How to Correctly Store Aircraft Batteries

Proper storage of aircraft batteries is essential for maintaining their performance and extending their lifespan. In aviation, where reliability and safety are crucial considerations, ensuring that batteries are stored correctly can prevent operational issues and potential hazards down the line. In this blog, we will explore the various aspects of aircraft battery storage, including why it is so important and the basic practices that should be followed to maintain their optimal health.

Aircraft batteries are designed to deliver the necessary power to start engines and support electrical systems. Though they are specifically designed to withstand the rigors of flight, they require proper maintenance and storage to remain in good working condition just like any other type of battery. Lead acid batteries are the type commonly used in aircraft, and a main issue that can arise with them is sulfation, a condition where lead sulfate crystals develop on the battery plates. Additionally, improper storage conditions can lead to the deterioration of the battery’s internal components, potentially causing failures. As such, storing batteries in an appropriate environment and maintaining them correctly can be a significant help in upholding their capacity and performance.

One key practice is choosing the right storage location. Aircraft batteries should be stored in a cool, dry environment, shielded from extreme temperatures and high humidity, as these factors can adversely affect their performance and lifespan. The ideal storage location is a temperature-controlled area where there is no chance of overheating, freezing, or excessive moisture, all of which can significantly degrade a battery and compromise its reliability.

Another critical aspect of battery maintenance is performing a complete charge before storage. A fully charged battery is less likely to suffer from sulfation and other forms of degradation compared to a partially charged one, so a quality battery charger designed for lead acid batteries should always be kept on hand. Additionally, disconnecting the battery during storage helps prevent unnecessary discharge and minimizes the risk of accidental short circuits. Before disconnecting, it is prudent to use a digital multimeter to check that the battery’s voltage is within the recommended range and verify that it is not over or under charged. After confirming the voltage, turn off the battery switch and carefully remove the connections to safeguard the battery.

As with any other aircraft components, the periodic testing and maintenance of batteries is crucial. Like we previously touched on, regularly checking the battery’s voltage and specific gravity using a battery hydrometer provides valuable insights into its health. Similarly, a battery capacity tester can evaluate an aircraft battery's ability to hold and deliver a charge over time by measuring its capacity against its rated specifications. A battery analyzer performs an even more comprehensive diagnostic by testing various parameters like voltage, internal resistance, and overall health. It can identify issues like cell imbalance, deteriorating performance, and potential faults before they escalate into significant problems. Regular maintenance checks, therefore, play a key role in detecting and addressing problems early.

In addition to these testing tools, a battery terminal cleaning kit is extremely helpful for maintaining the cleanliness and security of battery connections. It typically includes brushes for removing corrosion and debris, cleaning solutions to dissolve grime and oxidation, and abrasive pads to create a smooth contact surface. By using such a kit, you can prevent poor connections and ensure the reliable performance of an aircraft’s battery system.

In conclusion, following these best practices for correctly storing aircraft batteries and using appropriate tools to test and maintain them can significantly extend their lifespan, keeping them ready for flight.
