Quick answer
On an EGO CH5500, a steady red LED 1 means the battery is too hot or too cold, and charging starts on its own once it is back in range. A flashing red LED 1, or all LEDs off, means defective: the battery pack or the charger. The CH7000 uses the same logic on its middle LED (LED 3). Do not read steady red as a pack fault.
Try our charger light-code decoder for these patterns. Everything below comes from EGO's CH5500 and CH7000 manuals.
LED code decoder: EGO CH5500 (four LEDs)
| LED state | What it means (EGO's manual) | Action |
|---|---|---|
| All four LEDs shine green briefly on plug-in | The charger is working correctly (self-check) | Nothing needed |
| LED 1 shining red, LEDs 2-4 off | The battery is too cold or too hot; charging begins when it returns to 37°F (3°C) to 135°F (57°C) | Allow the pack to reach a normal temperature. Charging begins automatically |
| LED 1 flashing red, or all LEDs off | Defective: the battery pack or charger is defective, or there is a bad connection | Follow the steps below |
| LED 1 flashing green, then LEDs shine green in sequence | Charging; the LEDs show under 25%, 25-50%, 50-75% and 75-90% | Wait; the fan runs continuously while charging |
| All four LEDs steady green | Fully charged (90-100%); maintenance charging | Wait until the fan stops, remove the pack and unplug the charger |
| Intermittent quick green flashing | Self-maintenance (sleep) mode; a pack left on the charger for a month or more drops to about 30% | Reinstall the pack on the charger to recharge it fully |

LED code decoder: EGO CH7000 (five LEDs)
The CH7000 has four green LEDs and one red/green LED in the middle (LED 3), all part of one ring.
| LED state | What it means (EGO's manual) | Action |
|---|---|---|
| All five LEDs shine green briefly, then go out, on plug-in | The charger is working correctly (self-inspection). If no LEDs light green on plug-in, the charger may be defective | See the manual's troubleshooting |
| LED 3 shining red, other LEDs off | The battery is too cold or too hot; charging begins when it returns to 37°F (3°C) to 135°F (57°C) | Allow the pack to reach a normal temperature |
| LED 3 flashing red, or all LEDs off | Defective: the battery pack or the charger | Follow the steps below |
| LED 1 flashing green, then the LEDs shine green clockwise | Charging; the five LEDs show under 15%, 15-35%, 35-55%, 55-75% and 75% or more | Wait; the fan stops when charging is complete |
| All five LEDs steady green | Fully charged (90-100%); maintenance charging | Wait until the fan stops, remove the pack and unplug |

Flashing red or all LEDs off
EGO's steps for the defective indication:
- Remove the battery pack and reinsert it.
- If it still shows defective, try a different pack.
- If the other pack charges, dispose of the defective one.
- If the other pack also shows defective, unplug the charger, wait until the flashing LED goes out, and reconnect. If it still shows defective, the charger may be defective.
Charging temperature
Both manuals give the recommended ambient charging temperature as 41°F to 104°F (5°C to 40°C). The charger starts when the pack itself is between 37°F (3°C) and 135°F (57°C). A steady red LED means the pack is outside that range, and the manual says to let it reach a normal temperature, after which charging begins automatically.
No LEDs at all
The manuals count all LEDs off as a defective indication, so use the steps above. Before that, check the outlet.
Leaving a pack on the charger
When all LEDs are steady green the pack is full and in maintenance charging. EGO's manual says to wait until the fan stops, then remove the pack and unplug the charger. A pack that stays on the charger for one month or more drops to about 30%, which is the self-maintenance (sleep) mode described above.
If it still isn't working
Read EGO's current warranty terms for your pack and charger. The CH5500 manual lists a 3-year limited warranty on battery packs and chargers for personal, household use. If a pack is swollen, cracked or leaking, stop using it.

FAQ
What does a flashing red light mean on my EGO charger?
On the CH5500, LED 1 flashing red, or all LEDs off, means defective: the battery pack or the charger. On the CH7000 the same applies to LED 3. Remove and reinsert the pack, then try a different pack.
What does a steady red light mean on my EGO charger?
The battery is too cold or too hot. Charging begins when it returns to 37°F (3°C) to 135°F (57°C). Allow the pack to reach a normal temperature.
Why won't my EGO battery charge in the cold?
Steady red means the pack is outside 37°F to 135°F. Let it warm and charging begins on its own. EGO recommends charging in an ambient temperature of 41°F to 104°F.
How do I know when my EGO battery is full?
On the CH5500, all four LEDs are steady green; on the CH7000, all five are. EGO says to wait until the fan stops, then remove the pack and unplug the charger.
What is the sleep mode?
Intermittent quick green flashing means self-maintenance mode: a pack that stays on the charger for a month or more drops to about 30%. Reinstall the pack on the charger to recharge it.
