2014 elxd soc meter

2014 elxd. Having trouble with setting the state of charge meter.

Put new Fullriver AGM batterys in. DC180-8 8 volt. Charger has had the algorithm changed.

I have tried to change the state of charge meter to 99. Have not been able to get 100 because of the blinker. When charging the lcd display shows 89. Charger shuts off has green light. Turn car on battery meter is missing 1 bar.

Any help would be greatful.
