Making good Canon LP-E6 battery-pack contacts

battery-pack contacts
Canon LP-E6 battery packs (such as those using in my 70D camera) have two fine connector wires used for charging them.  These seem to be a weak point, as (if left to themselves) they eventually fail to connect well, which means that they do not charge adequately, or (in the field) do not run the equipment at all.

One experimenter discovered that scrubbing them with the edge of a stiff business card helped to make
with (nonCanon this time) charger contacts
them good.  So I considered something more extensive.

Parts: squeeze-bottle of cleaner (I use a citrus-based cleaner from PlanetArk, which seems to be able to clean almost anything off without being excessively invasive); spray-can
equipment required
of WD-40; cheap tooth-brush, paper towels (or tissues, or bum-fodder).

Method: lightly
brush head
spray cleaner onto contacts. Gently but vigorously rub along the contacts with toothbrush. Paper-dry the contacts.

(optional) When thoroughly dry, add a touch of light machine oil. This wards off moisture.

This appears to be just as effective with 3rd-party battery packs.

In this case, it was similar to having the garbage dispose of itself... except for the kidnappees also taken and reprogrammed into psychopathy, as was done to the kidnapper when they were an infant.
