Prolong Battery Systems featured in Parts & People Magazine

Yes but take it one step further. We've created the ability connect to and begin cycling a full pack in seconds, without removing it from the car. This can be done as many times as needed for the rest of the life of the vehicle. Hybrid battery reconditioning is not a one time event. If done once and never again, then in 9-15 months the battery will be right back to the imbalance 'failed' state that it was in before reconditioning was performed - exactly what happened to your Dorman pack. If hybrid battery reconditioning is performed as an ongoing service maintenance to the battery every 4-6 months, then years and years of incremental battery life are suddenly very attainable. This is the unique ability of our products, and what our patents are filed around .

If there is a module with a known failed cell, odds are it will have to be replaced. No amount of cell cycling will repair an internal short or excessive IR cell, regardless of what charging & discharging device is used. If we have a professional user/reseller with a customer car with a possible 'failed' cell in a module, we always recommend replacing the module to eliminate the chance of a customer "come back". If it's a private individual and the red triangle just appeared for the first time, we might recommend they to try cycling the pack with the weak module still in it to see if the cell will come back. In these cases, it's a 50/50 chance that reconditioning alone will recover a borderline cell - and we always tell customers this up front. If one is a private individual with time to tinker on the car, then those odds are worth giving it a try. If they don't want to mess with it, then we connect our customers with a trusted module supplier and have them replace the borderline module up front. Shops/professional users can't take the risk of the repair not working for the long term, so they should replace weak modules even if they are not 'fully' failed yet.

For your Dorman pack, assuming you are testing resting voltage, then I would say the 6.32V module is likely gone. If it tests that far down in voltage without any load, I doubt it will recover and be able to sustain the high current loads being applied by the car. But if you have time to try it, then sure why not

We recommend load testing each module to determine health and assess for replacement. Our low cost consumer load tester applies a 5A load to each module using an H4 12V bulb wires in series. Our professional grade load tester/IR calculator will apply a 60A load to better simulate what the modules/cells experience in the car (It will also have a 20A module capacity measuring capability). It is designed to help battery rebuilders identify and replace weak modules when working on packs and/or customer cars.

 

Sweet! Thanks. Should Ship Saturday or Monday at latest

 

Well our latest batch of cooling fans is not up to our standards . We ordered replacement fans with expedited shipping, but all pending Prolong Discharger orders will be on hold until we can replace the fans. New shipping estimate: Wednesday 5/3 or Thursday 5/4

 

Yes, you will need to cycle the pack once the replacement module is installed. At least 2 times, ideally 3. We can connect you with a trusted supplier of quality used modules if the one you have doesn't work out.

 

Correct. This is how to do it. I need to get the website update but have been behind. It's coming soon I promise :-/

 

OK, I finally sat down and started a "Prolong® Battery Discharger User Guide" page on our website, located here:
Prolong® Battery Discharger User Guide - Hybrid Automotive

You guys can help me out: Is there any information you want to see that is missing? Anything confusing or unclear?

Thanks in advance for any feedback.

 

Yes, correct on both counts

 

Sorry yeah. The images on our website can be clicked on to enlarge them, but it you are offline that wold be hard to do . . .
