Ok Did not see posts til one hour. Am I shutting down every 15min to check voltage and restarting until I reach 15v on the battery? And when I shut down, how long do I need wait to measure the battery?
Keep the Mega Watt on until you see 15.0V. After the V goes to 15.0V, set a timer and run the MegaWatt for 15 more minutes at 15.0V... that last 15 minutes is the top charging portion that does the dirty work cleaning up most of the sulfation on the plates, if there is some there.
Note I said "most of the sulfation"... not all. To get it really, all clean, requires an equalization charge. You disconnect the batteries from your rig to do an equalization charge, because it's done with 15.7 to 16.0V , requires you to baby sit the first few times you do it to see what is normal, time wise, and is done much less frequently, and you really should check the SG when you are done with doing an equalization, to see if your cells specific gravity truly are closely equalized.
As for your situation, I would top charge your batteries daily, if you can, Monday thru Friday, with this 15V then 15 minute timing routine, and then lets see what the SG is on your batteries, per cell, on Saturday Morning, after it's 6th daily top charge. Ask Mex to suggest what your SG readings should be. You do have or own a good hydrometer, don't you?
Also, maybe post up some pics of your Mega Watt rig in action, or maybe a short video.
