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

[Tom Miller]

Some laptop batteries are not allowed. Spares have some limits also. Better 
check because TSA will take them from you.


 Lithium-ion batteries (a.k.a.: rechargeable lithium, lithium polymer, 
LIPO, secondary lithium). Passengers may carry all

consumer-sized lithium-ion batteries (no more than 8 grams of equivalent 
lithium content or 100 watt hours per battery). This

size covers AA, AAA, cell phone, PDA, camera, camcorder, handheld game, 
tablet, and standard laptop computer batteries.

The watt hours (Wh) rating is marked on newer lithium ion batteries and is 
explained in #3 below.

Passengers can also bring two (2) larger lithium-ion batteries (more than 8 
less than 25 grams of equivalent lithium content per

battery or about 100-300 watt hours per battery) in their carry-on. This 
size covers the largest aftermarket extended-life laptop

batteries and most lithium-ion batteries for professional-grade audio/visual 
equipment. Most lithium-ion batteries are below

this size.
