What Does The Red Light On A Bosch Battery Charger Mean?
Whether you're a DIY enthusiast or a professional contractor, Bosch's reliable battery-powered tools are built to last. You still have to properly maintain them, which means understanding the signals your Bosch battery charger may send. This is especially true of the alarming red light.
A continuous red light on your Bosch battery charger means the battery is likely too hot, putting it out of charging range. If this happens, don't toss the battery and rush out to buy a new one, as the red light doesn't necessarily mean the battery is shot. You can instead remove the battery and wait until the temperature drops to anywhere between 0 and 45 degrees Celsius, or 113 degrees Fahrenheit.
If the red light is flashing at the same time the green light is on while you're charging, then there's something internally wrong with the charger. In this case, make sure the battery is in correctly, then unplug the charger and plug it back in. If you get the same blinking red light at that point, it's best to have the charger checked out by an authorized Bosch technician.
You can troubleshoot any problems with your Bosch battery charger before buying a new one
The indicator light on a Bosch battery charger will let you know exactly what's happening with the device and if it's flashing green, the battery's charged and you're good to go. If you're not getting a green light or a red light, then it may be due to user error.
This means that when plugging in the charger, you need to be sure it's all the way into the socket. Also, double-check the battery itself to confirm it's correctly placed into the charger. If the battery or charger contacts are dirty, clean them and try again. Until you troubleshoot the problem, the battery charger will likely not work and you'll be unable to power your affordable Bosch power tools.
It may not be anything you've done wrong, as there's also a chance your device cable or the battery charger is defective. If that's the case, you're probably looking at a replacement. If you do have to buy a new battery or charger, be sure to recycle your old lithium-ion batteries in an environmentally safe way instead of tossing them in the trash.
