them).

Also 55 amps is a bit much for a 76 amp hour battery, add a 2nd battery, this will add like 10 minutes to the recharge time if that. 55 amp converter is proper for 150 amp hours of battery. (Actually a bit more than that but 150 with a few amps for lights and such works for me)

You might consider going a pair of six volt Golf Car batteries (230) They can take a 70 amp charge.

At the bottom of the page on the link below will give you some idea. As it states, the time varies depending on the battery size.
