Solutions to the most common problems why Schumacher battery charger is not charging
Over time, the Schumacher battery charger may wear out even though it is made of durable materials and components, or your Schumacher battery charger won’t charge. One of the most common problems with Schumacher battery chargers is that they fail to operate or do not seem to be charging correctly.
In this section, we’ll describe some problems you may experience with your Schumacher battery charger and how to fix them.
Problem #1: The charger doesn’t produce any power, even if it’s plugged into an outlet.
Solution: There could be a problem with the fuse or breaker on your wall socket. Try using another outlet to see if the charger starts charging your battery.
Problem #2: The battery charger won’t charge the car or has a high amp draw.
Solution: Commonly, the battery is not being charged at all. Check that there are no loose connections or other problems with your car’s electrical system before using the charger.
Problem #3: The charger takes too much time to recharge the battery.
Solution: It’s normal for Schumacher chargers to be slow compared to other models, but that doesn’t mean they should take several hours or even days to work. If you’re charging a completely dead battery, it will take longer for the charger to work.
Problem #4: The charger won’t turn on when plugged in.
Solution: The Schumacher battery charger is not working correctly, and you may need to replace your main power regulator board. Double-check that the connection is secure and that your battery has enough charge before replacing a part.
Problem #5: Notice a clicking sound while charging.
Solution: These sounds happen when using a Schumacher battery charger. If you hear the clicking, it’s normal. This shows that it’s working properly and might not be an issue. Allow the device up to 20 minutes before taking any action, depending on what type of noise persists, but if the sounds continue with new batteries, there may be something wrong with your connections.
Problem #6: A yellow light blinks on the Schumacher battery charger.
Solution: You’ll know your battery is in abort mode if you see a yellow light blinking on and off. This means that the battery can’t finish charging, so it’ll be stuck at this stage until you unplug it. Wait for a while, then plug back in again to start over with another charge cycle.
Problem #7: The charger failed to recognize a battery or allow for a full charge.
Solution: This may be caused by an issue with the power board. It could need replacing, but first, you should check your wiring to make sure everything is in place and secure.
Best Practices When Using a Schumacher Battery Charger
- For a more efficient and less troublesome charge, find the right place for the plug; not too cold or too hot, as it may cause overheating or voltage drop.
- Understand the charging mode for different battery types. The ‘trickle charge’ mode is great for maintaining a battery since it’s less harmful. You may want to use the ‘float charge’ option to enhance your vehicle’s performance.
- Know the perfect match of voltage charger for your battery. In most cases, a 12V battery will work best for automobiles and smaller appliances, primarily six volts.
