Battery Thermal Run Away
A disaster avoided yesterday as my neighbor called and alerted me to an alarm going off in my coach and a strong sulfer smell outside. I went in the coach and the propanr /CO2 alarm was going off and it smelled like sulfer inside. I first thought of the batteries so went to remove the step that covers the battery area, The step was hot to the touch and when I removed it, smoke was pouring out of one of the coach batteries. I quickly removed the ground and then the positive cables from both coach batteries and removed them. I had just checked all batteries 3 days prior and serviced them in preparation for a 1500 miles trip coming up. It could of really been a disaster if this would have happened on the trip. The battery box is now cleaned and two new coach batteries are installed. Word to the wise: Inspect your batteries often and service them as required. The batteries were Interstate SRM27 Marine/RV Deep Cycle models with a Mfg date of 2013. Due to my wifes health, the coach has been sitting in my driveway for the last 3 years. I run it monthly and check the batteries at least every couple months. I also leave the coach plugged in and the 10W solar panel is going.
