Thank you.

You are quite correct the original is stamped wrong.

Did not wish to install it once saw the diffre ce just incase but upon checking new battery it is 100% as should be.

That doesn’t sound right. The best thing to do if you or someone you know has a multimeter is check the polarity to be sure as the +&- might have been stamped incorrectly.
