You could use a memory saver before you disconnect, anything. Might help. Do you have basic set of wrenches and sockets with several extentions? There is chassis cross-brace across top of battery, remove. Remove negative battery cable then remove positive battery cable. Then you have to remove battery hold-down, you may need long extension for that. On removal don't tip battery more than 40 degrees. I don't have bolts sizes, that is why you need basic set of wrenches and sockets, standard and metric. If your handy under the hood, you shouldn't have any problems.
