I expect my sigelei Zmax Telescopic to last two years or more. I base this on my experience with the E-Power 14650 I owned before. That is another well-built Chinese APV. I used that tube mod every day for 18 months before upgrading to the Sigelei. I went through a couple of sets of 14650 batteries with it. Over two years later the E-Power 14650 still works fine.
For the eight months I've owned the Sigelei Zmax V3 Telescopic Flat Top I have been using two 18650s, four 18500s and four 18350s. All are IMR batteries. I use the the 18500s most often and hardly ever use the 18350s. Capacity is starting to drop on the 18500s and I will be replacing them soon.
After misplacing the Sigelei for a few hours over the Thanksgiving holiday I decided I needed another for a back-up unit. I provided a mini-review of it here.
