yes, with some slight modifaictions
On a Honda Civic I would not buy under a 500 CCA battery. The more the better especially if you live in a cold climate.
Your question is incomplete. You never mentioned what the cca rating is in the spec battery. As long as you put in a battery of equal or larger cca rating, you will be fine.
525 is minimum CCA spec for that van, you can put in a better battery if you want (good idea) up to 800-1000+ CCA. CCA ratings are battery specific and should be on the battery tag. So that meads if someone put a Honda battery in it you may only have a 300CCA battery in it.
Group size 34, CCA 600 or if you are living in a colder climate, CCA 800.
Yes, it should be sufficient.
Group size 34/78 800 CCA will work fine.
With the 5.7 engine, group size 34/78 800 CCA.
The Mercury Optimax requires a 12 volt starting battery, rated @ 800-1000 cca.
Look on the battery and see who made it. It really does not matter who produced the battery. You can install any brand battery you want as long as it fits and you get one with the correct CCA rating. If you want an OEM battery then buy one from your Honda dealer.
First off you do not have to buy a 532 CCA battery. Any battery that fits your car with a CCA rating close to 532 CCA or above will work just fine. Walmart sells an excellent battery that will be more than 532 CCA. The more CCA the better.
Yes, but remember the more CCA the better especially if you live in a cold climate.
