We were wondering about the legality of an Enersys NP18-12BFR battery under rule <R04>. The rule only specifies that the battery be an "EnerSys NP 18-12 battery", but the one that came in the Kit of Parts was an EnerSys NP 18-12B so we wanted to check and make sure this battery would be legal.
The FR in the model number stands for Flame Retardant case and the two batteries share the same Data Sheet as shown here:
