When to Replace Your Power Tool Battery

Power tool batteries naturally degrade over time. You may notice it’s time for a replacement if:

• Your battery drains much faster than it used to

• The tool’s performance is inconsistent or underpowered

Jupio's high-quality replacement battery for Festool gives your tools a second life – without the premium price tag of OEM parts.

Why Keep a Spare Battery on Hand?

Having a backup battery is a must in the following situations:
