Source 18650 Battery Tube
Free optional polarity engraving
We don’t need to tell you how important it is that your customers put cells in the correct polarity. At best their device won’t work until the battery polarity is corrected. At worst they have thermal runaway.
These 18650 battery tubes as standard have a negative polarity marking inside the tube. If you DO NOT want us to mark them please leave a note at checkout, or email, phone in, message us etc and let us know. Do remember though we’re usually pretty snappy at shipping orders so get in touch as soon as you place your order. Or even before.
“BATTERY NEGATIVE THIS END” Custom internal text is available but will be chargeable.
External 360° engraving and laser marking available
We have a selection of ready to go designs and files for 18650 battery tubes to choose from that we have created in the past, or you can supply your own artwork providing it’s good quality vector art in the correct dimensions.
