Can someone tell me the difference in these and how you choose one over the other?
Thanks!
Thanks!
The GA has more capacity, maintains higher voltage under the same load, and can deliver higher current. But it has no PTC.

Mainly cost like you said, but I have found that some protected GA cells to be a little fatter in diameter than the B cells. As far as non-protected cells go, I think I favor the GA over the "B" because of the raised positive terminal. It's not a flat top like the B cell and its not a button top either.......somewhere inbetween and that makes the difference on some flashlights that won't accept a flat top.Ok thanks, with what you have said, COST ASIDE, why would one choose the "B" cell over the "GA?"

Ok, one more, is cost also the only reason that someone would want, say a 2400mAh battery vs. 3500mAh battery? My feeling is, since I don't have dozens of batteries, I'd rather just get the longest lasting b/c the cost difference to me is negligible. Thanks!
Somehow I think by the time one of our modders builds a light like one that takes a 20+ amp battery, will be the day they get sued out of business. That's a huge amount of current flowing thru a few wraps of coiled spring and solder braid for contact.The ncr18650b unprotected or with pcb circuit added fits in the majority of flashlight. If you plan to buy a modified one, you will surely need a cell that can give higher disharge current (10-20-30-40A) instead of the 5A that the 18650B give.
Until now, I use the ncr18650b in all my lights.
HRL and CID are present like in the B type. Only the PTC is missing, as in the other 3500mAh cells SDI 35E, LG MJ1.No PTC? What internal protection mechanisms is the GA using? A heat resistive layer?
