Drone battery care is important. Not like the various batteries scattered round our houses, (the usual and generally discovered dry cell battery), drone batteries are Lithium-ion batteries, which include a selected set of processes and procedures for getting essentially the most out of them, whereas remaining secure.
In a typical week, as drone operators, we’re storing, charging, transporting, and discharging our batteries regularly, which quickly works in the direction of our batteries’ “finish of life”. With drones and drone batteries being as costly as they’re, it’s important to train correct care, to guard our drones and their batteries.
Beneath are a couple of steps outlining care in your drone batteries, which is able to extend the lifetime of the batteries.
Learn the drone producer’s handbook
At first, this may seem to be an appalling thought! “What, take out and skim the drone handbook?” “My drone doesn’t also have a handbook within the field!” Whereas this may seem to be a international idea for many people, the producer’s documentation gives a wealth of vital data on use and cost the batteries, in addition to upkeep, and storage, and likewise one thing we many occasions overlook, correct battery disposal.
In case your drone doesn’t have an included working handbook, it may be on-line as a downloadable file. Examine your drone producer’s web site for particulars.
Replace your battery’s firmware
This may come as a no brainer for the plane itself. Nevertheless, it is usually crucial to do that step for all of the batteries in your fleet as properly. For a lot of drones, if the batteries should not all on the identical firmware, the drone won’t take off in any respect.
How would one replace their batteries to the latest firmware? If there’s a battery firmware replace included within the present drone firmware replace, it is so simple as accepting the firmware replace with one set of batteries, working the replace, then putting in the subsequent set of batteries and working the firmware once more (as soon as prompted,) and repeating this course of for as many batteries as you might need for every of your plane.
If in case you have any batteries that aren’t updated, usually as soon as you set them within the drone, your drone’s flight app will provide you with a warning with an inconsistent firmware message, with a immediate to replace the battery. Fortunately many drone producers observe this course of for updating firmware, making it simple to maintain all of your batteries updated.
Be conscious of utmost temperatures
Residing in Central Florida, the one temperature extremes I fear about is excessive warmth. Many different operators worldwide should take care of extraordinarily low temperatures within the winter and excessive temperatures in the summertime.
No matter geographical location, excessive temperatures are detrimental to a drone battery’s well being. Due to this, at all times be certain to not retailer, cost, or function your drone batteries in extraordinarily sizzling or chilly temperatures. You could find the really helpful ranges (in Fahrenheit and Celsius) outlined by the drone producer in your operator’s handbook.
It was talked about that excessive temperatures are detrimental to drone batteries. How? Batteries which have been left in or utilized in areas which can be too chilly or too sizzling, can completely lower a battery’s capability, lifetime, and stability. An instance of this is able to be leaving batteries in a automobile throughout winter or summer time.

Use producer battery chargers
There are various third-party charging options obtainable for all kinds of drone producers. Though these appear to be a preferred alternative, particularly on account of their low-cost pricing, manufacturer-specific costs are designed to particularly work with that producer’s drone batteries.
Concern with utilizing third-party chargers come into play when the next are thought of:
- The drone charger could have a greater charging price than what the batteries require.
- The third-party charger may cost the batteries quicker, nevertheless, this quicker cost price could create excessive inside temperatures which may injury the battery elements and result in a decreased battery life.
- A 3rd-party charger won’t have guides or alignment with the battery, which may injury the terminals of the batteries.
- Many drone producer battery chargers have protections constructed into their chargers and batteries, thus making certain the battery life falls inside producer specs, whereas the third-party charger could not.
Observe charging finest practices
To finest care in your batteries, batteries must be allowed to return to the producer’s really helpful inside temperature earlier than charging. If the batteries have been left in a summer time sizzling or freezing automobile, it’s best to allow them to return to shut to room temperature earlier than charging.
Additionally, let the battery quiet down after a flight earlier than placing it on the charger. Nevertheless, as we all know typically within the discipline, it may be of utmost significance to get our batteries recharged as quickly as potential after simply discharging them in flight. With some producer chargers, it’s secure to plug in a battery even when nonetheless sizzling, supplied the charger and battery are in a well-ventilated space.
