Lithium in BP-U60?

Anyone have a clue how much Lithium is in the BP-U60? Figure with the new TSA lithium rules it would be helpful to know.

thx...jw

I assume you want to know the following BP-U60 = 14.4v 3.9Ah

Thanks, but what I asked is how much lithium there is in these batteries so that when a TSA person asks, then I can tell them.

The new lithium rules website gives an estimate of 8 grams of Lithium in a 100 watt hr battery, so if I knew the watt hr rating of the BP-U60 I could make a reasonable estimate.

Just received this email from our sales rep at Abel Cine

Jim-

Thanks for the call. Here is what we came up with.

Each of the Sony BP-U60

I would hope the NTSB and/or the TSA can come up with specifications for cases that would allow these batteries to be transported safely rather than waste time calculating metallic lithium equivalents.

Perhaps Nomex-lined, baffle-vented steel cases that can contain a small lithium fire. Keep the batteries from shorting and, if one should go off, prevent them from igniting anything nearby.

If it's possible for hunters to transport ammo, why can't professional camera crews transport batteries?

Lithium batteries aren't inherently dangerous. It depends on the design. For example, A123 Systems batteries, like the ones found in DeWalt power tools, can be drilled and not explode.

One would hope that the TSA can come up with a solution, but it's not likely anything will change in the near future. Also regarding the power tool batteries and explosion. From what I've read, explosion is not the problem it's the high temperatures in a lithium fire that causes the concern.

The lithium polymer batteries used by radio-control hobbyists have been known to go off every once in a while. It's become enough of a problem that someone came up with a bag to contain the battery as it's charging. It's been proven to prevent a burning LiPo battery from igniting anything nearby.

The resulting battery fires tend to flare a bit but it's mostly the acrid smoke emitted that seemed to be the biggest problem.

Maybe lithium-ion batteries burn hotter.

Something like a surplus military steel ammo can should easily contain the fire. I don't know if these fires are self-sustaining. If not, the enclosed ammo can would be enough to snuff out any further combustion.
