Note: Any good battery charger now will have 3 or 4 stages of electronically-controlled charging for a discharged battery, with the finishing voltage usually somwhat higher and the current lower.
The aternator has a high charge rate, so it gets you back to 85% quickly. If you are going to let it sit for several days, a trickle charger in the power port will bring it back up to 100%. I use a Battery Tender and the Sears 12V/2amp battery maintainer.
I have read (forget where) that the spiral-wound Optima batteries require a different charging regime than standard lead-acid types. Some alternator voltage regulators will not bring them back up and the battery appears to be dead after only a short service life. However, the anecdotal stories claim that it can be bought right back with the right charging technique. Don't know for sure, so I went with a DieHard Gold (Group 94R) battery. Several of the emerging electronic gremlins disappeared after the battery changeout (after all, it was the factory OEM and 5.5 yrs old).
