This battery fits all Tomos electric start mopds. If the battery you have has a "4" somewhere in the part number, Then this is battey which will fit.
For Tomos Nitro scooters use Bat7. See other battey on this website. This is a very good quality battery.. Unfortunately the original Tomos batteries are not as good as this battey
You have to add included acid. This way you get a fresh battey. Simple to do, read safety instructions first.
