It restores power to collars used for hunting dog training — covering stimulation, beep, and vibration functions. Fits the SR200-I, Sporthunter 1200 SR200-I, Sporthunter 1800 SR200-IM, and Uplandhunter SR-200IB.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSR200-I collar family fit:\u003c\/strong\u003e\n    These models share the same 4.8V four-cell Ni-MH configuration, physical footprint (48.87 × 34.05 × 12.49mm), and connector pinout. The collar's stimulation circuit is matched to this voltage range — going outside it affects output consistency.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles through the SR200-I collar unit. The BMS accepted the charge profile without fault flags, and stimulation output held steady across all intensity levels throughout the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst use after a long collar shutdown:\u003c\/strong\u003e\n    If the collar has sat dead for weeks, the Ni-MH cells may have self-discharged below normal operating threshold. Run a full charge before first use — some units need a second charge cycle before the collar powers on and holds a steady indicator light.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SR200-I collar shows a solid charge light but won't activate\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that have been deeply discharged can hold enough surface charge to trigger the collar's charge indicator without actually recovering usable cell capacity. The collar's microcontroller checks for a minimum voltage threshold before enabling the stimulation circuit — if the pack doesn't clear that threshold under load, the collar stays inactive. This is a cell recovery issue, not a charger fault. Run two full charge cycles back-to-back and check whether the collar responds to the remote after each one.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar battery draining noticeably faster in open or rural terrain\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SR200-I increases transmission power when the receiver collar is at range limit or in heavy cover — the collar and remote handset work harder to maintain signal, which pulls more current from the pack. Ni-MH chemistry also loses available capacity in cold conditions, compressing the usable discharge range further. If drain is faster than expected, check ambient temperature and working distance. For cold-weather hunts, keep the collar on the dog and minimise time sitting powered-on but inactive, which draws steady quiescent current without the pack warming from discharge load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360189120602,"sku":"BWCS-SDC25SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360189153370,"sku":"BWCS-SDC25SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360189186138,"sku":"BWCS-SDC25SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDC25SL-1.webp?v=1778610959","url":"https:\/\/batteryweb.com\/products\/sportdog-houndhunter-sr200-i-replacement-battery-48v-750mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
