How do I do a battery and charger check on my 108V Cordless Lawnmower

Created by Chris McHale, Modified on Tue, 30 Jun at 10:15 AM by Chris McHale

Quick Answer

If your 108V cordless lawnmower is not operating correctly, first check that the battery is fully charged and the charger is functioning correctly. The battery and charger both feature LED indicators that show the charging status, remaining battery capacity, and any faults.

Tip: Charge the battery fully before first use and recharge it as soon as the battery indicator shows a low charge.


Before You Start

Before checking the battery and charger:

  • Switch the lawnmower off
  • Remove the battery pack from the mower
  • Inspect the battery and charger for any visible damage

Important: Only use the charger supplied with or recommended for your 108V cordless lawnmower.


Charging the Battery Pack

Follow these steps to charge the battery correctly.

1. Connect the charger

Plug the charger into a suitable mains power supply.

The red LED on the charger will illuminate to indicate that power is connected.

2. Insert the battery

Align the grooves on the battery pack with the raised ribs inside the charger.

Press the battery down firmly until it is fully seated.

The battery handle can be lifted to make it easier to carry and position.

3. Check the charging indicators

During normal charging:

  • The red LED on the charger remains on
  • The green LED on the charger flashes continuously

When charging is complete:

  • The red LED remains on
  • The green LED stays on continuously

This indicates the battery is fully charged and ready for use.


4. If the red LED flashes

A flashing red LED on the charger may indicate:

  • A poor connection between the charger and battery
  • A problem with the charger cable
  • A fault with the battery pack

First, remove and reinstall the battery to ensure it is correctly seated.

If the problem continues and your machine is within warranty, please contact our customer service team via Live Chat or submit a support ticket.


How to Check the Battery Charge

The battery includes a built-in power indicator.

Press the battery indicator button to display the remaining charge.

The green LEDs show the current battery level.

Understanding the Battery Indicators

The battery LEDs provide information about the battery's condition.

IndicatorMeaning
Green LEDs illuminatedRemaining battery charge
Red LED flashingBattery charge is very low (below 1%)
Red LED flashing after heavy useBattery temperature is too high
Red LED flashing continuouslyBattery fault detected

If the battery becomes too hot, allow it to cool for 10–20 minutes before charging or using it again.


Lithium-Ion Battery Information

Your 108V cordless lawnmower uses a lithium-ion battery.

Unlike older battery technologies:

  • Power remains consistent throughout the discharge cycle
  • Performance does not gradually decrease during use
  • The battery should be recharged once the red LED begins flashing

Important: Do not continue using the lawnmower when the battery indicator shows a very low charge.


If the Battery or Charger Still Isn't Working

If the battery will not charge or the charger indicators show a fault:

  • Check all charger connections
  • Remove and reinstall the battery
  • Allow an overheated battery to cool before charging
  • Contact our customer service team if the fault persists

If your machine is within its warranty period, we can advise on repair or replacement options.


Important Battery Care Tips

  • Fully charge the battery before first use
  • Use only the approved charger
  • Do not store the battery fully discharged
  • Allow hot batteries to cool before charging
  • Store the battery in a cool, dry location

Frequently Asked Questions

How do I know when my battery is fully charged?

When charging is complete, both the red and green LEDs on the charger remain illuminated continuously.

Why is the red light flashing on my charger?

A flashing red LED usually indicates a poor battery connection or a battery fault. Remove and reinstall the battery, then try charging again.

Why is the red light flashing on my battery?

The battery may have a very low charge, be too hot, or have developed a fault. Allow the battery to cool if necessary, then recharge it.

Should I continue using the mower when the battery is low?

No. Recharge the battery as soon as the red LED begins flashing.

Why doesn't the mower gradually lose power?

Lithium-ion batteries provide consistent performance until they are nearly empty. Once the battery reaches a very low charge level, it should be recharged.
