I fixed 20v Parkside Battery For FREE
Published at : 23 Dec 2025
In this video, I tackle a common issue with the Parkside 20V Team 4Ah battery—when it won’t charge and shows a fault light on the charger. Using a voltmeter, I discovered that the battery was only showing around 2.5V, which is far too low for a 20V battery. Low voltage like this can prevent the battery from charging properly, but there are ways to bring it back to life.
I’ll walk you through the process of raising the battery's voltage to a chargeable level, starting with the important step of checking the cell banks inside the battery. Ensuring that the cells are near equal in voltage is crucial before attempting to boost the voltage.
To safely raise the voltage, you can either jump-start the battery using another fully charged battery or, preferably, use a DC power supply to gradually bring the voltage up. In this video, I’ll demonstrate the preferred method and share tips on how to safely revive a low-voltage battery.
If you’re dealing with a similar issue, this video will provide you with the knowledge and techniques you need to get your Parkside battery back in working order.
