MikeB- I have an Expedition on order, so haven't yet selected an Antigravity model to fit, but have run them on other bikes, and have been very happy with their performance, weight, and size.
Thanks for posting the Antigravity model number! Let us know if you get one, and how it fits.Many thanks @ECJJCE for your response. I've had great experiences with Shorai lithium batteries on previous bikes. However, I do like the re-start concept. I chatted online with a rep from Antigravity who stated that the Antigravity ATZ10 RE-START Lithium Battery is the correct model for the Norden. I noticed that my dealer carries them so I'll get a price from them the next time that I drop in.
What model did you get?Antigravity batteries are 15% off right now through 3/18/23 using coupon ADVRIDER at checkout. I just ordered one. I'll provide an update with how it fits.
I've owned 3 of those Antigravity batteries and they have all been awesome, it's really nice to be able to start after months of sitting without a trickle charger.The Antigravity ATZ10 RE-START Lithium Battery fits perfectly. The footprint is near identical, but it's slightly shorter than the OEM battery. However, the 2 foam spacers that came with the battery were perfectly sized to stick on top of it to hold it in place. Typically you would put the foam spacers underneath the battery, but in this case it was necessary to stick them on top to accommodate the indentation in the bracket.
In terms of weight, the OEM battery is 3,509 grams and the ATZ10 is 972 grams, resulting in a savings of 2,537 grams (or 5 lbs 9 oz). The weight savings were a bonus as I have a preference for Lithium batteries and really like the insurance policy of the Re-Start functionality.
