The wiring on the new battery had the opposite polarity to the battery being removed. The red and black wires on the connector were transposed. I emailed support and received assurance that despite polarity being different it should work. It worked. Not sure how, usually when a battery goes in the wrong way nothing happens or something smokes. I happy that a return/exchange wasn't necessary.
