Store a Lithium or LiFePO4 Battery Properly

How should I store the battery if I don't use it for several months?

Lithium and LiFePO4 batteries are designed for long life and reliable performance, but proper storage plays a crucial role in keeping them healthy—especially during seasonal downtime.
Whether you’re storing a battery over the winter or simply not using it for an extended period, following the right storage practices can help preserve capacity, extend lifespan, and ensure the battery is ready when you need it again.

Below are some simple, practical guidelines to help you store your battery the right way.

1. Store the Battery at 50–70% State of Charge

One of the most important rules for long-term storage is avoiding extreme charge levels.

• Do not store the battery fully charged
  
• Do not store it completely drained

The ideal storage range is 50–70% state of charge (SOC).
At this level, the battery cells experience less internal stress, which helps prevent capacity loss and supports long-term health.

If you purchased a non-Bluetooth version battery, you can estimate the remaining power based on voltage. Taking a 12V battery as an example:

For other types of batteries, the relationship between voltage and capacity is mentioned in the user manual. Please refer to the user manual for specific details. If you have accidentally lost the printed version of the user manual, you can download our user manual here：USER MANUAL

2. Disconnect All Loads and Chargers

Before storing the battery:

• Disconnect it from any chargers
• Disconnect all loads
• Turn off or disconnect Bluetooth monitoring if applicable
  
  

This prevents unnecessary power draw and ensures the battery remains stable during storage.

3. Choose a Cool, Dry Storage Location

Environment matters when it comes to battery storage.

• Store the battery in a cool, dry place
• Avoid direct sunlight
• Keep it away from moisture, heat sources, or freezing conditions
  
• Keep away from children and pets

Moderate temperatures help slow down chemical aging and protect internal components.

4. Check and Recharge Every 6 Months

LiFePO4 batteries have a very low self-discharge rate, but they are not completely immune to energy loss over time.

For best results:

• Check the battery every 6 months
• Recharge it back to 50–70%
• Store it again following the same steps above
  

Our batteries last up to 10 years, so learning how to preserve them is a very necessary thing.
This simple maintenance routine helps prevent deep discharge and keeps the battery in optimal condition.

When it’s time to use your battery again, it’ll be ready—powered up and dependable.
