Accurate Diagnosis of the Drone Battery Level Indicator
In the drone world, battery failure is one of the most common incidents that can compromise a mission or even the safety of the equipment. Accurately diagnosing the battery level indicator is therefore an essential prerequisite for ensuring a trouble-free flight. A motor that struggles to start or a dim light often indicates a low battery, which can be problematic during takeoff. To fully understand the source of the anomaly, it is important to adopt a systematic approach. This approach begins with a careful inspection of the condition of the terminals and terminals. Oxidation, visible as a white or greenish powder, can cause poor contacts and disrupt power transmission. Cleaning these contacts with sodium bicarbonate mixed with water removes these deposits that hinder the battery’s proper functioning. Using a light layer of grease or petroleum jelly helps prevent new oxidation from appearing, thus ensuring greater longevity.
The diagnosis then moves on to electrical testing. Measuring the resting voltage with a multimeter provides valuable information. A well-charged battery should display a minimum voltage of 12.4 V for EFB types and slightly higher for AGMs. When the voltage drops below this level, it is necessary to recharge or retest the battery with a capacity tester. This device applies high instantaneous current to measure charge retention, and therefore the quality of the electrodes. For example, a rapid drop in voltage often indicates plate sulfation, indicating advanced aging and the need for replacement.
This diagnosis is all the more crucial given that battery quality varies depending on the brand and technology. Renowned manufacturers such as Varta, GP Batteries, and Ansmann offer specialized ranges that offer different performance levels, particularly in terms of resistance to deep discharge or extreme temperatures. Based on these assessments, it becomes possible to anticipate failures and choose a battery suited to the specific requirements of the drone and the mission.
