If you know how to check a battery, go ahead, but if you don’t, then here are the steps that you have to follow to check your battery-

Check The Voltage

Use a voltmeter or multimeter to check the voltage of your battery. Make sure the voltage of the battery is between 12.4 and 12.7 volts.

Inspect The Battery

Inspect your battery and its terminals thoroughly for any corrosion and leaking. Sometimes, corrosion or leaking causes the battery to not receive the current from the charger.

Check The Expiry Date

Sometimes, the battery gets expired, and we don’t know it, so make sure to check the battery’s expiry date. If the print on the battery has faded, then search about your battery on the internet. You’ll get to know about its expiry date there.

So these were the basic things you have to do before begining to diagnose your Schumacher battery charger.

How To Troubleshoot A Schumacher Battery Charger (Problems And Solutions)

Following are the most common Schumacher battery charger problems with their solution-

The Charger Doesn’t Recognize The Battery

SOLUTIONIf your Schumacher battery charger doesn’t recognize the battery while connected with it, it means that there’s a problem with the battery. The charger starts recognizing the battery when the battery reaches at least 4 volts.

So if the battery charger can’t recognize the battery, it means the battery is deeply discharged.

The Charger Won’t Turn On When Connected

SOLUTION– If you’ve properly connected your Schumacher battery charger to the power outlet, but the battery won’t turn on, it means there can be an issue with the power outlet.

Connect the charger to any other power outlet or connect any other appliance such as a stand fan or a portable cooler to the power outlet to ensure if the problem is with the power outlet. If the other appliances work, then jiggle and pat lightly on the charger’s sides and connect it again. If the charger still doesn’t work, it means it needs a repair.

The Charger Blinks A Yellow Light

SOLUTIONIf your Schumacher battery charger blinks yellow light when connected to the battery, it means that your battery is in ‘Abort mode’, which keeps the battery from finishing its charge.

Now, in this case, unplug and replug the charger 4-5 times. Your problem will be solved.

The Charger Clicks On And Off

SOLUTIONA Schumacher battery charger is equipped with a protective mechanism that allows it to turn off if the battery overheats.

So if your battery is overheating, let it cool down and then connect the charger to it again. If the charger still clicks on and off, shut off the charger and reverse the battery connections.

If your problem is still unresolved, the issue is with the battery charger, and it needs to be repaired or replaced.

The Charger Makes Clicking Noises

SOLUTIONIf your Schumacher battery charger makes a clicking noise while charging the battery, it means either the battery has some problems, or the connections are week.

Now, in this case, take a thorough look at the connections and ensure that they are intact. If the clicking sound is still emitting, let the charger run for at least 20 minutes because sometimes the battery is very discharged, and it takes some time to get recognized by the battery.

If you still hear the clicking sound, the problem is with the battery, and you need to replace it.

The Battery Won’t Charge When The Charger Is Connected And Turned On

SOLUTIONSo, if you find that your battery isn’t charging when connected to the charger. Here are the things you have to follow-

  • Recheck the connection and jiggle and rock the clips back and forth to ensure that the connections are established well. Now, reconnect the charger and check if it’s working or not. If the problem is still not resolved, go for the next tip.
  • Connect the charger to a different battery. If you find the charger is working and the battery is charging, the problem is with the original battery. If the new battery you connected with the charger is also not charging, it means the charger is malfunctioning.

So this was about how to troubleshoot a Schumacher battery charger. Next, you’ll learn how to use a Schumacher battery charger correctly.

How To Use The Schumacher Battery Charger Correctly

Here are some essential guidelines that you should follow to prevent your Schumacher battery charger from the common problems-

Right Charging Place

Always charge your battery at a well-ventilated place. Charging your battery at a warm or non-ventilated place can cause the battery to overheat faster, and that may affect both your battery and Schumacher battery charger.

Using The Right Charging Mode

Different types of batteries such as AGM, lithium-ion, gel cell, flooded use different technologies, and it’s essential for you to know about the technology and charging mode your battery uses.

Charging the battery with the right charging mode helps the battery run for longer and prevents any kind of damage.

The Float mode, also known as the maintain mode, is a type of automatic charging that uses cycles to keep the batteries from overcharging.

The Float mode is the best mode to use to charge a battery, but still, it’s essential to know about the exact charging mode you’re recommended to use for your battery.

Using Correct Voltage To Charge

Some Schumacher battery chargers are equipped with both 6 V and 12 V load modes. So if you need to charge a 12 V battery, then ensure to switch your charger to 12 V and if you need to charge a 6 V battery, then switch it to 6 V.

Don’t charge a 12 V battery at 6 V or a 6 V battery at 12 V because it’s an incorrect voltage regulation that can cause severe damage to both the battery and charger.

So this was about how to use your Schumacher battery charger the right way.

Conclusion

The Schumacher battery chargers are among the best battery chargers in the world. If you have a Schumacher battery charger and it doesn’t work, you need to know the possible causes and try troubleshooting it yourself before replacing it.
