XS Power HD-3100 Hold Down for Group 31 Battery Security
Designed to fit the Group 31 battery footprint precisely, the XS Power HD-3100 Hold Down eliminates the play and rattle that comes with universal battery mounting solutions. Group 31 batteries are a common choice for secondary audio banks in trunk builds and cargo area installations, and securing them properly matters just as much as it does under the hood. A properly held battery protects terminal connections, reduces cable fatigue, and keeps the build looking intentional rather than improvised.
The HD-3100 works cleanly alongside XS Power terminal hardware and ring terminals, completing a matched set of car audio battery hardware that meets the standards competitors and serious daily-driver builders expect. Whether the vehicle is headed to a show, a competition, or just daily street use, the battery should stay exactly where it was installed — and this hold down ensures it does.
