There would be a UL or CSA symbol on it. Take a look at most any other electrical or electronic gear, even a lamp. Likely you'll see a piece of paper around the cord, on it will be a UL. Or a laptop power brick, for example.
For CSA, it's a C (almost a complete circle) with an SA in the middle of it.
Not sure either would be on a battery, for sure, but I wondered - given stories of batteries overheating or fires. Not saying it was these ones or any other ones. I just see elsewhere in the thread concerns about temperature on these larger batteries, and every so often I come across some sort of horror story. I'm guessing, especially if things are coming from outside North America, so don't have to adhere to these safety standards.
Not saying there is a danger, just wondered if one of these symbols was present.
Thanks for checking for me, though.
'course if people are stupid enough to short the terminals ... but then, that's why there are Darwin awards, I suppose.
