Stop wrestling with battery clamps every time you want to connect your charger or maintainer. The RTA2415 bolts directly to your battery posts and gives you a permanent, fused SAE quick-connect point -- so plugging in your BatteryMINDer charger takes seconds, not minutes. Sized for standard RV, marine, and automotive batteries, with a 15-amp inline blade fuse protecting your wiring and your battery.
The RTA2415 is a bolt-on ring terminal harness designed to stay on your battery full-time. The negative ring terminal fits the standard 5/16" post stud and the positive ring terminal fits the 3/8" post stud -- matching the industry-standard sizing used on virtually all group 24, 27, and 31 lead-acid, AGM, and gel batteries common in RVs and boats.
A 24-inch 18AWG lead gives you enough reach to route the cable out of a battery compartment or to a pass-through, while the SAE quick-connect plug and protective dust cap stay accessible. When you need to charge or maintain, simply pull the cap and plug in -- no tools, no clamp corrosion, no terminal damage.
5/16" ring for the negative post, 3/8" ring for the positive post -- matches standard RV, marine, and auto battery hardware.
Replaceable standard blade-type fuse protects the circuit during charging and maintenance. Easy roadside swap if a fuse ever blows.
Industry-standard SAE 2-pin polarized connector mates with BatteryMINDer charger leads and most aftermarket SAE accessories. Dust cap included.
Enough length to route out of enclosed battery compartments. 18AWG wire is rated for the 15-amp continuous duty of this harness.
Many RV and boat owners leave their BatteryMINDer charger connected for extended storage periods -- weeks or months at a time. Repeatedly attaching and removing alligator clamps accelerates terminal corrosion and risks accidental shorts. The RTA2415 eliminates that problem by providing a dedicated, fused, polarized connection point that stays put.
The SAE connector is also compatible with most solar charge controller pigtails and other SAE-terminated accessories, making this a useful permanent harness even if you rotate between multiple charging devices.
The RTA2415 is the standard ring terminal harness for the BatteryMINDer line of battery chargers, maintainers, and desulfators. It is the permanent-mount alternative to the standard alligator clip leads included with most BatteryMINDer units. Models in the BatteryMINDer 128CEC1, 2012AGM, 244CEC1, and similar series all use the same SAE 2-pin connector this harness terminates to.
The SAE connector is also compatible with most Battery Tender, NOCO Genius, and other SAE-output charger leads -- making this a broadly useful harness even outside the BatteryMINDer ecosystem.
