I’ve noticed a peculiar trend with the Titan Twin chargers and the Dionic 90 batteries. I’m going onto my third Twin charger in about 6 years. My first charger was used in the truck with an Prosine 1000 (pure sine wave) inverter, and vibrations caused the socketed ROM chip to come loose – super easy fix. But then one side failed to charge… it will indicate charging with a red light but wake up in the morning and the LCD display on the battery tells you the battery has not been charged at all. Once this intermittent failure begins, the same side’s LEDs periodically flash like it’s detected a battery.
… Now onto my second charger failure. This time the new charger is always in my house, always on a OneAC medical-grade power conditioner plugged in with all my other battery chargers. It’s happening again!
I noticed that the failed charging side may corrupt an older Dionic’s on-board computer or the other way around. I have two ‘corrupted’ Dionic 90’s that even pushing the reset button doesn’t help – on one, the LCD is stuck in Autocal indication, the other just drops from 60-40% to 0% in seconds. Granted the batteries are 3 years old and near EOL but discharge tested actual 3Ah capacity on a Quad charger – still good for a few VOs on the PMW-350 that sips less than 20watts.
I’ll send off an email to Anton Bauer but just want to see if anyone else has run into this issue as well?
