Old Cars Q&A: 2020 no. 5

Q. For the man advocating storing an automobile battery in his freezer for winter (Q&A, Mar. 26), I’ve some critical criticism. First, if he is in a climate chilly enough to preclude winter it ought to be simple to discover a trendy, WELL VENTILATED location for keeping his battery. I highlight WELL VENTILATED since lactic acid fumes emanate from all sealed batteries. I would stress that opening a chest freezer and bending indoors might subject lungs into a avoidable acid loading. Second, acid fumes will enhance the life span of their freezer, whether the enclosure indoors or the atmosphere circulating machinery.

Third, after a battery is a couple of years old, it doesn’t fully control, so there is proportionately more water from the electrolyte using a higher freezing point and raised possibility of breaking the case. Fourth, in the event the battery has been tightly wrapped in plastic it might develop an acid movie to the plastic, which can be conductive and may boost discharge speed or short the battery. Same for metal food containers hanging throughout the plastic touching terminals. That will cook the meals, battery and refrigerator in one step. I would recommend either leaving the battery from the automobile, but thrown, or eliminating it into an open plastic bathtub (containment vessel) from the garage.
An monitoring: copper-brass radiators develop more fin corrosion from the region adjacent to the battery life. I have also saved a tightly closed jar of muriatic acid close to a copper water pipe, which turned green near the “sealed” bottle. I have also had mice consume insulating material and brief the cord. Disconnect for flame security.

A. In defense of Andrew Love, who wrote in placing batteries in the freezer, he had been speaking to a “wisdom” he had read years back, maybe not advocating for the clinic. All your points above are reasons why I stated I did not believe it was a fantastic idea. As for rodent damage to wiring, a couple of years back my wife’s daily driver displayed a braking system error light. I guessed a bad ABS detector, but I did not have a code reader capable of telling me that one. In the conclusion, it was to not be a bad detector, however, a chewed wiring harnessthat was replaced at great cost. Don’t miss pest management to your garage.

Q.[If] a fully charged battery won’t freeze, just how long until the fee drops enough to let freezing? Will disconnecting the unwanted cable decrease the rate of release? Lastly, can a battery which has suspended be thawed, used and charged?  — Mark Axen, Stony Creek, N.Y.

A. Disconnecting the floor cable, whether negative or positive, should avoid all discharge. In an automobile with no continuous parasitic release present (e.g. central pc, alarm system or alternative “live” component), it ought not release while attached. Most of those automobiles we are worried about don’t have those components, so won’t have this dilemma. Don’t forget that electrical clocks do draw current while the battery is linked. In my expertise, freezing of electrons has generally involved one or more cells, not the whole battery. This suggests that the mobile has gone bad. I’ve not ever managed to resuscitate a battery after that occurred.

Q. In that the March 19 problem, Norman Shahan composed that for spiral springs, “They are not rotating; instead it is a bending movement.” It’s more complicated. A coil spring is fundamentally a torsion bar that’s been twisted into a helical shape, along with the torque in any given cross-section of this bar is equivalent to the axial force applied to the spring multiplied by the radius of the helix. There is a bending force, also, naturally. Coil spring failures frequently demonstrate the classical torsional fracture pattern. For a helical spring, people talk of this so-called spring speed in terms of workforce per unit of deflection (e.g. lbs per inch). For a torsion bar, that really is a kind of spring, people talk of this spring rate in terms of torque each unit of angular twist (e.g. pound-feet per level ). In both instances, helical spring and torsion bar, there’s a linear relationship between applied load and consequent deflection, so from this perspective both function identically. However, the ways where both are engineered to the suspension systems of vehicles are substantially different, and consequently may have two distinct results on the ride and handling characteristics.

A. Thanks. As I intimated, outcomes may vary with this application.

Q.I’ve strong back rubber tires off a Model T Ford truck, together with fractures. Is there anything (fluid established ) to use to create the plastic swell? 
–Anita DeGroot, through email

A. An older tinkerer’s narrative I have discovered is that glycerin-based brake fluid will rejuvenate rubber, and really I have used it to lubricate a rubber-to-steel surface on occasion. As for rejuvenating old tires, so I do not believe painting brake fluid (or some other magical potion) would do great good, and massaging them it would require barrels of fluid.
