PRODUCT DETAILS
CHYEAH BOYEEEEEE.
RallySport Direct is happy to carry the Auto Meter Battery Extender. This is a great option for those of you who have a race car or a car that you only drive on Sundays and you need to keep some juice in the battery. Letting your battery drain and frequently jump-starting your vehicle can be hard on your electrical systems and you could even pop a capacitor in your ECU among other things. You can avoid all of this hassle with an appropriate battery tender to keep your battery from completely draining.
On this page, you are looking at the Auto Meter Battery Extender in the 12V/3A option.
Here are the key features:
- Battery extenders keep your battery at full charge on a continuous basis which will maximize battery life
- Compatible with all lead-acid batteries which include standard, AGM, Gel Cell
- Parasitic drain protection
- Fully automatic "smart" charging with advanced circuitry enables efficient and safe charging via Auto Meter's advanced software and digital circuitry
- BEX Series style charger which is fully equipped with sophisticated circuitry that will safely charge and maintain batteries without overcharging. Charging lights will tell you what stage of charge your battery is currently taking
- Indicator lights include AMBER for desulfation, RED for charging, and GREEN for a full charge
- WATER RESISTANT: Bex Series extenders are purpose-built to resist water so you can bring the charger to the source without removing the battery
- Spark-free connection and reverse polarity protection
- 3.0A Charge current
- 12V Battery voltage
- BEX Series chargers are versatile with a compact ruggedized composite shell that makes them safe to set and forget on all of your household vehicles
- Comes with 2 sets of leads which are clamps and ring terminals
- CEC and UL1236 Compliant
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
