Abstract
A battery, a battery container, and a battery pack, for use downhole in MWD operations, one or more of which incorporates lateral vibration damping. In a preferred embodiment each comprise specialized lateral vibration damping in the form of a plurality of longitudinally-extending resiliently-deformable ridges extending substantially a length of each and circumferentially spaced about an outer periphery. The resiliently-deformable ridges on the battery may be integrally formed and extend radially outwardly from a hollow resiliently-deformable sleeve, and formed of the same resiliently-deformable material of which the sleeve is comprised. The resiliently-deformable ridges on the battery container may extend radially inwardly or outwardly from a periphery thereof. Advantageously, the battery container can thus be free of potting material and thus be reusable when the batteries thereof need be replaced. In all instances the so-configured resiliently-deformable ridges serve to damp severe lateral vibratory forces exerted downhole on such batteries.
