Closed Circuit Voltage (incoming inspection test) The open circuit voltage reading, no load applied, of a battery or pack can be misleading. A closed circuit voltage test, battery under load, is used to create a voltage drop in the battery. The amount of the voltage drop is a good indication as to the condition of the battery battery. Multiply the number of cells in the series pack by the load resistance. Multiply the number of cells in the pack by the “minimum voltage per cell to pass”. Example: 4 E91 series battery pack 4 x 10 Ω = 40 Ω Load 4 X 1.4 volts = 5.6 minimum pack voltage to pass Load Duration (Seconds) Min. Voltage per cell to Pass E95 10 Ω 2 to 5 1.4 E93 10 Ω 2 to 5 1.35 E92 43 Ω 2 to 5 1 35 1.35 E91 10 Ω 2 to 5 1.4 L91 3.9 Ω 2 to 5 1.4 Important Notice This document contains general information regarding design considerations. ©Energizer Holdings, Inc. - Contents herein do not constitute a warranty. 1 of 1
