Need Battery/charging expert. 2021 Dynamax ISata5. Has 3 AGM RV batteries in coach in parallel. Have had no previous electrical problems. Over the past couple of weeks, I've had coach out of garage, unplugged, while working on stuff in shop a couple of times. Always put back in shop at night and have forgotten to plug in for 1-3 days. After plugging in, charging system goes on full bore pulling large amperage. Charger screen would read "Absorption Charging/14+ volts" and "50+ amps". While the charging was happening, it was generating a decent amount of heat/odor in the garage. Then comes this morning.....
Had it out of shop yesterday and pulled in in last night....forgot to plug it in again. Remembered this morning about 4am and plugged it in. Went back in house for 2nd cup of coffee. Went back into garage about 6am, garage was "full" of fumes (very strong odor), CO2 detector going off in coach signaling "propane" odors (didn't smell like propane but definitely strong chemical smell). One of the three batteries was "very warm" to the touch...just short of HOT. It also sounded like it was boiling/gurgling on inside. Charger was on "Absorption Charging/14.6V/56 AMP", incoming feed was reading 9 AMPs on line 1.
Fearing a battery was preparing to explode, I turned off charger, turned off battery switch and ventilated garage and coach.
So, what do you think?
1. One bad battery getting ready to explode on off gassing?
2. Charger malfunction and over charging?
3. Recommendation?
Thanks for the read!
