Aircraft batteries are essential for starting the engine, powering the electrical systems, and providing backup power in case of an emergency. But they also require regular maintenance to ensure their optimal performance and safety. In this article, you will learn what tools you need to maintain your aircraft battery and how to use them properly.
Before you begin any battery maintenance, you need to protect yourself and your aircraft from potential hazards. You will need gloves, goggles, and aprons to prevent contact with corrosive battery acid and electrolyte. You will also need a fire extinguisher, a spill kit, and a ventilation fan to deal with any fire, spill, or gas issues. Additionally, you will need a multimeter, a hydrometer, and a thermometer to measure the voltage, specific gravity, and temperature of the battery cells.
Maintaining aircraft batteries is paramount for safety. Essential tools include a digital multimeter to measure voltage and capacity, battery hydrometer to check electrolyte levels, and a load tester for assessing performance. Personal protective equipment like gloves and safety glasses are crucial. Regular inspections, following manufacturer guidelines, and using proper torque tools for maintenance contribute to reliability. Adhering to safety protocols during battery handling minimizes risks, ensuring optimal equipment functionality and overall flight safety.
A battery charger is a device that restores the charge of a discharged or low battery by applying an electric current. You will need a battery charger that is compatible with your battery type, size, and voltage. You will also need to follow the manufacturer's instructions for the charging rate, duration, and mode. You should monitor the battery charger during the charging process and disconnect it when the battery is fully charged or overheated.
A battery tester is a tool that evaluates the condition and capacity of a battery by applying a load and measuring the voltage drop. You will need a battery tester that can handle the load and voltage of your battery. You will also need to perform the test in a safe and controlled environment, following the manufacturer's specifications and procedures. You should compare the test results with the baseline values and determine if the battery needs to be replaced or serviced.
Aircraft battery maintenance involves using essential tools like the hydrometer for specific gravity measurement, load testers for performance evaluation, Voltage and capacity testers gauge cell voltage, while cell checkers identify issues in multi-cell batteries.
A battery cleaner is a product that removes dirt, grease, and corrosion from the battery terminals and cables. You will need a battery cleaner that is suitable for your battery material and does not damage the battery case or seals. You will also need a brush, a cloth, and a wrench to apply the cleaner and loosen or tighten the connections. You should clean the battery regularly to prevent poor contact, resistance, and leakage.
A battery filler is a device that adds distilled water to the battery cells to maintain the proper electrolyte level. You will need a battery filler that has a spout, a valve, and a bulb to control the flow and amount of water. You will also need to check the electrolyte level before and after filling, using the indicator marks on the battery case or a hydrometer. You should fill the battery only when it is fully charged and cool.
When maintaining and storing aircraft batteries, one shall strictly follow OEM instructions to avoid damage to the equipment and possibile environmental contamination. Battery charging and storage has a very specific procedure that must be followed step by step. If a battery loses its charge below a certain voltage, it will go to Locked mode and no charging will be possible unless it is sent to the manufacturer which is a very challenging task due to the nature of the aircraft batteries which put them into Dangerous Goods category and normal shipment through airfreight is not possible without so many pre requisites.
A battery storage is a place where you keep your battery when it is not in use or during long periods of inactivity. You will need a battery storage that is dry, cool, and well-ventilated to prevent damage, deterioration, or self-discharge. You will also need to disconnect the battery from the aircraft and attach it to a trickle charger or a float charger to maintain its charge. You should inspect the battery periodically and recharge it if necessary.
