Replacing the Battery on a Sym Maxsym 400

Model: Sym Maxsym 400
Part: Battery

Video tutorial

The battery is located in the compartment under the ignition key hole (this cover also needs to be opened with the key). At this point, unscrew the two cross-head screws on your right and open the second cover. It's not over yet, as you will now find two additional screws to remove, this time using a socket spanner: these secure the metal bracket holding the battery in place.

Pull the battery out enough to unscrew it, then disconnect the two bolts for the negative and positive terminals (always remove the negative first), remove the battery itself, and fit the new one.
