All our 510 thread batteries are the building block of a solid Cannabis oil pen. All are rechargeable by USB, come with a charging port and fit most atomizers or Cannabis oil cartridges. All batteries are tested before shipping and have a 30-day window for replacement of defective batteries after delivery.Less experienced consumers will appreciate the ease of a touch battery. As the name suggests, this battery type allows for simply inhaling without pressing a button. After inhaling for 10 seconds, it automatically shuts off to protect the longevity of the battery. Touch batteries are also a good choice for branding for first time patient specials, giveaways and an introduction to Marijuana oil pens.Slim line batteries offer a slim profile and sleek look, perfect for fitting in a pocket. A flush mounted button allows users to power off and on by clicking this Cannabis oil pens’ button five times.
