Good possibility you need to change the charging algorythm for your new batteries. It could already be loaded into the charger, you may need to enable it.
Attached: instructions for changing algorythm, if already loaded.
Attached: List of algorythms fro Delta Q. I don't see your battery number.
I don't see your battery listed. You may need to contact them for help.
