I was happy with the turn out. There were a good number of people there and they seem fairly interested and had good questions. I also enjoyed the...
I am happy that you got that resolved. Clean connections makes such a difference in the Prius. I would also take 05PreeUs' suggestion and...
What ?? Don't understand that comment. The problem often IS that the test is done with equipment NOT designed for that size battery and...
Battery voltage is only one small measure of battery health. A 12v battery fully charged, (at rest) should read ~12.7vdc. The reality is that...
I didn't get to test drive a Prius until about a month after I'd placed my order. The vehicle I test-drove was a 2005 Seaside Pearl fully loaded...
No it isn't. CCA "rating" is pretty meaningless but the test is: Note the resting voltage. Be sure it is within a fairly narrow acceptable...
Hi Tom, Not sure where you are getting that 35 % for a Otto engine. A Turbo diesel is with the typical 20:1 compression and expansion ratio is...
Thor, Your Prius often will pull 100 amps from the HV battery which will result id a higher voltage difference than the one you see at a 5 amp...
For the most part that light bulb test will work. However the modules that would fail when the voltage is low, this test may not catch them. I...
This weekend tests - forgot to mention: In some tests I've discharged every module down to 6V under 6Amp electronic load without dismantling the...
First, realize that inverter is 140w which means it could attempt to draw well over 14 amps if loaded. Some designs may draw a lot of amps on...
Have you tested the amp hours of each module and performed a load test on each to determine that the voltage drop is near uniform for each module...
In the beginning I was using Dr Prius actually. I have the hv battery out now so I can't run the car at the moment but when I was monitoring it I...
Visual is better than thousands of words. I’ve recently published couple of 7 minute videos in HD to give you visual of what is happening with the...
A friend just reconditioned the hybrid battery on his 2007 and within three weeks got the red triangle. Code is P3000. Haven't looked at the...
Thank you so much for the reply. Can you elaborate a little more on the procedure of how to do the load test with the halogen light bulb? Thanks...
Hello i have a 2004 Toyota Prius . 3 Months ago i had the Hybrid battery rebuilt . about 2 weeks ago i had the Synergy drive mechanical pump...
Judging from the design the Yellowtop ought to last longer, but I expect that too few have been in use in Priuses long enough for a comparison....
If you read the reviews for that expensive OTC digital tester, one person said he tested a battery, got a good report from the digital tester,...
Also have an iPhone 3G and will get my Prius 2 with Bluetooth next week. Very interested to learn the results of your test. Thanks for doing this....
