Charge the battery and let it play out. I had a similar scenario when testing my Prius battery at Autozone, it tested bad. This was 3 years ago...
Quick analysis and constructive feedback for S Keith graph: Current dropped from 20A to 0 (zero) at the cut-off voltage of 6V on the module....
What is the age of the 12V battery, if you bought the Prius used you may not know????? Just checking with a multi-meter is good but not...
Those numbers don't look like a cause for concern. You will need to do some load testing or use the Dr. Prius test to see what might be the cause...
It's true that a simple open-circuit voltage test won't really test the ability of a battery to supply enough current to crank an engine. But...
A -proper- test of a automotive 12V lead-acid battery is a "load test". You can do this by simply turning on the headlamps while measuring the...
If you go to Youtube and enter into the search bar: "load test prius hybrid battery module" you can watch a bunch of videos about how to do it....
Well ... a typical load tester is likely to put a higher load on it than a Prius would ... so it comes down to interpretation. If the load tester...

I have a 2010 Prius with the original Batt. I have it load tested yearly at Walmart. Still good.
There’s no later. I would replace that battery. Stop exposing the car to jump starts it’s so easy to Cause extreme damage to a prius with a bad...
Update!!! I had the battery tested at an auto supply store and their test machine showed "slightly low charge", so they put it on their bigger...
I disagree, a load test is a test of a batteries health. If a battery can't do what it is designed to do then it is weak or bad. I don't know...
Hello everyone, I am looking for some information on the best way to test each of the individual 28 modules in my 2008 prius's hybrid battery to...
How do you know they are at 8v? Did you test while they are under load? That is what matters. See this video from pc member kiwi Prius...
Okay good to know, I am not aware of that, so I am assuming it doesn't let you test that. Basically we watch the battery for the modules as we...
This is the OBD2 wifi reader I use with the Dr Prius app to load test the battery [MEDIA]
It is also recommended to provide an auxiliary 12v source to maintain the computer voltages while you have the Prius battery disconnected. In...
See Brad's post. There are no errors in the capture. There was no change in load except at the termination of the test. They are very easy to...
