Cells leakproof up to +95°C. Most cells are UL recognized.
Operating temperature range: -60/+70°C.

Abusive conditions could adversely affect the performance of the Li/SO battery and result in cell
2
venting, rupture, explosion, or fire. Preventive measures are discussed in Sec. 14.4.
The Li/SO battery is pressurized and contains materials that are toxic or flammable. Properly
2
designed batteries are hermetically sealed so there will be no leakage or out-gassing, and they are
equipped with safety vents that release if the batteries reach excessively high temperatures and pres-
sures, thus preventing an explosive condition.
The Li/SO batteries can deliver very high currents. Because high internal temperatures can
2
develop from continuous high current drain and short circuit, batteries must be protected by electri-
cal fusing and thermal cutoffs. Charging of Li/SO batteries may result in venting, rupture, or even
2
explosion and should never be attempted. Cells or groups of cells connected in parallel should be
diode-protected to prevent one group from charging another. The balanced Li/SO cell is designed
2
to handle forced discharges or cell reversal and will perform safely within the specified bounds, but
design limits should not be exceeded in any application.
Proper battery design, using the Li/SO cell, should follow these guidelines:
2
1. Use electrical fusing and/or current-limiting devices to prevent high currents or short-circuits.
2. Protect with diodes if cells are paralleled or connected to a possible charging source.
3. Minimize heat buildup by adequate heat dissipation and protect with thermal cutoff devices.
