Identify 2 pin connector

[Doug99]

Hi All
I have a bit of old kit which has a rechargeable battery, but I have no charging lead.
Can anyone identify the connector from the attached pics?
Its a 12v battery I'm charging.
The OS diameter of the connector is approx 15mm.
Its a screw in type, not bayonet.
Cheers All
Doug

Spot on shippers.
Its an underwater portable ROV I'm fixing up so the waterproof connector is as showing on your link,
Cheers

Just checked again. My socket has a keyway between pins 1 and 2, but the diagram in your link shows no key.

Edit - I've ordered it as the data specs appear to match my own. Will see what turns up

https://cpc.farnell.com/mbs-connect/sp1310-p2iic/circular-plug-2-pole-5-8mm-ip68/dp/CN21307 looks to have the keyway to my eyes
https://www.farnell.com/datasheets/3165736.pdf may help with measurement checks.

Assuming the aliexpress item is not suitable. Other suppliers of SP13 connectors are available.

The 2 pin one in the photo appears to have locating slots and pegs so that you can only install it with the polarity being one way round.
