Is it safe and ok to put 4000mAh 18650's into Fenix PD32's etc?
I have read enough info online about lithium batteries and have been using them for years. This thread is more specifically about using that capacity, specifically in fenix flashlights. But it seems the manufacturer lies about the quality/capacity of their cells so I would not even bother any way. I was recommended to get Keeppower cells, so when I am in the position to switch from RCR123 to 18650 I will go that route instead. I would take reliability over fake capacity/bad brand any day.You owe it to yourself to read a bit in the battery section so that you will at least know the safety precautions when using these batteries.

IThe best deal at present I'm aware of is Fastech, where you can get TWO 3400 mah 18650's for about $17. These fit most stuff, but are a hair larger than the Eagletac 3400 mah 18650's, which fit into everything.
I'm with you. It's a shame that manufacturers can claim stuff on their labels that aren't true. From what I understand very few (if any) rcr123s with accurate stated capacity. 18650s are a bit better on their claims (excluding much of the *fire batts) and it's favorite form because of greater capacity and the ability to use in some of the pocket friendly single cell lights.I have read enough info online about lithium batteries and have been using them for years.

Wasn't those the unprotected NCR18650A ones though? If I was going to buy any right now it would be the NCR18650B protected version of the battery.

Perhaps they base it on how they make them and what their numbers say it "should" be.. ?I think they either lie out right, as in the ones where whatever the competition has, theirs is more....or, they test the run time with very very low draw, perhaps parasitic losses.
