Nitecore NL1823 18650 2300mAh 3.7V Protected Lithium Ion (Li-ion) Button Top Battery - Blister Pack

found that I need to order some of these that are "Flat tops" to fit other items. All my flashlights have springs inside which allow you the extra space for button tops. I will be ordering some of these in flat top for other things with a tighter fit. So far these have been some of the best 18650 batteries I have used. Well worth the money.

harged them then went to put them in the battery compartment, they did not fit. I contacted customer service and i was told that there is different lengths for the 18650 batteries.

This was my mistake for not researching enough about the batteries and include the story in this review to help others. The difference in length is around .100”, so it can be significant depending on the battery compartment.

I will be purchasing again from Battery Junction, they seem to be s good company to deal with. Read LessRead less about The batteries arrived as described,
