Pack voltage is fine. Blocks 7 & 8 are starting to show their age, though. Grid charging with a Prolong or Maxx Volts might bring them back into...
I’m saying that letting it sit is very bad for the hybrid battery too. It’s a 15 year old battery. It excites corrosion at the very least. And if...
Further comments for now: * My AGM (12v) battery is definitely wayyyy weak. Will replace soon. It's original (2011)! * I'm working with Jack (Dr...
You really need Techstream and the mini VCI cable. Install it in an old laptop that doesn't connect to the internet. It will allow you to measure...
I have not actually raised the battery voltage while monitoring the Prius to see at what voltage this occurs. But have noted that at seven green...
If by replacing a bad cell, do you mean a bad module? If so, why not replace both in block 5? How did you determine which of the modules to...
According to Hybrid Automotive, the grid charger rebalances the cells. A Prolong Battery Charger is an HEV power grid charger that very slowly...
I received a brand new, in the box, Prolong Deluxe model as a partial trade for a battery job a few years ago. I used it a couple times to do some...
Prolong Charger.... But, you can use a volt meter to check the voltage. You'll have to remove the cover of the hybrid battery. All pretty simiple.
Yes, but I had a different situation and ambient conditions. You might give it some more time and see if it balances upwards again. Otherwise...
I would match pairs based on effective series resistance, not capacity. When you do the load test you will see a delta voltage drop. put...
Sure but you'd need another harness as repeatedly removing the one installed in the car would be a big PITA and the connections are not designed...
Final Fill and Balance Expediting the fill stage I had to be done by 7am, so after the Prolong charger brought the pack voltage well into the...
I have Hybrid Automotive's Prolong Deluxe Reconditioning Package. Hybrid's FAQ does not recommend using the charger for extended storage. How...
Loading prius modules with 50-100 amps to 6.5 volts is tantamount to helping the modules die. In the situation where this is your only car, I...
I have a 2010 Toyota Prius 123,000 miles on it that is occasionally showing the PA080 error. So far for my troubleshooting I have done the...
Installed the replacement Prolong Harness this morning. I measured each individual battery pack. They seem to be pretty even. Within about .015...
While it wasn't required in the Prolong instructions, I did measure each battery anyways. I'm not sure if there's a better way to measure IR, but...
Yea, lots of bad info on youtube. That guy isn't really teaching a "master's class." NiMh are not balanced properly from the method he's using,...
See me in ten years when my original OEM battery is still as good as new. ;) Gen 4 Prius Prime actually has a lot of 12-V battery protection...
