do they still sell the vent tubes new I saw mine was taped together yesterday.

 

$8.07 on rock auto. Part no# SK924253 on Rock Auto.

 

thank you sir

 

Load test is only one dimension of battery performance and does not detect an internal short. That can be caused by sulfating from time spent in a discharged state, and the colder it is, the faster it happens. That’s why everyone runs trickle chargers on stored cars, especially in cold spaces. An alternative is to remove the battery to a heated space, and ideally check the Voltage from time to time and give it a bump when needed.

Another cause of internal shorting is impact that displaces a plate. A mishandled brand-new battery can have this problem. An improperly installed battery that is allowed to move can, too. (Ask me how I know.)

Typically, the internal short problem reveals itself when just one of the 6 cells is affected. In that case, an otherwise good battery will self-discharge to 10.5V or so. (12.6V x 5/6 = 10.5V.) If you let the battery sit and it stops dropping at 10.5V, a single shorted cell is surely the problem.

These cars don’t need anywhere near the cranking amperage the battery can provide. But they often complain if their battery won’t hold 12.5-12.6V. I had an OEM battery that worked fine at over 10 years old. It totally flunked the parts store load test, but was still holding 12.5V.

I used the parts store for the data from their test. Their conclusions and advice are worthless.
