Connector Types

From 2000 to 2012, all UK supplied OptiMates were fitted with TM (AKA “KET”) connectors. In 2012, the SAE connector was introduced.

 

The easiest way to distinguish between the two is to look inside the rubber casing. The TM version has a white connector, while SAE versions are black. 

OptiMate Connector Options


Eyelet terminals – OptiMate offers permanent battery leads with Dual Ring Technology that allows fitment to two different sizes.

M6 - 8, found on the O1 permanent battery lead.
M8 - 10, found on the O11 permanent battery lead.


SAE – OptiMate 2-pin SAE connectors fit all other standard SAE 2-pin connectors. It is a commonly used battery charger connector.


Auto Socket - 12V power outlet socket used in automotive, marine, truck and some motorcycle brands. 

The spring loaded blades of the plug apply pressure to the inside of the socket barrel. 


BIKE socket – 12V power outlet socket used on most motorcycles. Also known as a DIN, Hella or Powerlet connector.

 

Security of connection is high – the dual pincer blades within the socket grips the bevelled (positive) pin of the plug, further aided by the spring loaded negative (ground) terminal of the plug applying pressure against the inside of the socket barrel.


DC 2.5 plug / socket – A commonly used heated apparel in-line axial connector.

 

Security of connection is provided by spring-loaded blades within the jack’s plug that presses against the pin of the receiver. The connection can be easily broken if pulled apart, an advantage for heated gear applications.


OBDII – Diagnostic connector in automotive / truck applications. Low current (< 2 Amps) charging & maintenance is acceptable.


TM / KET – a legacy connector used in OptiMate battery chargers up to 2012.


Ducati (Euro4) – Diagnostic connector in Ducati motorcycles. Models from 2021 will use the Euro 5 motorcycle connector. Up to 5A charging & maintenance is acceptable.


MV Agusta (Euro 4) – Diagnostic connector in MV Agusta motorcycles. Models from 2021 will use the Euro 5 motorcycle connector. Up to 5A charging & maintenance is acceptable.


Euro 5 – Diagnostic connector used in most European made motorcycles from model year 2021. Up to 5A charging & maintenance is acceptable.


Panel mount connections.


Battery clips - connect directly to the battery terminals. This method is safest if the battery is out of the vehicle. OptiMate clips are designed to securely connect to square, round and flat terminals.
