Frequently Ask Questions (FAQs)

How Do I Know If My Traxxas Battery Is Charging?

There are a few things that you can do in order to tell if your Traxxas battery is charging. First, you’ll want to check the light on the charger. If the light is green, then this means that the charger is working and that your battery is charging.

You can also check the voltage of your battery with a voltmeter. If the voltage is increasing, then this means that your battery is indeed charging. Finally, you can test the charge of your battery by using it in an RC vehicle or device.

If it powers on and works properly, then this means that your battery is charged and ready to go!

Why is My Battery Charger Not Charging My Battery? 

If your battery charger is not charging your battery, there are a few possible reasons. First, check to make sure that the charger is properly plugged into an outlet and that the power cord is firmly connected to the charger. If the charger is plugged in but still not working, try using a different outlet.

It’s also possible that the charger itself is defective and needs to be replaced. Another possibility is that the battery itself is damaged or old and needs to be replaced. If you’ve been using the same battery for a long time, it may no longer hold a charge as well as it used to.

Batteries typically last for about 500 charge cycles before they need to be replaced. Try testing your battery with a voltmeter to see if it’s still good; if not, it’s time for a new one. Finally, make sure that you’re using the right type of charger for your battery.

Some chargers are only compatible with certain types of batteries. For example, NiMH (nickel-metal hydride) batteries can’t be charged with Li-ion (lithium ion) chargers. If you’re not sure what kind of charger you need, consult the owner’s manual for your device or contact the manufacturer directly.

What Does Red Blinking Light on Traxxas Charger Mean? 

If you see a red blinking light on your Traxxas charger, it means that the charger is not properly connected to the battery. Make sure that the charging leads are correctly plugged into the charger and the battery. Also, check that the polarity of the connection is correct.

Why is My Traxxas Ez-Peak Not Charging?

If you own a Traxxas Ez-Peak charger, you may have noticed that it sometimes doesn’t seem to charge your batteries correctly. There are a few reasons why this may be happening. The first reason is that the charger may not be getting enough power from the outlet you’re using. 

Make sure that you’re using an outlet that can provide enough power for the charger. If you’re not sure, try plugging it into a different outlet. Another reason why your Traxxas Ez-Peak may not be charging correctly is because the batteries you’re using are low quality. 

Batteries can vary greatly in quality, even if they appear to be the same size and type. If you’re having trouble with your charger, try using different batteries. Finally, it’s possible that there is something wrong with the charger itself. 

If you’ve tried all of the above and your charger still isn’t working correctly, contact Traxxas customer service for assistance.

How to Tell If Traxxas Battery is Bad?

One of the most popular questions we get here at RC Geeks is how to tell if a Traxxas battery is bad. There are a few things you can look for to help determine if your battery needs to be replaced. Here are some tips: 

If your battery is more than 3 years old, it’s probably time for a replacement. Traxxas batteries have a lifespan of around 300-500 cycles, so if you’ve been using your RC regularly, chances are your battery is nearing the end of its life. If your battery isn’t holding a charge like it used to, or if it takes longer to charge than normal, this is another sign that it’s time for a new one. 

If you notice any swelling or bulging on the battery pack, this is an indication that the cells inside are damaged and need to be replaced. Swelling can also cause the battery case to crack, so be sure to check for this as well. If you see any leaking from the battery pack, this means that the cells inside are damaged and need to be replaced immediately.

Leaking can also cause damage to other parts of your RC, so be sure to clean up any leakage right away. Hopefully these tips will help you determine whether or not your Traxxas battery needs to be replaced.
