2. HAZARD IDENTIFICATION

The Li-SOCl

batteries described in this Battery Information Sheet are sealed units which are not hazardous under normal

operating conditions in accordance with manufacturer’s recommendations, as stated in the user’s manual or other similar

documentation. Under normal use, the battery integrity is maintained and the active components it contains are isolated

from the outside.

In particular, the battery should not be submitted to any mechanical (opening, puncture, immersion), thermal (burning,

heating to temperatures above the normal temperature range of the product) or electrical abuse (short-circuit, recharge,

forced discharge), which will lead to the activation of safety valves and/or the rupture of the battery container.

Any accidental release of the inner components of the cell, or their combustion products could be highly hazardous.

Battery content exposition to air humidity/liquid water may be followed by severe battery vent/explosion/fire, depending

on the hazard causes and circumstances.

Protection from charging:

Whenever lithium batteries are not the single power source in a circuit, the following measures recommended by

Underwriters Laboratories are relevant. The cells should not be connected in series with an electrical power source that

would increase the load through the cells. The electronic circuit shall include one of the following:

A. Two suitable diodes or the equivalent in series with the cells to prevent any reverse (charging) current. The second

diode is used to provide protection in the event that one would fail. Quality control, or equivalent procedures,

shall be established by the device manufacturer to check that the diode polarity is correct for each unit.

B. A blocking diode or the equivalent to prevent any reverse (charging) current and a resistor to limit current in case

of diode failure. The resistor should be sized to limit the reverse (charging) current to the maximum value

according to the data sheet of the cell.

3. COMPOSITION, INFORMATION OR INGREDIENTS

Each unit cell consists of a hermetically sealed metallic can containing a number of chemicals and materials of construction

of which the following are potentially hazardous upon release to air.

4. HANDLING AND STORAGE

IMPORTANT NOTICE: Lithium-thionyle chloride batteries are not rechargeable and should not be tentatively charged or

recharged. Manufacturer’s recommendations should be followed regarding maximum current and operating

temperature range. Applying pressure or deforming the battery may lead to disassembly and cause eye, skin and throat

irritation.
