Safety Precautions

High Voltage can kill you.  High Voltage DC is especially dangerous.  Do not attempt to work on hybrid vehicle batteries unless you are properly trained.

Do not use if you are unsure of how to safely disassemble, repair, and reassemble high voltage battery pack assemblies.

Wear proper safety equipment, including high voltage gloves and eye protection at all times.

Do not attempt to operate the system on less than the minimum AC power required for the ProlongPro Charger.

Use at your own risk.  Hybrid Automotive LLC will not be held liable for improper use resulting from inadequate user training, installation, connection, or insufficient safety precautions. Return to top

Battery Reconditioning Process Overview

NiMh Hybrid electric vehicle battery reconditioning consists of two primary elements: (1) charging/cell balancing the battery pack and (2) deep discharging the battery pack to progressively lower voltage levels.  Battery reconditioning is combining the charging/cell balancing process and deep discharging process multiple times to recondition the battery.  This combined process will break down voltage depression (memory effect) within the battery cells and equalize the cell voltage levels with each other.  The ending result is a battery with more usable capacity for the vehicle to take advantage ofReturn to top

Preventative Maintenance Reconditioning Process Detail

Note: While not required, we recommend disconnecting the 12V AUX battery to ensure it is not accidentally discharged by interior lights while performing the reconditioning process.

1) Install the Prolong Car Harness onto the battery pack, being sure to connect it to the hybrid battery cooling fan.  Refer here for car harness installation instructions.

2) Charge the battery using the 'Charge & balance' setting.  Select a Cell Balancing Time of at least '1 hour'.

3) Discharge the battery to at least 0.8V per cell average.  For example, on a Prius battery pack that has 168 cells, the Discharge Termination Voltage selected would be 134 Volts.  (Refer to this table for pack level voltage termination points.)

4) Charge the battery using the 'Charge & balance' setting.  Select a Cell Balancing Time of at least '1 hour'.

5) Discharge the battery to at least 0.5V per cell average.  For example, on a Prius battery pack that has 168 cells, the Discharge Termination Voltage selected would be 84 Volts.

6) Charge the battery using the 'Charge & balance' setting.  Select a Cell Balancing Time of at least '1 hour'.

7) Discharge the battery to at least 0.3V per cell average.  For example, on a Prius battery pack that has 168 cells, the Discharge Termination Voltage selected would be 50 Volts.

8) Charge the battery using the 'Charge & balance' setting.  Select a Cell Balancing Time of at least '4 hours'.

9) Disconnect the charger and allow the battery to rest for at least one hour before attempting to start the vehicle.

The above process constitutes one battery reconditioning treatment. Return to top

‘Failed’ Battery Repair & Reconditioning Process Detail

1) Remove the battery pack from the vehicle.  The car harness installation instructions located here can be used as a guide for hybrid battery removal.

2) Remove the battery pack buss bars to isolate each module/stick for testing.

3) Using the ProlongPro Battery Discharger module testing process, identify failed modules and remove them from the battery pack.

4) Replace failed modules with good tested quality replacement modules.  We can refer you to a trusted supplier of tested used modules.  Contact us for more information.

5) Reassemble the battery pack and install it into the vehicle along with a Prolong Car Harness, being sure to connect it to the hybrid battery cooling fan.  Refer here for car harness installation instructions.

Note: While not required, we recommend disconnecting the 12V AUX battery to ensure it is not accidentally discharged by interior lights while performing the reconditioning process.

6) Charge the battery using the 'Charge & balance' setting.  Select a Cell Balancing Time of at least '1 hour'.

7) Discharge the battery to at least 0.8V per cell average.  For example, on a Prius battery pack that has 168 cells, the Discharge Termination Voltage selected would be 134 Volts.  (Refer to this table for pack level voltage termination points.)

