[volt-nuts] A Fluke 732A: Return it or keep it?

[Tom Knox]

I think everyone missed my point, Replace the current battery with ANY other type battery that is not destroyed by deep cyclng. Perhaps Ni-Mh would be better. Ni-Mh also has a very consistent output voltage (Low voltage drop) until nearly discharged. Also a quick Google search found a wealth of information on shipping Li-Ion and it appears the 732A batteries are right on the edge of no shipping restriction.

Also you are no longer allowed to put batteries in you checked airline luggage, only carry-on and there are limits on the Lithium content (now expressed in WH to make it easier). This is pure safety addressing a very real hazard. The krytron restriction is ITAR (google it) as they are used to fire slapper detonators in nuclear weapons (that probably got a ping on a monitoring service;-).
