how do i unhook battery

i need to unhook the battery while installing a new radio, but its underneath the windshield wiper fluid. do i have to take out that resevoir and bar above it to get to the negative battery terminal?

how do i get to the battery?

The terminals should be on the SIDE of the battery towards the engine. As far as I know, you shouldn't need to remove the resevoir to get to them. You might have to remove the air-box though.

i figured it out eventually, i had to unhook that cross bar and the posts were on the side of the battery.. thanks for your reply though..:)
