12 Volt Auxiliary Battery East Penn Deka AUX18L

12 Volt Auxiliary Battery East Penn Deka AUX18L

Dealer wanted to charge $575 to replace and register the Auxiliary 12 volt battery. Highly recommended by several battery experts to use the East Penn - Deka AUX18L. This battery has a special vent that the ETX18 does not. If you replace it yourself (go to YouTube) you can buy at Remy Battery or any local battery retailer who caries East Penn - Deka for special order. YOU MUST HAVE THE BATTERY REGISTERED by any reputable mechanic. I’ve been able to get the battery for $98 and have it registered to the onboard i3 computer for $65. That just over $160 total where the dealer want close to $600. See this spec sheet from East Penn - Deka

It took me four days of research and conversations with Los Angeles four largest battery retailers and the District Manager at East Penn - Deka to CONFIRM the AUX18L is the only battery you’ll want or risk voiding your warranty.

Just FYI, East Penn Manufacturing makes the original OEM 12 volt battery in the BMW i3 .
The Deka AUX18L IS the original factory i3 12 volt battery in every new i3.

Look at the manufacturer's tag on your OEM i3 BMW battery.

It says "Produzido por E.P.M. Products"
Which translated is Produced by East Penn Manufacturing Products

And check out the address of "E.P.M."on the tag - 1 Deka Rd, Lyon Station, PA 19536

Also, East Penn has warehouse outlet stores in major cities in the U.S. where you can buy the battery over the counter.

Unfortunately, Honolulu isn't one of the cities with a warehouse outlet store, so I had to order the Deka AUX18L from a local Deka retail partner. The best price I was able to get was $150 including shipping to Honolulu. Remy Battery wanted to charge ~$80 for shipping increasing the total cost to over $200. The price at BMW of Honolulu is ~$210. I wish I had been able to buy one for mtkkk45's $98 price, but Honolulu is an expensive place to live, so I paid the "paradise tax".

You didn't do badly - mtkkk45 managed a real deal. Here in Dallas, at the East Penn warehouse store, the Deka AUX 18L battery is about $150 with tax.

Thanks for the info. Just checked with remybattery.com in Milwaukee, they have it for $119.95 with free shipping, $16.11 for FedEx Ground to my location in Cleveland, OH.
There's also a couple local East Penn distributors in the area, who I will also check with when I need a battery.
