Code P0A80 + P3013 All Battery Cells reading good! Any thoughts?

As long as you have the harness, the Prolong equipment can be used outside of the car.

That's what I'd use if I had access to the equipment.

 

Same here. Just keep a fan blowing on the battery pack to cool it. Preferably blowing into the air ducting to get it into the right places.

 

It doesn't care.

The harness plugs the fan in to utilize it, but if it isn't there, you need to have an alternate source of air flow.

Find a large house fan and direct it on the pack .

Air flow is the key to thermal heat removal.

 

Depending on where you are at in Georgia, you might find other Prius Gen2 or gen3 owners who think the equipment is also a good idea.

I shared the equipment with 2 other members out here which also helped reduce the investment cost.

Each one of us had our own harness and this worked well for utilizing the equipment that sits on the shelf for large blocks of time.

 

This is for a Camry, which has 34 modules instead of 28, so the Prolong uses different voltages.
The problem with the Camry and the Altima is that they are relatively tough on batteries. Every Camry/Altima battery I've disassembled and tested has come up way short on capacity compared to a similar aged/mileage Prius battery, along with having much greater variances in individual capacities. Usually, there are about a dozen modules, minimum, that need to be replaced.

Since the car has been off for quite a while, it should be very easy to determine "bad" modules with only a voltmeter. Those will be around 6.3 volts or less due to self-discharge. Unfortunately, depending on the overall battery condition, there may be a lot of them, with some "not really bad", as they may have taken a few months to self discharge, compared to some that took only weeks or days.

The prolong system will not tell you which modules are low capacity. It charges/discharges all the modules in series until it reaches its voltage setpoints.

One option would be to have the cover off, (and after it has been charged) and while it's discharging, take frequent voltage readings of the 34 individual modules. Each module has 6 internal 1.2 volt cells. Whichever module has the weakest "cell" should be the first one to drop into the 6.x volt range. As the 34 modules are discharging, I would track each one that drops into the "6"es. That will give you an indication of the weakest modules (or the modules that have failing/weak internal cells).

Then, the important thing is going to be matching the replacement modules to an estimated capacity of the remaining "good" modules. If you go through this and determine how many weak modules you have, I have several dozen "good" Camry/Altima modules on the shelf that were tested/cycled in April and May.

 

Where'd ya get the Hycam from?

@vcvtrading shows a Gen2 in his profile and a 2008 Prius in his information.

But if a Hycam, your advice is true about the battery sizes being different.

 

The 4th word in post 95....and we've had earlier discussions on the forum.
don't feel bad though, we've all been there and we'll all be there again

 

Also from the first post. Unless he switched cars and I missed it.

 

After sitting for months simple voltage readings will quickly tell you what's up. Do not start the car or charge the modules. That would obscure the effects of months of self discharge. The junk will have self discharged to 6.XX volts. They cannot be recovered. Most of the modules should be in the 7.5 to 7.7 volt range. The actual voltages do not matter as much as how they compare to each other. Any module that is .2 volts or more under the rest is suspect. Any module that is sitting at 7.3 volts or less is suspect. Module voltage keeps dropping as they sit for longer. Once the as found voltages are recorded you could do the light bulb discharge. You will find the results correlate strongly with the initial voltage readings.

A quick rebuild strategy could be to replace the junk modules based on just resting voltage and then condition the pack with a Prolong charger and discharger. That would produce a better pack than most DIY rebuilds. A downside to this method is you are not actually measuring the individual modules.

 

I believe they also sell used modules trying to match mileage with you current ones.

 

@PriusCamper could You please send me more information on how to check the condition of individual cells? Thank You.
