Why Does Tronic Charger Have Flashing Red Light for Battery?
So we know that the flashing red light turns on when the charger detects a battery defect, but why? What is actually defective about the battery and if it is so easy to fix this issue, why can’t the charger just fix it?
The issue is caused by a drop in voltage. A standard AA battery can be 1.2v to 1.5v. A charger may accept a certain fluctuation but if the battery drops too low, the smart chargers will think the battery is completely dead with no sign of recovery.
This can happen to batteries that run out of charge and are left inside an electronic device for several months unused. Any life in the battery will naturally fade away and as far as the charger is concerned, the battery is a dud. The reality is that the battery just needs a small jolt of power to bring it back to life. The hack in this video will show you exactly how to do it.
