Quick answer
- Ensure the battery is warm enough to charge; lithium-ion batteries won't charge below 32°F (0°C).
- Check the charger; a solid red light indicates a fault with the battery or charger.
- Inspect the battery terminals for dirt or corrosion that could impede charging.
- If the charger and battery are functioning properly, consider replacing the battery.
Symptoms
When your Ego battery fails to charge, you may observe the following symptoms:
- The charger LED remains solid red, indicating a fault condition.
- The battery may not respond when connected to the charger, with no lights flashing.
- If you attempt to use the battery in a tool, it may not power on, suggesting it is not holding a charge.
- You may hear no sounds from the charger, indicating it is not processing the battery correctly.
Quick checks
Before diving into deeper troubleshooting, perform these quick checks:
- Temperature Check: Ensure the battery is not cold. If it’s below 32°F (0°C), warm it up to room temperature before attempting to charge.
- Charger Inspection: Verify that the charger is plugged in and functioning. Check for any visible damage to the charger or its cord.
- Terminal Condition: Inspect the battery terminals for dirt, corrosion, or damage. Clean them gently with a dry cloth if necessary.
- Compatibility Confirmation: Ensure you are using the correct charger for your specific Ego battery model (e.g., Ego CH2100).
- Battery Reset: Sometimes, removing the battery from the charger and reinserting it can reset the connection.
Step-by-step fix
-
Remove the Battery: Always detach the battery from the charger before performing any checks or repairs to avoid electrical hazards.
-
Inspect the Charger: Check the charger for the LED pattern. For the Ego CH2100, a solid red light indicates a fault. If the charger is faulty, replace it.
-
Check Battery Temperature: If the battery is cold, allow it to warm up to room temperature. This is crucial as lithium-ion batteries have a built-in safety feature that prevents charging when too cold.
-
Clean Battery Terminals: Examine the battery terminals for dirt or corrosion. Clean them with a soft cloth to ensure a good connection. Poor contact can prevent charging.
-
Test with Another Charger: If possible, try charging the battery with a different Ego charger to rule out charger issues. If it charges, the original charger may need replacement.
-
Consider Battery Replacement: If the battery does not charge after these checks, it may be defective. Consider purchasing a replacement battery to restore functionality.

If it still isn't working
If you have followed all the steps and the battery still does not charge:
- Warranty Check: Review your warranty status. Ego batteries typically have a limited warranty, and if your battery is within that period, you may be eligible for a replacement.
- Contact Customer Service: Reach out to Ego's customer service for further assistance. They can guide you through additional troubleshooting or help with warranty claims.
- Visit a Service Center: If you prefer in-person assistance, locate an authorized Ego service center to have your battery evaluated.
