I reconditioned my hybrid battery - by accident

That's awesome

 

This indicates that your battery pack will be much improved once you use the prolong system. A really long drive, as well as a leaving it running for a long time will create a slight boost to pack performance, but not much compared to how much the Prolong system will change things.

 

It doesn't sound correct. Of all the times I've sat, It has never gone beyond 3 bars, or
below 2 bars. Until the end of it's life.
Take the time to install the harness for the Prolong system, It's not hard, just takes time.
And clean all the bus bars with backing soda and water. And a wire brush.
Be VERY careful with the posts on the battery packs, you can EASILY short two together!
You only want to touch ONE post at a time.

It will take 3 days to complete the full cycle. If you watch it closely and often, you can catch it
when it finishes the discharge cycle and get it on the charge cycle.
The 4th, and last charge cycle should take the longest. When the voltage full and stable, let it charge
for another 2 hours. So it will have a chance to fully charge each block, and "balance" all the blocks.
Wait 2 or 3 hours after the last charge for the battery to cool off and for the voltage to go down and
get stable.
It will be well worth it! It kept mine going to 2.5 years and about 100,000 miles.
Then I got the lithium pack, then the Sodium pack! That is well worth it!

 

2 bar minimum is fine but 1, squirrel!

 

If you ever notice a sudden drop down to one or two charge bars that then recover back to normal charge in 5 to 10 minutes, that's due to the corrosion in the bus bars working their way into the battery ECU via voltage sensor wires. So if that happens you'll want to open the ECU and clean it up inside there. You can also buy new higher quality voltage sensor wire harness at acenbay.com

 

I am in the process of installing a new set of NewPriusBatteries into a spare battery assembly for a Gen2 Prius - when I removed the factory harness plug for the voltage sensor wires from the ECU I noticed some green corrosion on a few of the pins in the ECU - any recommendation on a safe way to clean them off? Those pins look awfully fradgile

 

Glad you got the harness installed. The rest is easy. Even if you just charged it overnight
it will peak them out, and that will help. Those bus bars don't look bad. It's the copper that's
important, not the black coating...

 

Electrical contact cleaner spray. Spray both pieces and attach and remove the a few times.
That's the safest way. There are very small brushes designed to clean the small pins.

 

That would be much appreciated.

 

I use a tiny piece of sandpaper with a screwidriver behind it... I've also used an emory board.

Most important is to open up the inside of the ECU and clean the corrosion off the other ends of those pins where they connect to the circuit board.

 

The hv bat stops charging at 60% and begin charging At 40% with I.c.e. 99% of the time even as it idled then a lot of prolong charging people are pounding the sand w both fists.

 

• The hybrid battery (HV battery) typically operates in a range of 40%-80% state of charge (SOC) to optimize battery life and performance.
• The internal combustion engine (ICE) or regenerative braking charges the HV battery when the SOC drops below approximately 40%.
• Charging usually slows or stops when the SOC reaches around 60%-70% during normal driving conditions. However, the car may let the SOC rise higher (up to ~80%) under certain conditions, like long downhill drives.

So, while 60% and 40% are within the expected operating range, the system is more dynamic, and exact thresholds can vary slightly depending on driving conditions.

 

Maybe 60% is when all but the top two pips are lit (usual peak charge), and 80% is when those two top pips light (say on an extra long downhill).

 

• "Usual Peak Charge" (60%): This corresponds to when all but the top two pips are lit on the battery display. It reflects the target range the system tries to maintain during normal driving for efficiency and longevity.
  
  
• "80% SOC on Long Downhills": This occurs when the top two pips light up, which is rare and typically happens during extended regenerative braking (like on long downhill stretches). This reflects the system temporarily storing more energy.
  

In summary, the battery display provides a simplified representation of SOC. The top two pips lighting up doesn't mean the battery is fully charged; it indicates it's nearing the upper end of its operating range (about 80%).

 

You bought the reconditioner hv battery kit for the original nimh battery pack, and your now on a second battery pack but yet it was worth it? Definitely doesn’t compute.

 

OPster hv battery went thru that process so for sure his hv bat didn’t go through ey a reconditioning process.

 

Translated: The oem was worn out but limped on with or without the Prolong. Then the aftermarket lithium pack was great (as seen on Priuschat) until it was not. It was replaced two or three years later with another experiment that may or may not work in freezing weather. Plus the experiments cost as much as a new oem that will easily run ten or more years.

 

No, you didn't read everything....

I used the Prolong system for about 2.5 years. Well worth it.
I was going to put in the battery from Toyota, all new cells. But they won't sell
it to anyone unless they are hybrid certified.
So I looked for new ones from someone else, but they were way too expensive.
So I looked for the round cylinders, again, too expensive. And I guess he had gotten
burned enough to be pissed off that he warranty basically said you get nothing unless
you follow a hundred rules..... So I said no.
That's why I decided to go with Jack and the lithium. I had no issues with ordering and
it arrived in 3 days.
I was very happy with it, and him.

It was about 4 months, not sure exactly, before Jack contacted me.

He asked me if I'd interested in testing his sodium pack, and I said yes.
I had already been researching the sodium batteries before knew he was working
with the sodium cells. So I said yes.
It's even better than the lithium. At least for me. A lot lighter and easier to lift into the car.
MPG has improved and distance is better. 104 degrees is the highest the battery has
gotten, and that is when I was trying to get it hot by sitting in the hot humid sun for half the day then
driving without letting the engine kick in. It was in the mid 90's for several months here with
super high humidity here.....

Jack has been great. Getting back with me quickly with all the questions I had.

I would recommend it for anyone who needs a new hybrid battery.
