Ask them for specifics - like an Amphenol series name and part number (probably numbers - there may be one for the shell, another for the contact, etc.). I say "Amphenol," because that's how they refer to it in their product literature. But maybe they're lying and it's a proprietary Chinese connector which uses a RADSOK like contact. Their data sheets are worthless - they don't give any specifics on one of the most fundamental parts of a battery - how to connect to it. If it is a proprietary connector, they're probably using it as another profit center, and I wouldn't hesitate to return the battery - that's customer hostile.
