A drone\u2019s battery is truly a crucial component. Care for it well and you will both prolong its life and optimise the coverage of every UAV mission you fly. But treat it poorly and, one way or another, your operation\u2019s performance is likely to suffer.\u00a0Waypoint spoke with senseFly\u2019s expert team of support engineers to nail down what great battery care looks like. Charging your drone battery \tWhen you receive a new drone battery, if you plan to use it right away, charge it up to 100%. If not, it\u2019s optimal short-term storage level is 70% (intelligent charging units, such as the senseFly SmartCharger, enable this kind of charging precision). \t1-2 days before your battery\u2019s first operation, charge it up to 100%. Then, when your flights are over, charge your battery again to 70% until its next use. \tIf you notice a significant drop in your drone\u2019s available flight time after fully charging one of your batteries, do not continue to use or charge that battery. Such a reduced power capacity can indicate an internal fault. \tImmediately after flight, your UAV\u2019s battery may be hot. To avoid potential damage, wait until the battery is cool enough to hold in your hand before charging it again. \tIf possible, always charge batteries in a LiPo guard bag (see image below) as these are designed to limit the spread of fire or explosion. \tNever charge a swollen battery, one that is leaking or one that has been damaged. \tIf you notice a suspicious smell, noise, or smoke emanating from your battery or charger, disconnect it immediately. \tOnly charge your UAV\u2019s battery with a manufacturer-approved charger. Do not attempt to charge your drone battery with any other unit. \tNever use a damaged charger. \tSince there is always some degree of risk that a battery will catch fire, do not charge batteries near \ufb02ammable materials, or on \ufb02ammable or conductive surfaces such as carpets, car seats, wooden \ufb02ooring or wooden furniture. Try to charge batteries on nonflammable and nonconductive surfaces, such as in a large ceramic bowl. \tWhile charging, do not leave the battery unattended, do not cover it or store it near a source of heat. \tDo not attempt to charge a battery if the ambient temperature is below 0\u00b0 C (32\u00b0 F) or above 40\u00b0 C (104\u00b0 F), or if it is still installed inside your drone. \tPro tip:\u00a0for efficient battery management, label each battery with a number (think: magic marker or stickers). That way, you can note down each battery\u2019s charging status. Plus, you\u2019ll know at a glance which battery was used for each flight, which is useful when logging your operations. The ideal way to charge a drone\u2019s battery? Inside a battery-safe LiPo guard bag. Storing your drone battery \tDo not keep a LiPo battery either fully charged or discharged for more than a month. If you need to store a battery for a while and its level of charge is too high, use up some power with a short flight. If too low, charge it back up to 70%. \tDo not leave a battery in your drone for extended periods of time. When possible, store batteries in the drone\u2019s case instead. \tIf you need to store your batteries elsewhere, avoid direct sunlight and store them in a cool indoor location. Safe handling of your drone battery \tAvoid all contact with battery electrolyte\u2014an electrically conductive liquid solution inside the battery\u2014as well as electrolysis vapours. In the event of a battery leak, do not allow your battery\u2019s contents to come into contact with your skin or eyes. \tIn case of contact with the skin, wash copiously with soap and water. \tIn case of contact with the eyes, rinse copiously with cold water, then consult a doctor. \tIn case of inhalation of electrolysis vapours, seek medical help immediately. \tInspect your batteries and charger regularly for damage to the cable, plug, enclosure or other parts. Do not use the battery if the plastic cover has been torn or compromised in any way. \tDo not expose the battery to excessive physical shock such as impact (try not to drop it!) or crushing force. Equally, do not place any heavy objects on your battery or charger. \tKeep batteries out of reach of children. \tDo not allow your drone battery to come into contact with any kind of liquid. E.g. do not leave your battery\/drone out in the rain or near a source of moisture. \tDo not put your battery in a microwave oven or a pressurised container. \tDo not attempt to dismantle, pierce, distort or cut the battery and do not attempt to repair the battery or charger. \tDo not transport batteries in the hold of an aircraft, or any other area of an aircraft that is inaccessible during \ufb02ight. Transport them in your hand baggage or preferably in a battery-safe bag. When flying If you know you\u2019re going to be flying, plan ahead. (Image:\u00a0RDO Equipment) \tPlan your drone\u2019s flights so that they are comfortably within the limits of the battery. \tPro tip:\u00a0leave a little extra time at the end of each flight in case your drone needs a little extra power for any reason, for example, to counteract strong winds or to hold its position while waiting for the landing zone to clear. \tThe lower you push a battery\u2019s charge\u2014hitting regularly below 20%\u2014the shorter that battery\u2019s life, and the lower its reliability, will be. \tIn low temperatures, or when there are strong winds, adapt your missions with shorter flight times in mind\u2014when winds are strong, your drone uses more power, while low temperatures cause the chemistry of the battery to change and it to discharge more quickly. \tIn cold conditions, where the air temperature is below 5\u00b0 C (41\u00b0 F), try to keep your UAV\u2019s batteries warm\u2014ideally at least 5\u00b0 C\u2014before connecting them to your drone. Disposing of your drone battery Correct disposal of damaged batteries. \tDo not discard of batteries with household or commercial waste\u2014this harms the environment. \tDamaged or unusable batteries must be disposed of properly, for example, in a container specially reserved for this purpose, following appropriate local guidelines and regulations (see image above). For more information, contact the distributor from whom you purchased your drone or your local municipal authority. \tDo not dispose of a battery by setting it on fire.
