USB Safety Tester J7-t — useless? or help identify a dying battery?
During this time, the apparatus helped out more than one hundred times, and sometimes even allowed me to do without bulky, not very convenient, additional measuring and charging equipment: on the back there are some important characteristics of the device And now the time has come, the old battery began to breathe heavily. I take measurements with a USB tester of the old and new (after rework) batteries in the smartphone, then I remove both batteries from the smartphone and after several charge / discharge cycles using Imax- B6, I measure the capacity several times with it when charging and discharging. Using a USB tester, I filmed the process of charging a dying stock battery with a capacity of 3600mAh (trusting the labeling and my measurement by another tester mentioned in the last article): The test subject will be the same “HEXUNBABA”, the photo report “before” and “after” is under the cut. You draw conclusions in the comments what the USB tester actually showed, why https://jiji.co.tz/17-led-tvs/black the Imax-B6 showed something different and how you can now live with it calmly or not. In this post, I will by no means review the USB tester itself (God forbid, this stuff is full on the network), but in practice, with its help and with the help of Imax B6, I will try to decide whether its readings are enough, namely along the 5V line and converted into a capacity for a charge or direct measurement from a battery bank for a discharge — is it inevitable and always mandatory? and in general I’ll try to decide whether this device has a place to be, or is its use even in domestic conditions completely unacceptable? But I had the imprudence to print a post on replacing the battery and even give a subjective assessment of the quality of the latter, relying only on the testimony of this USB tester … and the experts came to the comments — “scold me”)
