I also have an elcon charger that needed to be reprogrammed, I reached out to Elcon and they had me send the battery information and the charger to them. The charge for me was $5 to reprogram.
If you haven't sent them an email with the alg information and the next few lines on the white sticker from the charger and they should reach out to you.
