{"product_id":"battery-tender-081-0069-6-ring-terminal-harness-12v","title":"Battery Tender Ring Terminal Harness with Quick Disconnect, 12V","description":"\u003cp class=\"nvn-hero\"\u003eBattery Tender's ring terminal harness bolts straight to your 12 volt battery and gives you a 2-pin quick disconnect for easy trickle-charging. The 24 inch lead routes out of the battery box to a dry, reachable spot, and a built-in 7.5 amp fuse protects the wiring. Snap your maintainer on, walk away, and keep your battery topped off all season.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you keep a boat that sits between trips, you already know the drill. You come back after a couple of weeks, turn the key, and the battery's flat. This little harness from Battery Tender fixes that for good. It bolts right to your 12 volt battery posts and gives you a clean 2-pin quick disconnect you can leave hanging in a dry corner of the bilge or lazarette. When it's time to top off the battery, you snap your maintainer onto the plug and walk away. No fumbling with terminal clamps, no cracked knuckles reaching into a tight battery box.\u003c\/p\u003e\n\u003cp\u003eThe pigtail runs 24 inches from the battery to the connector, which is enough to route the plug out of the battery box and up to an accessible spot on most center consoles and small runabouts. The leads are color coded black and red so you won't second guess polarity, and there's a 7.5 amp inline fuse built into the harness to protect the wiring if something ever shorts. The ring terminals slip over standard battery posts and snug down under the same nuts that hold your cables.\u003c\/p\u003e\n\u003cp\u003eHere's how we like to rig it. Mount the ring terminals to the posts first, red to positive and black to negative, then route the 24 inch lead to a dry, reachable spot. A lot of folks tuck the quick disconnect just inside a hatch or up under the console where salt spray can't get at it. That one habit does more for connector life than anything else. Salt air is hard on any exposed contact, so a dab of dielectric grease on the pins and a cover over the plug when it's not in use will keep it clean for years.\u003c\/p\u003e\n\u003cp\u003eThe 2-pin quick disconnect is the same style Battery Tender uses across its maintainer line, so if you've already got a Battery Tender charger in the garage it'll click right on. Leave the harness bolted to the battery all season and just plug in whenever the boat's on the trailer or the lift. That's the whole point of a permanent mount. You set it once and forget the terminals ever existed.\u003c\/p\u003e\n\u003cp\u003eWe sell a lot of these to folks who winterize. Pull the boat in the fall, plug in a maintainer, and come spring the battery's still holding a full charge instead of sulfating away on the shelf. It's just as at home on a bass boat's cranking battery, a pontoon's house bank, or a sailboat sitting on a mooring between weekends. Anywhere a 12 volt battery sits idle and you want it ready to go, this harness earns its keep.\u003c\/p\u003e\n\u003cp\u003eA couple of real-world notes worth knowing. The harness fits Group 24 and Group 27 batteries cleanly, which covers most starting and deep-cycle setups on trailerable boats. If you run AGM batteries with tall hold-down brackets, check your clearance before you tighten everything down, since the ring terminals add a little stack height under the nut. And if your battery bank lives way up in the bow or back at the stern, 24 inches might come up short. That's an easy fix. Splice on a length of marine-grade wire to reach, and keep the fused end near the battery.\u003c\/p\u003e\n\u003cp\u003eOne thing to keep an eye on. The built-in fuse is rated at 7.5 amps, which is plenty for trickle-charging and battery maintenance. If you're running a higher-output charger, watch that fuse, and don't be surprised if you need to step up the inline protection to match your charger's rating. For straight maintenance duty, though, 7.5 amps is right where it should be.\u003c\/p\u003e\n\u003cp\u003eThis is one of those cheap parts that makes owning a boat less annoying. Wire it in once, and keeping your battery healthy over the off-season becomes a ten-second job. Snap on, walk away, snap off before you launch. Simple.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e24-inch lead routes the connector out of the battery box to a dry, accessible spot\u003c\/li\u003e\n  \u003cli\u003e2-pin quick disconnect plug matches the standard Battery Tender maintainer connector\u003c\/li\u003e\n  \u003cli\u003e7.5 amp inline fuse protects the wiring during charging\u003c\/li\u003e\n  \u003cli\u003eRing terminals bolt permanently to standard 12 volt battery posts\u003c\/li\u003e\n  \u003cli\u003eColor-coded black and red leads make polarity obvious at a glance\u003c\/li\u003e\n  \u003cli\u003ePermanent mount design lets you leave it wired in all season\u003c\/li\u003e\n  \u003cli\u003eFits Group 24 and Group 27 batteries cleanly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Battery Tender reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the Battery Tender 081-0069-6 harness actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt bolts permanently to your 12 volt battery posts with ring terminals and gives you a 2-pin quick disconnect plug.
