It replaces OEM part numbers 1272800 and 1281100 Rev.B. The cell pack matches the original voltage rail and connector orientation for the G3 platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG3 platform compatibility:\u003c\/strong\u003e\n    The G3 Field, G3 Pro, Classic 70 G3, and Field 90 G3 all run the same 7.2V Ni-MH cell configuration and share an identical BMS handshake and connector footprint — which is why one battery covers the full G3 lineup and several related models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a G3-series collar and confirmed the BMS accepted the charge sequence without interruption. Charge termination triggered cleanly at full capacity with no delta-V errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use collar activation:\u003c\/strong\u003e\n    After installing, power on the collar and allow the transmitter-receiver link to re-establish before testing stimulation levels — the G3 system rechecks the receiver's power state on first boot and may need 30–60 seconds before the remote registers a paired connection.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the G3 collar stops responding mid-session in cold weather\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells lose usable voltage faster in cold temperatures — internal resistance rises, and the pack can drop below the collar's minimum operating voltage even when the cell isn't fully depleted. The G3's protection circuit reads this as a low-battery condition and cuts output to the receiver. Warming the collar briefly before a session helps, but a cell pack with degraded capacity will hit this threshold sooner than a fresh one. If cold-weather dropouts are frequent, the cell pack has likely lost enough capacity that voltage sag under load is exceeding the collar's cutoff threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eG3 collar powers on but transmitter shows no link after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a re-pairing issue, not a battery fault. When the G3 receiver loses power completely — as it does during a battery swap — it exits its stored link state and waits for a fresh handshake from the transmitter. Power both the collar and the handheld transmitter off fully, then power the transmitter on first, followed by the collar. If the link still doesn't establish, hold the collar's power button for 8–10 seconds to force a full reset before repeating the pairing sequence.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360178798682,"sku":"BWCS-STD30SL-1","price":13.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360178831450,"sku":"BWCS-STD30SL-2","price":14.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360178864218,"sku":"BWCS-STD30SL-3","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-STD30SL_1.webp?v=1778610961","url":"https:\/\/batteryweb.com\/products\/tri-tronics-g3-field-replacement-battery-72v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
