The Battle Born Educational Series | Charging & System Behavior
Proper storage is essential to keep your LiFePO4 batteries performing at their best during the off-season.
Lithium batteries are well-suited for long periods of inactivity, but taking a few simple steps before storage helps preserve performance and ensures your system is ready when you return.
Start with State of Charge
Before storing your system, bring your batteries to a full charge.
Once fully charged, disconnect them completely from all loads and charging sources. This includes:
- Inverters
- Battery monitors
- Any small parasitic loads
Even minor draws can slowly drain the battery over time if left connected.
By fully disconnecting the system, you ensure the battery retains its charge during storage.
Take Advantage of Low Self-Discharge
One of the advantages of LiFePO4 batteries is their very low self-discharge rate.
Once disconnected, they can sit for extended periods, often months, without requiring constant attention or recharging.
This makes them ideal for seasonal use in RV applications.
Store Within a Moderate Temperature Range
Temperature plays an important role in long-term storage.
For best results, store your batteries in a moderate environment, ideally between approximately:
-
32°F and 95°F
Short periods outside this range are generally acceptable, but prolonged exposure to extreme heat or deep cold can impact long-term performance.
Maintaining a stable environment helps preserve battery health over time.
Cold Weather Considerations
If your RV is stored in colder climates, LiFePO4 batteries can remain in place without issue.
However, it is important to remember:
-
Do not attempt to charge the batteries below approximately 25°F
Charging at low temperatures is restricted to protect the battery. If temperatures are below this threshold, wait until conditions improve before reconnecting charging sources.
Periodic System Checks
While lithium batteries require minimal maintenance during storage, it is still a good idea to check the system periodically.
Every few months:
- Confirm the batteries are holding voltage
- Ensure they have not been left connected to any load
These quick checks help ensure the system remains in good condition throughout the off-season.
Preparing for Use Again
When you are ready to use your system again:
- Reconnect all system components
- Check connections and wiring
- Top off the battery charge if needed
Because of their low self-discharge and stable chemistry, LiFePO4 batteries are typically ready to return to service with minimal preparation.
The Bottom Line
Proper storage of LiFePO4 batteries is simple but important.
By fully charging the battery, disconnecting all loads, storing it in a moderate environment, and performing occasional checks, you can preserve battery health and ensure reliable performance when your next trip begins.
Lithium batteries are designed for long-term reliability, and with proper storage, they can sit idle and return ready to perform when needed.
