I believe the factory battery on my 2007 is failing again, and I am wondering what aftermarket brands owners have tried. I plan to get the battery and alternator tested Friday. In the meantime, I am looking into a better aftermarket battery.
I have an aftermarket stereo, and during the week I only do city driving. The average length of a trip between starts is less than 5 miles, so I am thinking I may not be charging the battery completely during the week. Any suggestions? Are there stronger, yet lighter, batteries that fit in the stock location? Is it worthwhile to fabricate a new mounting bracket for a bigger battery?
All suggestions are appreciated!
