Frequently Asked Questions

How does this compare to cigarette lighter memory savers?

Unlike cigarette lighter adapters that can lose connection, the MS4000 plugs directly into the OBDII port for a secure, reliable connection. It also includes its own battery and charger, so you don't need the vehicle's electrical system to be active.

What vehicle settings does this automotive memory saver protect?

This battery memory saver maintains power to anti-theft radio codes, clock settings, keyless entry programming, alarm codes, GPS memory, TPMS calibrations, and other electronic control modules that would reset without constant power.

How long does the internal battery last during use?

The 4.5Ah battery provides several hours of backup power for typical battery replacement jobs. The amber LED indicator warns you when the charge drops below 11.6V, giving you plenty of time to finish the work or recharge the unit.

Will this work on my specific car model?

This auto memory saver works with any vehicle equipped with an OBDII diagnostic port (1996 and newer cars, trucks, and SUVs). The universal OBDII connector fits all standard diagnostic ports without adapters.

All the details are at the bottom of our site under Shipping & Return Policy. You'll find everything about returns, freight damage, and any brand-specific rules.

Most larger items like car lifts and heavy equipment ship free, but depending on the brand there might be freight costs. Smaller items almost always have shipping fees via UPS, USPS, FedEx, etc. We'll show you any extra costs before you check out.

Shipping estimates are just that — estimates, and they're not guaranteed. Weather, freight delays, and carrier issues can throw things off, especially with bigger items. If you're on a tight timeline for installation, it's smart to give yourself some wiggle room.

Yep! Once it ships, we'll email you the tracking info so you can keep tabs on your delivery and plan accordingly.

We always send tracking info once your order ships. If it's been more than five business days and you haven't heard anything, just shoot us a message at support@garagesupplyguys.com or hit us up through the Contact Us page. We'll figure out what's going on.

Just reach out to us after your purchase and we'll connect you with trusted installers in your area. You can negotiate pricing and scheduling directly with them, or we can help coordinate the whole process for you.
