Can it be used as a dual battery isolator?

It is sold as a dual battery isolator, but no continuous current rating is published. Isolators carry charging current for long periods, so confirm the contact rating before relying on it.

What vehicles does it fit?

No fitment list is given. Match the terminal layout and mounting size to the relay you are replacing, and check the coil voltage is 12V.

What are the dimensions?

The housing measures about 7.7 by 4.8 by 7.8 cm. Measure your mounting space before ordering.

Does it come with a wiring diagram?

No wiring diagram or terminal labeling is provided. Trace your existing relay wiring before removal.

Is it a continuous-duty relay?

That is not stated. For isolator use where the relay stays energized while driving, a continuous-duty rating matters.

Our take on the HINTRMENT 12V Starting Relay Power, Dual Battery Isolator

The HINTRMENT 12V Starting Relay is a plastic automotive relay housing sold as a dual battery isolator and starter relay replacement. It is a small black block roughly 7.7 by 4.8 by 7.8 cm. The listing gives no coil current, contact rating, terminal layout or wiring diagram, so a buyer cannot confirm it suits a given vehicle or dual-battery setup from the information provided. Compared with branded isolators that publish amp ratings and install guides, this is a low-information generic part best treated as a spare only after checking the terminals match.
