Two questions:racer7 said:Do get yourself a modern charger with pulse capability. Old style car chargers and many of the 1A maintainers will not initiate a charge on a deeply discharged battery
I use an Xtreme- you can google it- but there are others as well. A while ago I even used my Xtreme to recover a car battery that no other charger in my set could.though its "only" a 3A device.
You may not need a new battery but if you do the BMW Exide isn't a very good choice unless you get a warranty freebie- they've got a history with many. The preferred battery is a PC680 Odyssey- cheaper and far superior especially at cool weather starts.
- does the PC680 Odyssey fit hassle-free in the 2012 RT battery compartment? Is it just plug-and-play?
- can you recharge it, or just tend it over winter, with an Optimate 3 charger?
