Antigravity Products Register Online


Lithium Starter Batteries and Micro-Starts must be registered within the first 30 days from original purchase date, or original purchaser must provide copy of original receipt or purchase invoice, to be eligible for a warranty claim. Please be sure to read & understand our WARRANTY CONDITIONS prior to submitting the Product Registration Form. Thank you.

Other Antigravity products such as our Electronics and Accessories have a 1-year warranty and do NOT need to be registered. You’re all set!

The Registration form is NOT for Warranty Claims.

Locating Serial Numbers

All Micro-Starts (Except SPORT model): please submit both serial numbers if there are two.

  • One number is on a square hologram sticker, found on the unit’s side.
  • Another serial number has an “AGB” prefix – it is a white label found on unit and/or box.
  • Put “NA” for second serial if only one number is present.

SPORT: please put “NA” in the form’s serial number fields.

CONFIRMATION: once you submit the form a confirmation notice will appear below the send button. You will also receive a Confirmation Email.


All fields are required unless otherwise specified. For logged-in customers, some fields will be conveniently auto-filled using basic info from your account here, but you may edit it.
