A couple of my clients have struck trouble recently, being prevented from t= aking=20 sealed lead acid batteries on planes, either installed in equipment or stan= d alone.=20 Occurred on International flights and US domestic flights. Check in or carr= y on the=20 batteries were not permitted to fly. I've since looked around for info, found various requirements for travellin= g with=20 Lithium batteries on www.iata.org, but not much on Sealed Lead Acid, only t= his... http://www.iata.org/whatwedo/cargo/dangerous_goods/Pages/passenger_faq.aspx "(click answer for bottom question, "I am handicapped and want to travel wi= th my=20 battery powered wheelchair...") Similarly the batteries I want to fly are non-spillable sealed lead acid (s= mall ones,=20 12V 2AH). The transport section in a Panasonic SLA battery datasheet reads = like=20 this: Identification and shipping name: Batteries - Wet, Non-Spillable, Electric = Storage,=20 UN 2800 DOT - Unregulated, meets the requirements of 49 CFR 173, 159 (a). IATA/ICAO - Unregulated, meets the requirements of Special Provision A67. IMO - Unregulated. For all modes of transportation, each battery and outer package must be lab= elled:=20 "Non-Spillable" or "Non-Spillable Battery." This label must be visible duri= ng=20 transportation. Batteries must be securely packed to prevent short-circuiti= ng. Seems to me the chances of travelling should be good if the battery is spec= ified as=20 Non-Spillable, and the batteries and/or equipment/outer package is labelled= as=20 described above, and the battery Material Safety Data Sheet is presented to= the=20 airline. Probably means using good known brand batteries and not not cheap = un- known types, but that's reasonable. Wondering what other people have experienced, other steps to recommend? --=20 Brent Brown, Electronic Design Solutions 16 English Street, St Andrews, Hamilton 3200, New Zealand Ph: +64 7 849 0069 Fax: +64 7 849 0071 Cell: +64 27 433 4069 eMail: brent.brown@clear.net.nz --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
