Does anyone have the exact size/part number for the correct battery replacement? I believe I will need to change mine pretty soon as it has corroded/started cranking slower.
Thanks in advance!
Everstart Maxx-47 is what fit perfectly in my 07 V.
Whether you are replacing the battery or not, you want to clean off the corrosion. Then you can check the battery connections to make sure they are good and tight. To add to APLPIX's advice; take a large plastic cup, pour some baking soda in it then add water and mix it up good. Pour that on the corrosion areas and it will quickly dissolve. Won't need to wire brush it as much. If you have a servicable battery (you can take off the caps and add distilled water), make sure the caps are tight before the baking soda thing, you don't want any of that getting inside the battery.
To help prevent corrosion from coming back as fast, go buy some of those felt washer things (one is red, one is green) where they sell batteries (approx $1) and some di-electric grease (the grease is sometimes sold in a little packet for approx $1, good for a battery or two). Loosen the clamp holding the wires to the battery, remove the wire clamp from the terminal, make sure it is clean (maybe more water/soda and wire brushing), put the felt washer over the terminals, spread a little di-electric grease on the terminal and put the wires back on, and secure them well. May need to do the same thing with the hold down clamp. Sometimes corrosion will happen where the hold down clamp sits on the battery (common with my Toyotas).
Do this when you install a new battery (felt washer and grease) and you may not have to address corrosion for several years if at all based on my experience.
I have been quoted a price of $75 at a dealership to do the "battery service" thing I described above.
