Battery Precautions
• Before disposing of a battery, check your local laws, rules, and regulations, and
follow them accordingly.
• Transportation of lithium-ion batteries is regulated by the United Nations under
the United Nations Recommendations on the Transport of Dangerous Goods. It is
expected that governments, intergovernmental organizations, and other
international organizations shall conform to the principles laid down in these
regulations, thus contributing to worldwide harmonization in this field. These
international organizations include the International Civil Aviation organization
(ICAO), the International Air Transport Association (IATA), the International
Maritime Organization (IMO), the US Department of Transportation (USDOT),
Transport Canada (TC), and others. Please contact the transporter and confirm
current regulations before transportation of lithium-ion batteries.
• Do not open, crush, or perforate batteries; doing so could cause injury.
• Do not incinerate batteries. Keep batteries away from fire and other sources of
extreme heat. Exposing batteries to extreme heat (over 80 °C) could result in an
explosion or personal injury.
• Do not drop, hit, or otherwise abuse a battery, as doing so could expose the cell
contents, which are corrosive and explosive.
• Do not short-circuit the battery terminals. A short circuit could cause injury and
severe damage to a battery making it unusable.
• Do not expose a battery to moisture or rain; doing so could cause an electric
shock.
• Only use the EPOCH 6LT unit or an external charger approved by Olympus to
charge the batteries.
• Only use batteries supplied by Olympus.
• Do not store batteries that have less than 40 % remaining charge. Recharge
batteries to between 40 % and 80 % capacity before storing them.
• During storage, keep the battery charge between 40 % and 80 %.
• Do not leave batteries in the EPOCH 6LT unit during instrument storage.
