OptiMate TM71 Weatherproof TM Eyelet Battery Lead

About this Optimate OptiMate TM71 Weatherproof TM Eyelet Battery Lead

Maintain your battery with ease using the OptiMate TM71 Weatherproof Eyelet Lead, available now at On Yer Bike. This is the original permanent connection lead designed for older-style OptiMate and AccuMate chargers featuring the white TM (KET) 2-pin connector. By fitting this lead directly to your battery terminals, you eliminate the need to remove seats or side panels every time your motorcycle needs a charge—making it an essential accessory for commuters and seasonal riders alike.

The TM71 lead features 50cm of high-quality, 18AWG copper cable designed for maximum conductivity. The 1/4” / M6 eyelets are the perfect size for most standard motorbike batteries, providing a secure and vibration-resistant connection. For your peace of mind, the lead includes an integrated 15A fuse, protecting your bike’s sensitive electrical system against potential short circuits.

At On Yer Bike, we recommend the TM71 for its proven durability. The white TM connector is protected by a unique weatherproof rubber shroud and a tethered sealing cap, ensuring the connection points remain free from road grime, moisture, and corrosion. Even in the depths of a UK winter, the cable is rated to remain flexible down to -40°C. If you have an older OptiMate 2, 3, or 4 (pre-2012) or an AccuMate, this is the professional-grade lead you need to keep your machine ready for the road.
