Battle Born batteries are renowned for their durability and performance in various applications, from RVs to solar setups. However, like all lithium batteries, they can experience a low-voltage disconnect (LVD) if they discharge below a certain voltage threshold. This safety feature protects the battery from damage due to over-discharging but requires specific steps to reinitiate the battery's functionality. In this comprehensive guide, we will provide you with a detailed, step-by-step process to wake up your Battle Born battery and ensure it performs optimally.

Step 1: Disconnect All Battery Connections

The first critical step in addressing a low-voltage disconnect in a Battle Born battery is to disconnect all connections from the battery. This includes:

• Positive and negative terminals: Safely remove any cables attached to both the positive (+) and negative (-) terminals of the battery.
• Connected devices: Unplug any devices or systems that are connected to the battery. This ensures that no current is flowing through the battery and prevents any potential interference during the reactivation process.

By completely disconnecting the battery, we prevent any accidental short circuits and prepare the battery for a thorough check.

Step 2: Wait and Check Battery Voltage

After disconnecting the battery, wait for 30 minutes before proceeding. This pause allows any residual charge to dissipate and ensures a more accurate voltage reading. Following the waiting period:

1. Measure the voltage of each battery individually using a reliable multimeter. This step is crucial as it determines the appropriate next actions.
2. Record the voltage readings to guide the next steps in the reactivation process.

Step 3: Charge Batteries with a Lithium Charger

If the voltage of a battery is found to be over 11.5V, proceed with the following:

1. Use a lithium-compatible charger: Connect the battery to a lithium battery charger specifically designed for lithium-ion batteries. This type of charger ensures the correct charging parameters are used, which is essential for the health of the battery.
2. Charge the battery: Allow the charger to fully charge the battery. Charging it correctly will help restore its functionality and extend its lifespan.

Note: Always ensure that the charger is compatible with Battle Born batteries to avoid any potential damage.

Step 4: Address Batteries Below 11.5V

For batteries with a voltage reading below 11.5V, follow these steps:

1. Connect to a 12V Source: Use a 12V power source, such as a jump-starting device, to gently revive the battery. This process is akin to jump-starting a car battery and can help bring the voltage up to a level where it can be charged effectively.
2. Idle for 15 Minutes: Allow the battery to stay connected to the 12V source for approximately 15 minutes. This action will help to slowly increase the voltage.

Step 5: Recheck Voltage and Charge Accordingly

After the 15-minute period:

1. Recheck the battery voltage using your multimeter.
2. If the voltage is over 11.5V: Proceed to charge the battery with a lithium charger, as previously described. This will ensure that the battery is fully reactivated and ready for use.
3. If the voltage remains below 11.5V: The battery might be too deeply discharged to recover through standard procedures. Contact Battle Born tech support for further assistance. They can provide additional guidance or recommend solutions based on the battery's condition.

Step 6: Reconnect and Reintegrate Batteries

Once each battery has been successfully charged and restored:

1. Verify voltage levels: Double-check the voltage of each battery to ensure they are all above 11.5V before reconnecting them.
2. Rewire the batteries into the system: Carefully reconnect the batteries, ensuring that all connections are secure and correctly configured.
3. Test the system: Once the batteries are reconnected, test your system to confirm that everything is functioning properly.

Best Practices for Battery Maintenance

To prolong the lifespan of your Battle Born batteries and minimize the risk of low-voltage disconnects:

• Regular monitoring: Periodically check the battery voltage to catch potential issues before they become serious problems.
• Use compatible chargers: Always use chargers specifically designed for lithium batteries to prevent overcharging or damaging the cells.
• Avoid deep discharges: Prevent the battery from discharging below 20% to reduce the risk of LVD and maintain battery health.

Conclusion

Waking up a Battle Born battery from a low-voltage disconnect requires careful attention to detail and adherence to proper procedures. By following the steps outlined above, you can successfully reactivate your battery, ensure it operates correctly, and extend its operational life. Proper maintenance and monitoring are key to avoiding future issues and ensuring your battery remains in top condition. By diligently applying these methods, you can maintain the high performance and reliability of your Battle Born battery, safeguarding your investment and optimizing your energy systems.
