^^^^^ yes, exactly what i use. Easier if trim a couple of mm off first(variable of course) and simply just use a hair dryer to shrink! Its also worth getting a few pos end protectors whilst at it for any repairs or future repairs.
Some really good ideas in here;
I'll use anything 'short' () of aluminum foil to stop battery rattle in my lights; my typical solution is mylar due to its moderate resistance to curvature - in the same manner of a leaf spring, it retains a very slight bias towards maintaining its original shape, and subsequently holds to the interior of a flashlight body somewhat better than paper products.

Is Mylar conductive?
I'm not sure that I completely understand what you're saying here? How does side to side motion of a battery or batteries have any impact on the linear force/pressure placed on the positive post? I'm even less sure as to the effect on the "threads of the adjuster screw".I tend to leave my battery just the slightest bit loose so it's not crushing the positive post and putting undue stress on the threads of the adjuster screw when I fire it.
