## Questions & Answers

**Q: Will this work with the older Protac 2L?**
A: No! Just a hair too thick... I have the 2L also, so I thought it would too, but it did NOT, bummer!

**Q: Are they AA batteries**
A: No, these are an 18650 3.7v lithium battery with a usb charger on the end of it, making it a bit longer than a standard 18650. So it is larger than a aa battery in every dimension, and has over double the voltage. The added length because of the usb charger cap means it also probably won’t be usable in most 18650 applications. But on the plus side, if you just need a 3.7v lithium ion source, and don’t want to have to use a special charger, this could be used and recharged with a micro usb cable.

**Q: will this work in the HLX 1000 Weapon light?**
A: I have the flashlight based on this pic rail mounted light.  The Streamlight branded battery will fit.  There is enough room in the case to accommodate the longer length of the battery.  It is one of the few Streamlight single cell flashlights that will.

**Q: Can i use these for a vape?**
A: Almost all vapes will use a flat top design so try looking up 18650 flat top
