The Vax ONEPWR is a versatile removable battery pack designed to work with various cordless vacuum cleaners. I personally use the Vax ONEPWR Blade 4 cordless vacuum, which delivers approximately 80 minutes of runtime on a single charge.
However, I encountered an issue recently when my VAX ONEPWR battery began flashing red and refused to power on. Troubled by this, I promptly detached the battery pack from the vacuum cleaner and connected it to the charger, hoping for a solution. Unfortunately, there was no indication of charging taking place.
In my quest for a resolution, I reached out to the Vax customer support team, who graciously provided me with several troubleshooting methods to address the charging problem with my Vax ONEPWR lithium-ion battery. I will now share these troubleshooting steps with you, and if followed correctly, they should successfully revive the charging functionality of your battery pack.
Why is My Vax ONEPWR Battery Not Charging?
There could be various factors contributing to the inability of your Vax OnePWR battery to charge. Potential causes may include a malfunctioning charging station, a fully drained battery, a faulty wall outlet, or defective battery cells. It’s worth noting that the lifespan of OnePWR lithium-ion batteries typically spans around 400 charge cycles, translating to approximately 1.5 to 2 years of usage.
If your battery pack is relatively new, there are a few simple solutions you can try to resolve the charging issue. By following these troubleshooting steps, you can potentially rectify the problem and restore the charging functionality of your Vax OnePWR battery.
How To Fix Vax OnePWR Battery Not Charging?
I successfully resolved the charging problem with my Vax OnePWR Lithium-Ion Battery by implementing the following steps:
Step #1– To troubleshoot the charging problem with my Vax OnePWR Lithium-Ion Battery, I followed a step-by-step approach. First, I utilized a multimeter by adjusting the knob to 20V DC. Then, I proceeded to connect the black wire of the multimeter to the right side pin of the battery pack. Next, I carefully touched the red wire of the multimeter to each of the other pins individually, observing any voltage reading.
This allowed me to identify the positive and negative terminals of the battery pack. For a visual guide on recognizing the positive and negative terminals of any battery pack, I found a helpful video tutorial.
Step #2– After identifying the positive and negative terminals of the Vax OnePWR battery pack, I proceeded to jump-start it using another fully charged battery. To accomplish this, I obtained a speaker wire and connected the negative terminal of the good battery to the negative terminal of the faulty battery. Then, I connected the positive terminals of both batteries. I maintained this connection for a duration of 10 to 12 seconds, allowing the energy to flow and reset the Vax OnePWR battery pack.
Step #3–
After disconnecting the wires, I promptly placed my Vax OnePWR battery pack back onto the battery charger. In the majority of cases, as long as there are no significant issues such as dead cells or faulty circuits, this solution effectively resolves the charging problem. I can attest to its success as I personally fixed the charging problem using this method.
Furthermore, I utilized the same approach with my DeWalt Li-Ion battery pack, which also resulted in it charging again. If you would like a more detailed account of the steps I followed, I highly recommend reading the guide I referenced for comprehensive instructions.
Other Methods To Fix Vax ONEPWR Battery Charging Issue?
In most cases, the issue lies with the charger and its charging pattern rather than the battery itself. To diagnose and resolve this problem, I recommend following the solutions provided below:
1- Plug and Leave
If you have disregarded the flashing red LED indicator while vacuuming the floor, it is likely that the battery has been completely drained. In such cases, it is important to allow sufficient time for the battery to charge.
To resolve this issue, connect your Vax ONEPWR vacuum to the charger and ensure it remains plugged in for a minimum of 3 hours. This extended charging duration is necessary to restore power to the battery. Please be patient and refrain from attempting to use the vacuum during this time.
By adhering to this recommendation and providing ample charging time, you should be able to successfully recharge your Vax ONEPWR battery and resume normal usage.
2- Try a new outlet
In the event that the battery fails to charge, it is crucial to inspect the functionality of the outlet. Begin by checking whether the indicator light illuminates upon plugging the charger into the outlet.
If the indicator light does not turn on, it indicates a potential issue with the outlet. In such cases, locate an alternative wall outlet and attempt to charge your Vax ONEPWR battery there instead.
By confirming that the indicator light activates when connecting the charger to a different outlet, you can determine if the initial outlet is the source of the charging problem. This troubleshooting step will help you identify whether the outlet needs to be repaired or if an alternate power source is required to successfully charge your Vax ONEPWR battery.
3- Try a new charger
If you are still unable to charge your battery, it is likely that the charger itself has become faulty. To determine if this is the case, consider trying a new charger to assess whether your OnePWR Li-ion battery pack begins charging.
By substituting the charger with a different one, you can determine if the original charger is the root cause of the charging issue. If the new charger successfully charges the battery pack, it confirms that the previous charger is indeed faulty.
Taking this step will help you identify the problem and enable you to acquire a functioning charger to effectively charge your OnePWR Li-ion battery pack.
4- Contact support
Vax ONEPWR batteries have a designated lifespan of approximately 400 charge cycles. Once this limit is reached, the batteries begin to lose their capacity, resulting in charging problems.
If you unscrew the battery pack, you will discover a configuration of five 3.7V cells, each with a capacity of 1800mAh. Should your battery encounter charging issues and it is still within the warranty period, I recommend reaching out to the customer support team for assistance with a battery replacement.
Contacting the customer support team will allow you to explore options for obtaining a new battery that will restore optimal charging performance to your Vax ONEPWR cordless vacuum cleaner.
