Battery Safety
Battery Transportation
Rechargeable lithium batteries are subject to special regulation by U.S. and International
laws, particularly regarding transportation on passenger aircraft. However, individual
batteries installed in consumer electronics are not restricted, provided there are only
the correct numbers and types of batteries as may be needed to operate the electronic
equipment.
Your Tempest Wireless Intercom System includes rechargeable lithium-polymer batteries that power the BeltStations. To ensure that there is no
violation of U.S. or International laws, and to ensure your own safety, always:
• Transport rechargeable lithium batteries installed in the equipment they are intended to power.
• Transport spare batteries in a padded case, separated from one another.
• Never transport your rechargeable lithium batteries bundled together.
• Never transport more than 12 lithium batteries in a single package.
Lithium-polymer batteries include a chemistry that is intended to overcome the dangers associated with lithium ion batteries. In addition, the
batteries that accompany your Tempest Wireless system include protective circuits to further reduce the possibility of a dangerous reaction
associated with charging or discharging beyond safe limits. With reasonable care you can expect many years of safe and reliable power from
your batteries.
Tempest batteries are not subject to transport regulations of dangerous goods because they fulll the following regulatory provisions:
• ADR 188
• IATA A45
• IMDG 188
Battery Storage
Long-term storage of batteries at maximum charge can result in permanent loss of capacity.
For long term storage of batteries, charge/discharge the batteries to approximately 60% of capacity. Batteries stored for longer than one year
should be recharged to 60% annually.
Trickle charging is not recommended due to the very low self discharge rate of the batteries.
As with all batteries:
• Do not burn.
• Do not expose batteries to excessive heat such as sunshine, re or other heat sources.
• CAUTION – Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
• Properly dispose of used batteries promptly.
• Keep away from children.