Errors (Charger)

The ProlongPro Charger System has several safety mechanisms to protect itself and a connected hybrid battery against damage.  Below is a summary of each fault with details on what causes the fault condition to occur. Return to top

Error: Polarity Reversed or No Battery Connected (E1)

This error will be displayed when no battery is connected, or if the battery connection polarity is reversed when starting a charge cycle.

If this error is displayed and the voltage display reads zero volts, then recheck the Prolong Car Harness connections, car harness fuse, or ProlongPro Charger internal fuse. 

If this error is displayed and the voltage display reads negative volts, the battery connection polarity is reversed.  Recheck the Prolong Car Harness connections against the installation instructions located here Return to top

Error: Inadequate Voltage Increase Detected (E2)

While charging at peak current of around 3.25A battery voltage should always be rising. While the charge current is above 3.2A, if battery voltage stops rising for more than four minutes the system will shut down and alert the user to error E2. This fault is to protect against possible battery over temperature event.  

If encountered, check hybrid battery temperature.  If battery temperature is cool, restart the charge while closely monitoring battery voltage and temperature. Return to top

Error: Battery Voltage Decrease Detected (E3)

While current is between 3.2A and 500mA, voltage should be stable or rising slowly.  If battery voltage decreases by more than 500mV while current is between 3.2A and 500mA, the system will shut down and alert the user to error E3. Once the voltage reaches the taper threshold, the voltage will stabilize and hold nearly steady while the current decreases.  While voltage will not climb in this phase of charging, a decrease in voltage could be a potential sign of battery over temperature event.

If encountered, check hybrid battery temperature.  If battery temperature is cool, restart the charge while closely monitoring battery voltage and temperature. Return to top

Error: Battery Voltage Decrease Detected (E4)

While current is below 500mA, the battery is top charging/cell balancing and slow oscillation of pack voltage is normal.  However, if the battery is not being sufficiently cooled, it may become warm and voltage may decrease beyond acceptable limits.  If battery voltage decreases by more than 5V during top balancing, the system will shut down and alert the user to error E4.  

If encountered, check hybrid battery temperature.  If battery temperature is cool, restart the charge while closely monitoring battery voltage and temperature. Return to top

Error: Charger Over Temperature (E5)

The ProlongPro Discharger has internal temperature monitoring.  If the discharger internal temperature rises above this safety threshold, the system will abort the process, revert to idle, and alert the user to error E5.

If encountered, check charger temperature.  Verify both charger cooling fans are running and free of obstruction.  Cool the charger system by leaving it powered on in an idle state for 10-15 minutes.  Verify ambient temperature is not above system rated maximum ambient temperature of 100 degrees Fahrenheit (38 degrees Celsius). Return to top

Select Discharge Termination Voltage

The Select Discharge Termination screen prompts the user to select how deep the battery pack will be discharged. This menu is dynamic and will change depending on the battery size (number of cells) selected.  All discharge termination values are the same when adjusted for the number of cells in the battery pack.  Said another way; while the discharge termination values vary due to the differing cells counts contained in each battery pack configuration, they are the same when considered on an individual cell level. 

In order for the voltage depression memory effect to experience any reversal, the cell must be drained to AT LEAST 0.8 volts.  Discharging a cell to a termination value above 0.8 volts will not result in any voltage depression reversal. 

The four discharge termination values are 0.8 volts per cell average, 0.5 volts per cell average, 0.3 volts per cell average, and 0.1 volts per cell average.  Multiplying these cell level average values with the number of cells within a battery pack will result in the values shown on the system LCD screen.

For example, a 2007 Prius battery pack has 168 cells.  The four available discharge termination voltages displayed by the system for a 04-15 Prius are 134 volts, 84 volts, 50 volts, and 17 volts.  Expressed mathematically, 168 cells x 0.8 volts per cell = 134 volts; 168 cells x 0.5 volts per cell = 84 volts; 168 cells x 0.3 volts per cell = 50 volts; and 168 cells x 0.1 volts per cell = 17 volts
