I have just purchased a 2005 gem it had all gel bat. That were all bad .I installed all new deka acid bat. …the charger is the delta Q charger. I’m I ok or does my charger have to be reprogramed for acid bat.

Yes, the algorithm must be changed for wet batteries. The procedure is covered in the manual below.

I recall that the charge algorithm for wet batteries calls for a higher finish voltage. This would result in wet batteries being undercharged if used with a charger set to a dry battery algorithm. This will not, however damage wet batteries. Just don’t try to charge dry batteries on a charger set for wet. That would result in an overcharge and eventual damage.
