GEN or GENPRO isn't detecting the battery, how do I force charging to start?

NOCO GEN & GENPRO are able to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on Force Mode to detect and charge batteries all the way down to zero volts.

How to use Force Mode on GeniusPRO

Which GEN or GENPRO charger is best for my battery?

Selecting the appropriate charger for your battery will depend on its Amp-Hour (Ah) capacity size. This is usually listed on the battery label at the 20-hour rate, for example: “100 AH @ 20HR”. Check your battery for its rated Amp-hour capacity.

GEN	Up to 120 Amp-Hours
GENPRO	Up to 230 Amp-Hours

Can I run a load on the battery while charging?

It is not recommended to run a load on the batteries while they are being charged.

Charge Modes

How do I change modes on GEN & GENPRO?

When plugged into AC power for the first time NOCO GEN & GENPRO will start out in Standby Mode. Press the Mode Button to switch between modes.

What is Repair Mode on GEN & GENPRO?

Repair Mode is an advanced battery recovery mode for repairing and storing, old, idle, damaged, stratified or sulfated batteries. Not all batteries can be recovered. Batteries tend to become damaged if kept at a low charge and/or never given the opportunity to receive a full charge. The most common battery problems are battery sulfation and stratification. Both battery sulfation and stratification will artificially raise the open circuit voltage of the battery, causing the battery to appear fully charged, while providing low capacity. Use 12V Repair in attempt to reverse these problems. For optimal results, take the 12-volt battery through a full charge cycle, bringing the battery to full charge, before using this mode. 12V Repair can take up to four (4) hours to complete the recovery process and will return to Standby when completed.

Using Repair Mode on GEN & GENPRO

CAUTION: USE THIS MODE WITH CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. THIS MODE USES A HIGH CHARGING VOLTAGE AND MAY CAUSE SOME WATER LOSS IN WET (FLOODED) CELL BATTERIES. BE ADVISED, SOME BATTERIES AND ELECTRONICS MAY BE SENSITIVE TO HIGH CHARGING VOLTAGES. TO MINIMIZE RISKS TO ELECTRONICS, DISCONNECT THE BATTERY BEFORE USING THIS MODE.

LEDs

The green LED is flashing, is charging done?

When GeniusPRO has a slowly pulsating green LED it means the charger is in Maintenance Mode. After the battery is fully charged, the charger will continue to provide ongoing maintenance and optimization until disconnected.

What does the Overvoltage Error LED mean?

If the Overvoltage LED is illuminated, this means the battery's voltage is too high for the charge mode that is selected. For example, if you have a 12V battery and have selected a 6V charging mode selected.

All the Error LEDs are flashing. What is wrong?

If the Overvoltage, Bad Battery, and Standby LEDs are flashing together, either the charger's internal temperature is too hot, or the ambient temperature is too cold for operation. If the charger's internal temperature is too hot, the charger will stop displaying the error and resume function after the charger cools down. If the ambient temperature is too cold, the charger will resume function when the ambient temperature rises.

What does it mean when GEN & GENPRO is flashing a charge LED and Standby Mode?

If a charge LED and Standby mode are flashing this means Genius is in Force Mode. After 5 minutes, the charger will return to the normal charge mode operating and low voltage detection will be reactivated.

When in Force Mode all safety features will be disabled.

My GEN or GENPRO charger is stuck in Standby Mode.

If the Standby LED is illuminated it means that GEN or GENPRO is in Standby Mode and it is not recognizing that it is connected to a battery. This can happen when there is no battery connected to the charger, if the voltage on the battery is lower than the recognition threshold (1V), if the connection to the battery is faulty, or if the inline fuse is faulty or loose in the fuse housing.

How to use Force Mode on GEN & GENPRO

What does the Bad Battery Error LED mean?

If the Bad Battery Error LED is illuminated, this means that the battery is not holding a charge, or there may be a short in the battery. We recommend taking the battery into a local battery shop for a thorough evaluation of its health and status.

Does NOCO make a protective case for GEN & GENPRO?
