Quick answer
- On the Toro 60V chargers (the 81802 standard and the 81805 rapid), a blinking red LED means a battery pack charging fault. A solid red LED means the pack or charger is outside the allowed temperature range.
- Blinking green means charging, and solid green means fully charged.
- Toro's manual gives a charging range of 41°F to 104°F (5°C to 40°C). Bring the pack and charger to room temperature before retrying.
- Inspect the pack for swelling, a cracked housing, or terminal corrosion. Visible damage means the pack should be retired, not charged.
Symptoms
When you see a red light on your Toro Flex-Force charger, you may notice:
- LED pattern (81802 / 81805 chargers): blinking green = charging; solid green = fully charged; solid red = too hot or too cold; blinking red = battery pack charging fault. If the LED is off entirely with a battery seated, suspect the AC cord, the outlet, or the charger.
- Behavior under load: a pack that powers the tool briefly and then cuts out, even after a completed charge cycle, is usually a tired pack rather than a charger fault.
Quick checks
- Battery temperature: if the pack feels hot, let it cool before charging. If it is cold, bring it to room temperature. Charging works between 41°F and 104°F.
- Battery connection: remove and reinsert the battery to make sure it is seated. A loose connection can stop charging.
- Charger condition: inspect the charger for damage. A faulty charger can look like a bad battery.
- Terminals: check the pack terminals for dirt or corrosion and clean them gently with a soft, dry cloth.
- Compatibility: confirm you are using the correct Toro charger for your 60V Flex-Force battery.
Step-by-step fix
- Remove the battery from the tool so it cannot start by accident.
- Inspect the battery. If you see swelling or corrosion, do not use it. Recycle it properly.
- Check the charger. If you have a second Toro 60V charger, test the pack on it. The standard charger is the 2-amp 81802, and the rapid one is the 81805. This separates a charger defect from a battery defect.
- Test the battery voltage. With a multimeter, a pack reading far below its rated voltage may have failed.
- Reinsert and charge. Watch the LED. If it still shows blinking red after the pack is at room temperature, the battery may need replacing.

If it still isn't working
- Warranty service: if your battery is under warranty, contact Toro customer service about a replacement or repair.
- Authorized service center: if it is out of warranty, find a Toro service dealer for professional diagnosis.
- Replacement: if repair is not practical, a new battery may be the best option.

The LED meanings and the charging temperature range come from Toro's 60V charger operator's manual, which covers the 81802 and 81805 chargers. Check the manual that came with your charger if it is a different model.
FAQ
What does a flashing red light mean on my Toro charger?
On the 81802 and 81805, blinking red is a battery pack charging fault, and solid red is a temperature problem. Solid red usually clears once the pack is back in range.
Can I charge my Toro battery in cold weather?
Toro's manual gives a charging range of 41°F to 104°F (5°C to 40°C). Warm a cold pack to room temperature first.
How can I tell if my charger is faulty?
Inspect it for visible damage and try a different compatible battery. If it fails to charge several batteries you know are good, it may be defective.
What should I do if my battery is swollen?
Do not use or charge a swollen pack. Call2Recycle bins at Home Depot and Lowe's explicitly do not accept damaged, defective, or swollen lithium-ion cells — take a swollen battery to your local household hazardous waste (HHW) facility instead, or follow Call2Recycle's damaged/defective/recalled (DDR) procedure. Until then, store it in a non-combustible container away from other batteries and flammable materials.
Is there a way to revive a dead battery?
If the battery is not responding, work through the steps above. If those fail, replacement is the safer option.
