Lithium Thionyl Chloride Batteries
Sensys Networks uses Lithium Thionyl Chloride batteries in the following
products:
• Sensors (VSN240-F, VSN240-T, VSN240-S)
• Repeaters (RP240-B, RP240-BH, RP240-B-LL, RP240-BH-LL)
Lithium batteries are widely used in electronic products because they contain
more energy per unit -weight than conventional batteries. However, the same
properties that deliver high energy density also contribute to potential hazards
if the batteries are damaged. Improper use or handling of the batteries may
result in leakage or release of battery contents, explosion or re.
Following are the recommendations of the battery manufacturer for proper
use and handling of batteries in the Sensys Networks devices mentioned
above:
• DO NOT charge or attempt to recharge the batteries (batteries are
NOT rechargeable)
• DO NOT crush or puncture batteries
• DO NOT short-circuit the batteries
• DO NOT force over-discharge of the batteries
• DO NOT incinerate or expose batteries to excessive heating
• DO NOT expose battery contents to water
• DO dispose of batteries and devices containing batteries in accor-
dance with local regulations
Sensys Networks sensors contain no serviceable parts and should never be
disassembled. Installation and removal of sensors from pavement should
only be done by trained personnel and care should be taken to insure that the
sensor casing is not punctured or crushed.
