Squeeze the clip at the top of the battery compartment and pull back to remove the cover.
Pull the battery out of the compartment.
Pull the old battery off of the battery terminals.
Snap the battery terminals onto the terminals of the new battery. The terminals are two different sizes, making it impossible to connect the battery backwards.
