There are a few potential causes for an RV battery to overheat:
1. Overcharging: If the battery charger or alternator is malfunctioning and providing too high of a charging voltage, it can cause excessive gassing and heat buildup in the battery.
2. Excessive current draw: If there is a very high electrical load on the battery, like trying to run too many appliances at once, it can cause excessive current flow and internal heating.
3. Poor ventilation: RV batteries need proper ventilation to dissipate heat. If they are installed in an enclosed, unventilated compartment, heat can build up.
4. Advanced age/damage: As lead-acid batteries age and sustain wear, their internal resistance increases, causing more heat during charging and discharging.
5. Loose battery connections: Loose battery cable connections can create resistance and generate heat at the connection points.
6. Ambient temperature: Operating batteries in very hot conditions, like in direct sunlight, can compound heating issues.
To prevent overheating, it's important to ensure proper battery charging, manage electrical loads, provide adequate ventilation, replace aged batteries, keep connections clean/tight, and avoid exposing batteries to high heat sources. Monitoring battery temperature can also help detect overheating issues early.
