510 Cartridge Pen Battery 900mah (x10 Batteries)

Safe, effective mid-grade quality.


This battery is a mid-grade battery with an easy to use USB port for charging. This battery does not require the user to use a pod-style charging port. The cost is a little higher than the pod-style batteries but this unit packs a whopping 900MA in comparison to our entry-level battery that only has 400 Ma.

Button style activation for increased health safety. This style does not allow air to pass through the battery, thereby eliminating any risk of Heavy metal contamination to the user.

With buttonless style batteries, the airflow can pass through solder points in the battery that could be potentially harmful to the user.

This battery is very reliable and has production numbers well into the millions of units. We do not have Testing numbers yet on cycle life but we believe it will be around 300 charges at 90% depleted.

The battery is effective down to 1.2 Ohm. it will not work in Sub Ohm (<1 Ohm). This configuration is acceptable with 99% or greater of all cartridges.

Packaged Size: 5.5 inches tall and 1.25 inches square

Gross Weight/Package: 1.8 ounces

Average life expectancy is approximately 400 charges when charged after 90% depleted.

Product warranty is 90 day full replacement.
