I agree, contact Provape's customer service about your issue. I'm sure that they will offer some suggestions to try. I'd appreciate to hear what their recommendations are.
Some things to check first though:
Adjust the snugness of the battery cap. Sometimes just loosening it just a hair or two can provide the improve the contact between the Provari and the battery.
Compare the springs in both caps to see the distance that they protude from the floor of the endcaps, respectively. The extended cap might have a more compressed spring that you could stretch out and allow it to work better.
Also take some isopropyl alcohol and a cotton tip applicator and clean the battery contact point inside of the Provari. Also the button top of your
batteries. Any dust, dirt, or carbon deposit on these contact points will interupt conduction.
Check the appearance of the threads on the endcaps. The threads should appear shiny like bare metal. If they are dark or dirty looking, oxidation of the bare metal has begun. This oxidation can disrupt electrical conduction of the battery. If dark with oxidation, you will need some Noalox from your hardware store to remove the dark oxidation buildup. One wouldn't think a new battery cap would have oxidation yet, but who knows how long yours has been sitting in the warehouse waiting to be shipped out? I found my Noalox in the electrical section of Home Depot.
buy the smallest quantity that they sell; a little bit goes a long way and will last you a lifetime
It's a wise idea to have some Noalox on hand anyway. Provape recommends using it on the threads on a maintanance schedule. Failure to use it can cause the threading to lock up. I apply some to my Provari's threads about every month or so to keep the threads "buttery", shiney, and well lubed. In case you can't find this at a hardware, Provape sells it, too.
