The Oxford Products Croc-O-Ring Leads offer a clever 2 in 1 design where each ring lead is securely clipped into a crocodile clip, saving the need for two separate wiring harnesses. They provide a fast connection to charge batteries in a car or on the workshop bench. The ring leads can be quickly detached and connected to a battery to provide a permanent charging lead for quick connection to one of the Oxford Oximiser Pro battery optimisers. A heavy-duty all-weather cable is ultra-durable and connects to any battery charger via SAE connector. These have crocodile clips with integrated M6 ring leads with 18AWG all-weather wiring loom, 0.5m length. Supplied with 3 micro blade fuses to work with Oximiser Pro battery optimisers:900/1250 = 2A, 2000 = 4.0A, 5000 = 7.5A.
