Antigravity AT7B-BS 12V Hustler Raptor XD & Dash XD Battery 180CA (w/ Re-Start)
Antigravity AT7B-BS 12V Battery for the Hustler Raptor X, XL, XD, XDX and Dash XD: Lithium in the 607723 Case
The smaller Hustler zero turns do not take the Group U1 or U1R that the Raptor SD and the Fastrak use. The Raptor X, XL, XD and XDX, the Dash XD and the Surfer Pro start on Hustler part 607723, a thin 12V 9Ah AGM about 5.95 x 2.56 x 3.70 inches with bolt terminals, rated 120 to 140 cold cranking amps. The Antigravity AT7B-BS RE-START is that thin case in lithium: 5.75 x 2.5 x 3.75 inches, 180 cranking amps, 1.5 lbs.
Zero turns sit between cuts and all winter, and a small lead-acid battery that sits goes flat. The AT7B-BS is a RE-START battery: before a slow drain can run it flat, its BMS puts it to sleep with a starting reserve held back. Press the button on top, turn the key, mow.
Why the AT7B-BS in your Hustler
- Within 0.2 inch of the 607723 in length, width and height, so it drops into the stock tray
- 180 cranking amps from 1.5 lbs
- RE-START reserve and push-button jump start
- 4-terminal design fits either cable layout; mount in any orientation
- Holds its charge through the off-season; no tender required
- Full BMS: over-charge, over-discharge, thermal protection, cell balancing

Fits the Hustler Raptor X, XL, XD and XDX, the Dash XD and the Surfer Pro, the models that take part 607723. It stores less energy than the 9Ah original (3.3Ah of lithium, rated as a 7Ah lead-acid equivalent). Starting takes only a small part of that, the mower's charging system puts it back as you mow, and the RE-START reserve covers the day it runs down. The Raptor SD and SDX take a Group U1R (Hustler's manual calls for 225 or more cranking amps) and the Fastrak a Group U1; those batteries are on our Hustler mower battery page. Check the part number on your old battery, and if you are not sure, we will confirm fitment before you order.
Your mower's charging system keeps it topped up as you mow. For storage, any 12V charger with a lithium (LiFePO4) mode works; a lead-acid tender with a desulfation setting is hard on lithium cells, so retire the old one.
