This all started with a very sluggish slides on my 2023 3100RD I thought it was the battery, so I purchased a new Interstate 750 cranking amp marine battery and replaced the old battery. Within 3 months the new battery had dead cells. It showed 13.5 volts but all the cells showed very low using a battery cell tester. Upon further diagnosis I discovered that the battery monitor showed that the battery had 13.5 volts but also showed 10.5% charge and .5 amps. I also own a 2022 22MLE, so I removed the battery from that unit and put it in the 3100RD. It also showed the same results, so I put the 3100RD battery in the 22MLE and It showed 100% charge and 100ah. I thought that there may be something wrong with the charge controller so I swapped them. (no difference). The problem seems to be in the 3100RD, Any ideas?
