My OEM battery took a dookie Omg itself so I bought a Walmart one to get around til I get a different one. I was looking at the deka etx20l but was wondering if I would have to do anything special to mount it and of there are known problems with it. I live in south Florida so cold cranking apps isn't much of a concern.

Thanks for the help

 

Have you looked to see how your factory battery is mounted? In our R56 the one side of the battery fits into a lip in the battery tray and the other side is clamped to the battery tray. The Deka won't have those lips so you'll have to come up with a different mounting solution. We run the ETX9 (7lb battery) so the ETX20L shouldn't give you any problems.
