Test and Evaluation of MK 37 Torpedo Batteries.

Abstract

The exercise and warshot batteries for the MK 37 torpedo were tested against the electrical specifications of the manufacturer. Both battery types failed to meet the minimum power requirements during the three-second, high rate (130 A) portion of the discharge. The warshot batteries performed as specified for the main part of the discharge test. Due to the limited number of test batteries examined it was not possible to estimate the cycle life expectancy for the rechargeable exercise battery. Electrolyte levels within some cells of the exercise battery were found to decrease over a time interval of several months. Additional electrolyte should be provided as a routine servicing procedure. Some indication of imminent cell failure is provided by the open circuit cell voltage after at least a one day stand. Low open circuit voltage may be taken as sufficient reason for the replacement of the 4-cell monoblock in the exercise battery. (Author)
