What 510 thread means, and what fits a 510 battery

510 is a thread size, not a brand. Wulf Mods puts it simply: if a cart screws onto your battery, “it’s likely a 510 connection.”

Where the name comes from

Nobody agrees. Wulf Mods says “The name comes from 10 threads with 0.5mm spacing.” Helio Supply’s guide to stick batteries says it’s named “510” because “it has 5 threads with a 10mm diameter”. Either way, it doesn’t change what fits. Helio calls 510 “the standard threading used in most vaping devices”.

Not every 510 thread is the same length

LOOKAH gives one case where a 510 part won’t sit right. Its 510 quartz wax carts “do not work with the Seahorse range of devices as the length of the 510 thread is more than the 4mm compatible depth for them.” So even when the thread size matches, the length can matter.

What carts each battery takes

The thread will fit. What to check is the cart’s size and resistance. These are each maker’s own numbers, in grams or milliliters, however the maker gives them.

Battery Carts, in the maker’s words Resistance
Helio Supply Smart Bar Pro 0.5 to 3.5 ml Above 0.8 ohms
Helio Supply Smart Range All 510 threaded carts 0.8 ohms or more
Helio Supply Dual Charge V3 All 510 threaded carts Not stated
LOOKAH Cat 0.5 g to 2 g Not stated
LOOKAH Snail 2.0 Up to 1 ml, and wax atomizers 1.0 to 9.99 ohms
Smyle Labs Penjamin Cart Pen 0.5 g to 1.0 g Not stated
Smyle Labs Car Key Penjamin Up to 1 g Not stated
Smyle Labs Lip Balm Cart Pen 0.5 g and 1.0 g inside; any size on top Not stated
Smyle Labs Inhaler 0.5 g to 1.0 g Not stated
Ooze Quad 510 carts Not stated

Battery size, voltage and charging for each one are in the 510 battery table.

Don’t overtighten the cart

Helio Supply’s guide to the atomizer error says “Screwing in a cart too tightly can actually push down the center pin, making it harder for the battery to make contact.”

Battery size and how long it lasts

Battery size is the number in mAh. Helio Supply says “A higher capacity battery will last longer between charges, but will also be larger and heavier.” The batteries we carry run from 300 mAh (the Car Key Penjamin, going by our listing) to 750 mAh (the LOOKAH Cat).

Other things that screw onto a 510 battery

A 510 battery can run more than carts. This hot knife tip screws on in place of a cart, and its listing says it fits “most standard 510 thread batteries”.
