{"title":"Dog Collar","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA GPS dog collar or training collar with a dead battery is a collar that isn't doing its job — and depending on your dog and your situation, that gap in coverage matters more than most pet owners expect until it happens. Whether it's a GPS tracker that stops reporting your dog's location, a bark collar that goes offline mid-day, or a remote training collar that loses connection in the field, every one of these devices depends on a battery that stays charged and holds its capacity through real daily use. Dogs don't take days off, and the collars keeping them safe and trained shouldn't either.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWe carry replacement batteries for a wide range of smart dog collars and pet safety devices including GPS tracking collars, e-collars, bark collars, remote training systems, and invisible fence receiver collars from the brands serious pet owners and hunting dog handlers trust most — Garmin, SportDOG, Dogtra, PetSafe, and more. Whether your dog's GPS tracker is losing battery life too fast to keep up with an active hunting dog in the field, your bark collar isn't lasting through the day anymore, or your invisible fence collar needs a fresh cell to keep your dog safely within boundaries, finding the right replacement here is quick and straightforward. Keep your dog's collar powered, keep your dog where he belongs, and never let a dead battery be the reason your pet goes missing.\u003c\/p\u003e","products":[{"product_id":"dogtra-transmitter-280c-replacement-battery-37v-450mah-li-polymer","title":"Dogtra Transmitter 280C Compatible Battery 3.7V 450mAh","description":"\u003cdiv class=\"bpw-desc\"\u003e\n  \u003ch2 class=\"bpw-desc-h2\"\u003eDogtra Transmitter 280C \/ Transmitter IQ — 3.7V Li-Polymer Replacement Battery (AE562438P6H)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis 3.7V 450mAh lithium-polymer battery fits the Dogtra Transmitter 280C and Transmitter IQ handheld remote units.
