I think my charger is a 4 stage. Are you saying my charger is good or bad?

How do you desulfate lead plates?

Do a Google search on "equalizing wet cell batteries."

Re: Getting ready to add shore power

I wonder what the difference is between bulk and float when the max output of the charger is either .75 amps or 1.5 amps, even if it is a "4" stage charger.

From what I understand a float charger does not actually charge. It keeps a fully charged battery fully charged. The battery charger I have will charge the battery as well as maintain it once it is fully charged.

Yes, but with such a small output it will take a long, long, long time. Days if the battery is down much.

A battery monitor as an example considers a battery fully charged when the current is less than 2% of bank size. Your charger is smaller than that 2%.

After a day of sailing it typically took no more than a few hours to charge. With that being said the only instrument I am using is my depth sounder. Now with a stereo installed I may need to up my charger to something a little bigger.
