RetroSound Exile® EX-1 Battery Keeper™
4-stage battery charging system
Our take on the RetroSound Exile® EX-1 Battery Keeper™ by Crutchfield's Bob Bihlmayer
Keep your battery ready
It's great to drive your classic car every day. But if your car gets saved for special occasions, you may need a way to maintain your battery's charge at the proper level and a powerful battery charger.
Not just a charger
Designed with vintage and classic vehicles in mind, the Exile EX-1 Battery Keeper from Retrosound is perfect for anyone who doesn't drive their vehicle every day. It offers four charging stages:
- a diagnostic stage that reads battery status and starts the process with a gentle charge;
- a primary charge stage that charges the battery up to 90% capacity;
- a finishing charge stage that brings the battery up to 100% capacity;
- a “battery keeper” stage, which maintains a healthy charge.
This versatile charger works with 6-volt and 12-volt systems, and charges AGM (gel cell) and standard/maintenance-free batteries. You'll enjoy longer battery life because the "battery keeper" stage monitors the charge level continuously and automatically maintains the battery at a safe, normal level without any over-charging that can shorten battery life.
The dust- and water-resistant Battery Keeper can be mounted permanently next to the battery in almost any vehicle. When you're ready to drive, just unplug and hit the road. If you forget to plug it back in when you get home, the EX-1's low backcurrent drain means it won't run down your battery. It's also designed for safety, with reverse polarity protection, short circuit fault protection, and “no spark” technology to help take the danger out of attaching it to your battery.
Two quick connect harnesses—one with battery clamps and one with O-rings—are included with the EX-1, along with a handy storage bag. You'll have everything you need to keep your ride ready for the road and enjoy the security of knowing that your baby is ready for a drive whenever you are.
You can also purchase this battery charger in a package with a battery monitor.
