I have a huge (28 kg mass) automotive high-current battery charger, and its current delivering capabilities are described like that:

70A moy/arit 90A eff

What do these mysterious abbreviations "moy", "arit" and "eff" exactly mean, and how much current can this beast really deliver, 70A, 90A, what's the difference between the first and second number?

Here is a photo, so you have an idea what kind of device it is: http://telto.nazwa.pl/allegro/15.10.2010/d/dscf1313.jpg


I think those are French abbreviations. I believe "moy/arit" is an abbreviation of "moyenne arithmétique," meaning "arithmetic mean," or average.

I'm not sure about "eff," but I bet it's an abbreviation for a French word for "peak."

"moy" or "moyenne" most likely refers to "average" and "eff" or "effusion" is most likely put here to signify "burst"... as in some sort of vehicle jump mode.

(idea stolen from my dinky battery charger at home that has 10A continuous and 30A "burst" capability for helping to jump a car)
