DOD-STD-2134

Abstract

This standard covers the arrangement of storage batteries and the arrangement of connections to storage batteries, in a manner that will reduce the stray magnetic field, produced by the current, through the batteries and their associated connections to a minimum. <br>The general requirements of this standard (see section <a>4</a>) are applicable to the arrangement of all types of storage batteries, where a minimum stray magnetic field is desired. The detailed requirements of this standard (see section <a>5</a>) are applicable to the arrangement of 6-volt DOD-B-15072 storage batteries aboard minesweepers and submarine lead-acid storage batteries covered by DOD-B-24200 and DOD-B-24541. Requirements specified herein are normally applied during ship construction, overhaul, ship alteration or ship repair. Requirements which are within the ship's capability may be applied by ship's force, as needed. <br>The three-cell, 6-volt battery tray arrangements covered by this standard shall be of the following types: </span><pre> Type I - When looking down on the top of the tray, with the cells oriented in the vertical direction, and the top cell terminals being negative-positive from left to right, the external negative battery connection shall be made at the top of the tray and the external positive battery connection at the bottom of the tray as shown on <a>figure 1</a>. Type II - When looking down on the top of the tray, with the cells oriented in the vertical direction, and the top cell terminals being negative-positive from left to right, the external positive battery connection shall be made at the top of the tray and the external negative battery connection at the bottom of the tray as shown on <a>figure 1</a>.</pre> <br> <br>
