BAD... The manufacturer is lying to you. There is no such thing as a "pulse" rating because a pulse is not a defined value. How long is a pulse? I figure, if a manufacturer has to misrepresent its product by putting an unknown value, I want to avoid them. You notice, the most often recommended batteries, Sony, Lg, Samsung have no pulse rating? They don't need to make any false claims, their quality stands on its own.
I am not telling YOU to do this, I have done a lot of research and study on this... but..
My cloud builds are on a samsung 25r. Now I know those are safe, authentic brand name batteries. I also know what they have been stress tested at. I also know that MY pulse is 3.5 seconds. 1.5 second exhale and 2 second inhale. I also know that the samsung 25r has been stress tested to perform safely at UP TO 70Amp draw for 5 seconds, with a 30 second rest between firing. This tells me that my 40amp fire for 3.5 seconds is well below what the battery has been stress tested to handle. For added safety, i take my battery out and check it for heat in my hand. If it is getting hot, i put it up for awhile. Mind you, it shortens my battery life, but you can't have everything. I figure if the battery is hotter than your bath water, its time to give it a rest.
