Has anyone reconditioned their old battery and how is it now?

If you decide to get into your high voltage battery pack, you might find other factors that have contributed.

Corrosion on bus bars,
Corrosion on pins of the connectors,
Loose terminals,
Leaking acid from an individual module.

If you are confident your issue is one or two modules, it may be cheaper and quicker to purchase them from experienced member here on priuschat. You won't really know until you look inside the case.

 

Not trying to take anything away from deoxit, but a little baking soda and water can indicate the presence of acid and corrosion around the modules, on connections, and on pins.

If you are re-connecting the terminals, borrow or buy a torque wrench to make sure you have at least 48 inch pounds. The 28 modules depend on good connections.

 

I've been following some of your posts, and it seems like you are very thorough and have put a lot of effort into getting the most out of your car, especially as it pertains to the hybrid system, getting the battery temperature down, etc. I would really like to see that you are properly rewarded for all your efforts. The 2 threads I'm going to point you to are not light reading, but in case you haven't come across them yet, they may be beneficial for someone like yourself who wants to learn as much as possible and is willing to do whatever it takes to get your car running right.

Hi. Generally, now (at least in Europe) the availability of decent chargers is a big problem. All recommended, which can be seen on YT are no longer produced, and new clones have prices from space.
I recommend You start by verifying the availability of equipment. If in Your area is a problem with them, in my opinion a better solution is to send all modules to someone who has the appropriate facilities to check and regenerate them properly. Later You can experiment on one charger, even a simple iMax B6, but something more is needed to rebuild the entire package... if You don't have 3-4 weeks off without a car
Chargers that will allow you to correctly assess the cells must have the option of discharging / charging at least 3A, preferably 5A.
All iMaxes have max. 1A discharge, and this is not enough to be realistic check battery status.

I drew such conclusions on my example when I started to study the topic of regeneration from scratch... but because I am also a freshman in the subject, of course I can be wrong

I have an Imax B6, and supplement it with a 20W and 50W 12V lamp.

 

For $1600, you can DIY a new battery pack that is compatible with your Prius. I've done this with my car and have had zero issues.

• I reconditioned my pack with the prolong system not modules swap, I did the charge and balance couple times in about 6 months but still purple SOC every morning so I ordered the discharge did a full reconditioning one charge and balance one discharge and one charge and balance for me this was enough didn’t need more reconditioning my battery it’s performing like never before.

 

I used the full Prolong charger/discharger system for three years on a weak battery and highly recommend it if you can get one or two other members to share the cost. Put a harness on each car and pass the system around. I did finally replace the battery pack with OEM before it threw a code because we were moving to the 120* summer heat in Laughlin. The heat is pretty tough on things.

 

The best fix is a new OEM pack in the first place, but if for any reason is not possible the prolong system can buy you some time.

 

How does it work and how often does it need to be used?

 

Their recommendations have changed some since I bought my system. It used to be the full maintenance with four charges and three discharges every six months and a "charge to balance the system only" session in the middle three months. It's changed now to more of a "use it when it's needed" attitude and the full sessions can only be three charges with two discharges. Too much heating up of the cells by using the charger too often can wind up weakening the system over time.

You can see a better explanation of the whole thing at Hybrid Automotive's website. Here's a good place to start:

Battery Reconditioning Overview | Hybrid Automotive

 

Well, little update here after only 30 days of using the prolong kit (just 2 charge and one discharge) my battery is getting the morning start purple bars again, so doing the reconditioning again and I don’t know if I have the patience for the full 4 charge and 3 discharge but so far moving on my first.

 

It doesn't sound hopeful. You'll be looking for failed or weak modules to replace very soon. Unless you decide to replace all of them at once.

 

You right 14 years old battery even if I replace couple modules the others one probably are not too far behind to fail too, I have 4 cells that charge and discharge more than the others ones but they can keep within the voltage so not trouble code, block 1 and 14.
