I have 2 4D Lifeline batteries. I bought them new last Augaust before
we left for Mexico.

I have done a 5 hour 15.5 volt
equalization and it now goes down to about 80 amps before it reaches
12.1 volts.

Any suggestions would be helpful.
We are hoping to go to Hawaii in May from La Paz.

John,
Over voltage or overcharging can damage AGM batteries. You need
some reliable information on AGM batteries and correct charging
procedures. I am not an expert and I have not used AGMs yet.
Try the battery manufacturer's web site or ask some place like
West Marine's support for correct charging procedure..
