Mastering Battery Care: How to Store LiFePO4 Batteries for Longevity


Discover the essential steps to properly store and maintain your E&J lithium batteries. Effectively storing your batteries during periods of non-use is crucial to ensure their longevity and optimal performance when you start using them again. Whether you utilize your lithium batteries seasonally, such as in an RV or on a boat during the summer, or plan for an extended storage period, following the correct storage practices will help keep your batteries in excellent condition.

Winterizing Your Lithium Batteries

For those who use their lithium batteries seasonally, it’s vital to winterize them correctly to ensure their health and performance for the next season. Improper storage of lithium batteries can potentially cause damage. The first and most crucial step is to bring the batteries to at least a 50 percent state of charge. Never store your lithium batteries empty, as lithium iron phosphate batteries self-discharge at a rate of approximately two to three percent per month. Storing your batteries empty may lead to discharging levels that cannot be protected by the Battery Management System (BMS). If you plan to store your lithium batteries for an extended period, it’s best to charge them to 100 percent.

Disconnecting the Batteries

Many RVs and other vehicles have components running in the background, such as CO2 sensors, backlit stereos, or emergency sensors that may bypass the main disconnect switch. To ensure the battery is not being discharged while in storage, it’s advisable to physically disconnect the main positive and negative wires from the lithium batteries. While this step is not entirely required due to the minimal self-discharge of lithium batteries, it is recommended for added peace of mind.

Maintenance-Free Storage

Unlike lead-acid batteries, lithium iron phosphate batteries do not require a trickle charger during storage. E&J lithium iron phosphate batteries are maintenance-free, meaning you don’t need to take any additional actions. Simply follow the aforementioned steps, and your batteries will be ready for use when you need them again.
