apctest is a program that allows you to talkdirectly to your UPS and run certain low-level tests, adjust various settingssuch as the battery installation date and alarm behavior, and perform abattery runtime calibration. Here we describe how to use it for a SmartUPSutilizing the apcsmart driver and RS232 serial connection.The menus and options for USB, MODBUS, and simple signaling UPSes are differentbut mostly self-explanatory.
2. If after a self-test, the UPS does not detect that the battery has beenreplaced, you can use apctest to do a soft battery runtime calibration.For details of doing this, refer to the "Soft" Runtime Calibration sectionbelow.

3. If after the soft battery runtime recalibration, the UPS does not detectthat the battery has been replaced, you will need to do a manual batteryruntime calibration. For details of doing this, refer to the "Manual" RuntimeCalibration section below.
Perform a Runtime Calibration. This is a manual procedure andshould not be confused with the runtime calibration performedthrough PowerChute plus [or apctest]. The batteries inside of theSmart-UPS are controlled by a microprocessor within the UPS.Sometimes it is necessary to reset this microprocessor, especiallyafter the installation of new batteries. Stop the PowerChute plus[or apcupsd] software from running and disconnect the serial cable.There must be at least a 30% load attached to the UPS during thisprocedure, but the process will cause the UPS to shut off and cutpower to its outlets. Therefore, attach a non-critical load to theUPS and then force the UPS on battery by disconnecting it fromutility power [suggest not disconnecting, but simply turning offutility power thereby preserving earthing]. Allow the unit torun on battery until it turns off completely. Make sure a 30% loadis present! Plug the UPS back into the wall outlet [switch utilitypower back on] and allow it to recharge (it will recharge more quicklyturned off and with no load present). Once the unit has recharged,the "runtime remaining" calculation should be more accurate.Remember that if the unit is an older model, then the runtime willnot improve significantly.
It is unnecessary to subject a battery bank to an excessively longcalibration. Remove battery packs or increase the load (space heatersare good dummy loads) to obtain a reasonable time length for thecalibration (under an hour if possible).
The unit will then go to battery power until the capacity is 25%. Afterthis run time has been completed, the original Estimated Run Time is comparedwith the actual run time. It will then increase or decrease this value tocorrespond to the new run time achieved. If, at any time during the discharge,one of the following rules is violated the calibration will be aborted orcorrupted:
In some cases none of the battery runtime calibration methods result inthe UPS reporting a reasonably correct battery runtime. It has beenspeculated that this is because the battery constant value has driftedso far from normal that the microprocessor in the UPS cannot correct it.
This tutorial walks you through how to setup the Radiomaster TX16S radio. I will try to explain everything you need to know how to use the TX16S for the first time, including battery, radio settings, model setup and gimbal calibrations.
Is there a way to calibrate my receiver battery sensor on my tx16 for my Quadcopter battery voltage, I plug in a full battery and on the page that shows me all my Telemetry information like Crossfire strength and satellite count ,etc.but my quadcopter battery is fully charged and it only shows 78% .instead of 100.
Hello, first thabks a lot for the very valable information you gather here and make very easy to understand.
However, I m building a battery pack for ebike and wondering if it makes sense having a standard BMS that will balance at full charge 4,2V probably and a charger set to 90% so 4,0V ? So I wont have a balanced pack over the time... My main concern is to have a long life cycle battery. I ll use Sanyo NCR18650GA fin a 10.5ah 36V pack. I know of Smart BMS that can set balancing voltage, but they are expensive and I heard their bluetooth consume extra battery. Thanks ahead for your help
Does it feel like your battery charge's duration isn't as much as it used to be? If the battery just doesn't feel like it lasts that long anymore, don't lose hope. A function called Smart Battery Calibration can help reset your battery's performance and recalibrate its minimum and maximum charge so you can keep using it to its current maximum capacity.
iOS 14.5 and later includes an update where the battery health reporting system will recalibrate maximum battery capacity and peak performance capability on iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max to address inaccurate estimates of battery health reporting for some users.
Shortly after removing the file, your device's operating system will create a new, completely clean, 'batterystats.bin' that will not contain any prior information. In this way, the battery will be perfectly calibrated.
