Technical FAQs 4

Do power tool batteries need a voltmeter?

The same process works on most lithium power tool batteries with different voltages. All you need is a voltmeter to test your non-working power tool batteries to see if they can be quickly and safely restored. The Problem: Power tools are designed to stop running before their battery voltage gets too low.

How do you test a non-working power tool battery?

All you need is a voltmeter to test your non-working power tool batteries to see if they can be quickly and safely restored. The Problem: Power tools are designed to stop running before their battery voltage gets too low. However, with older batteries, the voltage will drop too low.

Why is my power tool not charging?

Power tools are designed to stop running before their battery voltage gets too low. However, with older batteries, the voltage will drop too low. When this occurs, your battery charger will indicate the battery as DEFECTIVE and will not allow you to charge it. Refer to the video for an example of a charger indicating a bad battery.

What happens if a battery is too low?

In reality, there may be nothing wrong with the battery; its voltage just dropped a little too low. With a battery in this condition, we can simply balance it with another battery. Power Tool Battery Balancing offers a quick fix for low battery levels by using one battery to recharge another.
