My battery lasted 6.75 yrs and still cranked day i replaced
Cooltech's Float Charger allows an external connection to the battery, which I find to be the best solution. The connector is mounted behind one of the vertical bars in the grill, using existing hardware, and there is a connector pin cover to keep them clean when traveling. To route the wire properly takes a bit of work, involving dropping down the splitter, but allows for an elegant solution which appears OEM.
