If anyone was stuck waiting for a Big Crank ETX20L battery (AKA Deka) from BatteryMart.com, you can get it at your local Advance Auto Parts. Their Autocraft Powersports battery is identical to Big Crank. I've been on backorder from BatteryMart since 17 Mar and they keep extending. Did a parts search at Advance Auto and voila...see for yourself.

Advance Auto: http://shop.advanceautoparts.com/p/a...000%7CL3*15603

Also, Advance Auto has a "20% off" sale (in-store coupon and online) so it's pretty close to BatteryMart's price.

Maybe to some this is old news, but loads of new members/Sportster owners who might not know Deka's many "names/brands." The ETX20L pretty much fits all Sportsters (http://www.dekabatteries.com/assets/base/0278.pdf).

Enjoy!

 

FYI fitment caution:
The ETX20L battery above fits the 03 and earlier Sporty. 2004 and later Sporties take a ETX14L. The ETX20L with its 320CCA is ~7/8" wider than the ETX14L battery.

 

Ah...good catch and correction charley. Advance Auto does have both, but forgot the 03 to 04 change transition - thanks!
