FAQs
Can I connect multiple 2.5m cables together?
While technically possible, it is not recommended as it increases voltage drop and potential for poor connections. Use a single extension where possible.
Is this cable waterproof?
The cable is designed for standard workshop and garage environments. While it is durable, it should not be submerged in water or left in standing water.
Will this work with other brands of battery chargers?
This cable is specifically designed for Tecmate OptiMate and AccuMate systems. Compatibility with other brands is not guaranteed.
What is the maximum amperage this cable can handle?
The cable is rated for a maximum of 5A. Do not use it for applications requiring higher current.
Does this cable include a fuse?
This is an extension lead and does not contain an internal fuse. Always ensure your primary charging lead is properly fused at the battery connection.
Troubleshooting
Charger does not indicate a connection
Verify that both ends of the extension cable are firmly pushed together and that the battery lead is properly attached to the battery terminals.
Intermittent charging light
Check the connectors for dirt or oxidation. Clean with a dry contact cleaner if necessary and ensure the connection is not under mechanical strain.

Setup, Compatibility & Care
To set up, simply connect the male end of the extension cable into your charger’s output lead and the female end into the battery connector lead. Ensure that the combined cable length does not create a tripping hazard. This cable is compatible with all OptiMate and AccuMate chargers featuring standard SAE or TM-style connectors. For maintenance, periodically inspect the cable for nicks or exposed wires, and keep the connector terminals free from debris or corrosion using a dry cloth. Avoid pulling on the cable to disconnect; always grip the plastic connector housing.
