drone battery

Drones have revolutionized various sectors, from aerial surveying, inspections, monitoring to assisting in agriculture. Their efficiency, accuracy, and safety are unparalleled compared to traditional methods. Central to a drone’s performance is its lithium polymer battery, which boasts high energy density, compactness, lightness, high safety, and cost-effectiveness. Given its significance, proper maintenance and emergency handling of drone batteries are crucial.

Routine Maintenance Tips:

  1. Regular Inspections: Periodically inspect the battery body, handles, wires, and power plugs. Check for any visible damages, deformities, corrosion, discoloration, or wear and tear. Ensure that the connectors between the battery and the drone are not too loose.
  2. Cleanliness: After every use, wipe the battery’s exterior and power plug with a dry cloth to remove any dust or impurities. This prevents corrosion and ensures optimal performance.
  3. Temperature Management: If the battery is warm post-flight, wait until its temperature drops below 40°C before charging. The optimal charging temperature range is between 5°C to 40°C. Charging the battery once it has cooled can significantly enhance its lifespan. During summers, avoid exposing the battery to direct sunlight. In winters, after discharging, use effective insulation methods, like thermal boxes, to keep the battery above 5°C. Batteries tend to have a reduced lifespan in cold environments.

Emergency Handling: In the event of emergencies, such as a battery catching fire during charging:

  1. Immediate Actions: First, disconnect the power source. Using asbestos gloves or tongs, remove the burning battery and place it on the ground or in a fire sand bucket. Cover the burning lithium battery with an asbestos blanket and then layer it with fire sand to suffocate the fire.
  2. Battery Disposal: If you need to dispose of a depleted battery, immerse it in saltwater for over 72 hours to ensure complete discharge. Once dried, proceed with disposal.
  3. Fire Extinguishing: Use carbon dioxide fire extinguishers as they don’t pollute the environment or corrode machinery. However, they only provide momentary fire suppression. It’s best to use them in conjunction with sand and asbestos blankets to suffocate the fire effectively.

In conclusion, understanding and implementing routine maintenance and emergency handling techniques for drone batteries is imperative for every drone operator. It not only enhances the battery’s cyclic lifespan but also ensures the drone’s optimal performance, reducing operational costs and maximizing profits.
