Is It a Faulty Product, Low Battery, or Voltage Drop?

If an appliance is not working correctly, the issue is more often be low battery voltage or wiring, rather than the product itself.

A quick way to check is by measuring voltage at the battery and at the appliance using a multimeter.

1. Measure directly at the battery terminals.

• 12.6–12.8V: Fully charged
• 12.2V: Around 50% charge
• Below 12.0V: Battery discharged

If the battery voltage is low, the battery likely needs charging.

2. Check Voltage at the Appliance

• Measure the voltage at the appliance while it is running.
• If voltage is similar to the battery, wiring is likely fine
• If voltage is much lower than the battery, this usually indicates voltage drop

Voltage drop is often caused by:

• Undersized cables
• Long cable runs
• Loose or corroded connections
