While that should be OK, an AGM when fully charged will be higher: from 12.9 to 13.1
It still could have failed.
The WD40 is not working because........it is NOT intended to be a penetrating oil. Get some real penetrating oil. Apply that and a little heat...
Shop around to other car audio places. Do the speakers first. The radio itself might be fine. In a 15 year old car, you don't NEED top of the line...
"- it's a heavy, somewhat floral/syrupy odor" That fact might indicate that the previous owner went WAY overboard in trying to cover up the dog...
will a new 12v save a failing hybrid battery ? NO. But it might allow the computers to recognize that the hybrid battery is really NOT going bad.
How will applying + 12 V on two pins of any device without an appropriate negative connection prove anything ?
There really is no such thing as a "reconditioned" battery. They replace the worst cells and give you back all of the other old ones that still...
Good advice. BUT.....one should not trust a single test. It needs to be repeated 3 times in a row with about a minute in between each test. That...
First, you need to test the "float" voltage of your tender and the charging voltage while the car is running. If both of those looks...
It is cracking due to age and heat......and sometimes cheap construction. Real "rot" results in a condition where you can poke the tire with your...
Yep. It's shot. Start shopping for a new one. What is the voltage while the charger is still connected and it indicates a full charge ? What is...
BUT it has to be in the READY mode for a while to charge the 12 V battery back up. And by "starting up" the gas engine should run long enough to...
But the charging voltage will be similar and should be checked EVERY time you change the battery or suspect a 12 V system problem.
Batteries from a junk yard are often.......JUNK. That is not generally good advice. And even if you don't need an AGM type battery, they almost...
Lots of good information in this thread. The overriding factor might be: You have a car that is 16 years old. It didn't have a LOT of power when...
AND if that information is not good enough for you, you should be able to take the VIN (or the whole car) to any Toyota dealer where they can look...
You do understand that Greenbean.......and other "rebuilders" ........replace only the "bad" cells and the rest of them are still "old", right ??
OK, I give up. "convention" has bastardized the term. All cracking of rubber tires is NOT a sign of true "dry rot".......but that is the way...
You probably aren't doing anything differently and it is just a coincidence. How old is the battery ? Maybe you could have her "check" it after...
