NOTE
: Charge batteries daily. It is critical not to let them run low at any time.

: Karma recommends that both batteries be replaced if one battery is defective.
WARNING
：
NEVER allow any of your tools and/or battery cables to contact BOTH terminal posts at
the same time. An electrical short may occur and injury or damage may occur.
CAUTION
：
When tightening the clamps, always use a box or crescent wrench. Pliers will round off
(strip) the nuts. NEVER wiggle the terminal when tightening as the battery may be
damaged.
Remove the batteries and cable assemblies from the scooter.
If necessary, lift the battery terminal insulator/boot off the battery terminal (you will
need a crescent wrench).
Position and secure battery cables onto new battery terminals. Connect the black
cable to the negative (-) terminal. Connect the red cable to the positive (+)
terminal.
