For storage without shore power or another active charging source, set the RV house-battery disconnect to OFF/STORE to isolate the battery from RV loads. Use ON/USE only when the battery must stay connected to a verified maintenance-charging path; whether shore power requires that setting depends on the RV's wiring.
Set the disconnect for storage
- Turn off loads. Switch off lights, appliances, and other house-battery loads.
- Check charging. Unplug shore power or identify the maintenance-charging source and confirm how it is wired to the battery. If keeping that charging path active requires the disconnect to remain on, use ON/USE; otherwise, use OFF/STORE for unpowered storage.
- Isolate the house battery. Set the disconnect to the position that disconnects it from RV loads. Labels vary, so follow the intended electrical state rather than assuming a particular label always means isolation. Confirm that essential devices you need are not unintentionally disabled. The house-battery disconnect may not isolate the chassis battery or every load in the RV.
- Monitor the battery. Isolation reduces parasitic loads but does not stop cell self-discharge or power use by the battery management system. During prolonged storage, a lithium-ion battery's pack voltage can fall from these causes; falling below its recommended discharge-voltage limit can cause overdischarge, with potential safety and performance consequences, as CALCE explains. The Vipboss 12V 105Ah Bluetooth LiFePO4 battery includes Bluetooth monitoring that can help you check battery status during storage.
FAQs
Should the RV battery disconnect be off during storage without charging?
Yes. For storage without shore power or another active charging source, use OFF/STORE to isolate the house battery from RV loads.
When should the RV battery disconnect remain on during storage?
Use ON/USE only when the battery must remain connected to a verified maintenance-charging path and the RV's wiring requires that switch position for charging.
Does turning the RV battery disconnect off stop all battery discharge?
No. Isolation reduces parasitic RV loads, but it does not stop cell self-discharge or power used by the battery management system, so continue checking battery status during prolonged storage.