Most occasions, nevertheless, the battery will postpone charging (whereas on the charger) till the inner temperature has cooled all the way down to a really perfect temperature. All that stated, it’s nonetheless extremely advisable to let the battery quiet down first, earlier than inserting it on the charger.
Observe battery storage finest practices
The place to retailer the batteries
The perfect temperature to retailer most drone batteries is between 71° and 86°F (22 and 30°C). Storage between these temperatures may also help reduce battery capability loss.
Whereas it’s endorsed to retailer batteries at these temperatures, this won’t at all times be potential. If that is so, when potential, keep away from storing batteries in automobiles or storage models that can get highly regarded or very chilly, in order to not injury the batteries.
Partially discharge batteries earlier than storage
Though all of us wish to be in “prepared state” or “instant Go state”, you shouldn’t cost batteries to 100% earlier than storage, eager to be prepared “simply in case”. Many producers’ batteries are of the clever sort, which means they may mechanically discharge after a sure timeframe. Batteries that don’t self-discharge, or which can be saved with a full cost for an extended interval will incur injury to the battery cells.
Within the drone’s working app, typically you possibly can set the variety of days for the battery to self-discharge to the really helpful storage stage (in DJI drones this is able to be 60%). If there isn’t any choice so that you can set the times your self, the battery ought to start self-discharging at 10 days or so. In case you plan to retailer a battery and it’s beneath 60% it must be charged as much as the 60% vary first.
Keep away from flying to 0%
Identical to storing batteries at 100% can injury the battery, flying to 0% likewise may cause everlasting injury to your battery. I counsel that you just land your drone when the battery has reached 15% to maximise battery life. Nevertheless, many drone operators really feel extra snug with touchdown across the 25% mark, as a precaution. If for some motive your battery(s) has been depleted past 15%, it’s advisable to right away recharge the battery as quickly as potential.
Rotate battery utilization
This may seem to be a international idea to some. However rotating out batteries assist to increase their well being and life. For instance, let’s say you have got 3 batteries included in a “fly-more” bundle. Label the three batteries (1,2,3) and use them in that order. In case you are not flying all of the batteries in a single session, you’d use the subsequent one in line, so as. This helps in stopping the mistaken use of 1 battery, repeatedly over time, over the others, thus extending every battery’s life.
Drone battery upkeep
Upkeep is vital if you wish to maintain your batteries in prime working order and able to go for every flight. Beneath are a couple of steps to assist within the course of.
- Ensure that the cell voltage distinction is lower than 0.1V after the battery is absolutely charged and left stationary for six hours. This may be checked within the drone’s flight app.
- Ensure that the battery just isn’t swollen, leaky, or broken.
- Clear the battery terminals with a clear dry fabric and ensure they’re absolutely clear earlier than every use and earlier than charging.
- Ensure that the battery firmware is up to date to the newest model.
Battery points to concentrate on
If any of the next points are noticed together with your batteries, you should retire them and get rid of them correctly. Earlier than you begin complaining about the price of changing your battery, do not forget that utilizing a broken battery can lead to injury to your drone.
- The battery is noticeably swollen. You’ll be able to usually see this when the battery seems to be “puffy” or will now not snap in or sit flush throughout the drone.
- The battery is leaking or has visible injury (resembling cracks, tears, dents, or scorch marks).
- The battery has bent terminals.
- The drone’s working app notifies or prompts you concerning battery cell injury.
- The battery has gone by means of 200 charging cycles (the traditional life expectancy of a LiPo battery).
- The battery is exhibiting errors even after correct cost and discharge procedures, twice in a row.
Retiring batteries and secure disposal
As was talked about above, batteries which have reached 200 cycles must be retired. That is to make sure the security of the drone and others close by, because the battery might ultimately undergo failure. You’ll be able to perceive a drone battery cycle to imply each time the battery is charged. Many drone flight apps (ie: DJI Fly or DJI Go 4, Autel Explorer) give display screen readouts of the presently put in batteries’ cycle and voltage.
Correct battery disposal contains discharging the battery absolutely and immersing it in saltwater for 8-12 hours. Alternatively, you might have an area outlet that accepts Lithium-ion batteries for disposal. It’s advisable that you don’t ship your batteries to a disposal facility.
