Product Description
Shop the Deka AUX18L Battery: Reliable Backup Power for Your Vehicle
When your car's dashboard warnings light up, or the automatic start-stop feature suddenly stops working, a weak auxiliary battery is usually the culprit. The Deka AUX18L 12V AGM auxiliary battery gives your vehicle or hybrid, including models like the BMW i3, the steady backup power it needs. Designed as a direct-fit replacement for Group 404R setups, this AUX18L battery handles heavy electrical loads so your starter battery stays focused on starting your engine.
Frequently Asked Questions
What vehicles use the Deka AUX18L auxiliary battery?
A: This battery is commonly used as a replacement auxiliary power unit in modern luxury vehicles and hybrids, including BMW i3 models, select Mercedes-Benz sedans, and Jeep models requiring a Group 404R or AUX18L size.
What is the difference between an auxiliary battery and a main starter battery?
A: Your main starter battery cranks the engine, while the auxiliary battery powers secondary electrical systems, safety sensors, infotainment, and start-stop functions. This setup prevents your main battery from draining when idling.
What type of charger should I use with the Deka AUX18L battery?
A: We recommend using a battery charger that is compatible with 12-volt AGM batteries. A smart AGM charger can properly regulate the charging process and help avoid overcharging. It’s best to avoid older or unregulated chargers that may overcharge and damage the battery.
Does the Deka AUX18L need to be registered or programmed after installation?
A: If the battery is being placed in a vehicle with an active Battery Management System (BMS), such as the BMW i3, it will need to be registered after installation. Refer to your owner’s manual or service information for your specific vehicle before replacing the battery.
Does the Deka AUX18L have a vent connection?
A: Yes. The AUX18L features a physical vent hole connection. Because this battery is installed in an enclosed space, any gas it releases needs to be safely dispersed through the vent. If you are replacing this battery yourself, ensure you firmly attach the vent tube elbow from your car to the side port of the Deka AUX18L before securing the hold-down bracket.

Customer Reviews
Brand new. Fit right into the battery compartment with no problems. Was chardge and ready to go when it arrived. The price was right. So affordable compared to the oem battery. Seems durable with strong connections. Registered to the car problem also.
This is the one you want. Don't try to 'save a little more' by getting 'about the same thing' because you need it yesterday. You'll just end up spending as much (and twice the time) as the dealer. Ask me how I know...
Price was a bit high but made in the USA and is the exact reaplcement for BMW i3's 12v battery. It even has a hole for the vent tube.
