slow starter follow up

I'm not a big fan of some load tests. I prefer the VAT-40 or the VAT-28 made by Sun. Excellent testers. A guy at work asked me to put a starter in his Toyota Tacoma because the battery tested good. When I raised the hood I saw a 7 1/2 year old battery. I told him to do the battery first and see. The battery fixed it.
 

Tell us how you determined that...

Modern day conductance testers are nuttin more than a guess I see it all the time... Why folks fight a simple voltage test I dunno I guess they like to fudge with it and hope they get lucky...

Once in a blue moon I dust off my hydrometer then ask myself why did I waist my time when a voltmeter would have shown it had a weak cell that I already knew....

I know folks have a good heart and step up and help BUT at the least they could do is ask the poster to give them some voltage readings before they send them guessing... Is it that hard to do...

Is it, if it is then you miss a good chance of learning sum'N...
 
Hobo...Here's the deal...I
did post a voltage on the FB
site...neglected it
here...6.4 volts on the
bench...6.2 after spinning
the starter for a minute...A
percentage function on a
Digital charger showed a
battery percentage at 60 percent that had shown 100 before spinning the starter...yet hydrometer and load test both showed a good battery..
NAPA initially was not going to allow me to return the battery cause "there was nothing wrong with it"....I had purchased a second new battery from TSC..NO ISSUES whatsoever in the 41...I told him that...and that the battery WOULD be returned...it was then that the "expert" at NAPA said he suspected that the battery had been filled with water and not acid...can't make stuff up...

ow many amperes was the load test?
 
(quoted from post at 10:17:54 08/15/19) Very good question, JMOR.

Dean
es, those little HF hobbiest load testers run about 20 amperes & about 400 amperes are needed to be meaningful.
