It fits the GMRS-210+3 directly and restores transmit and receive capability on GMRS frequencies. Capacity is rated at 13.2Wh and matches the original cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGMRS-210+3 platform fit:\u003c\/strong\u003e\n    The GMRS-210+3 runs a 13.2V Ni-MH stack — a voltage rail that requires matched cell count and a BMS that tolerates the transmit current spike when PTT is pressed. Swapping to a different voltage chemistry will prevent the radio from powering on or will trigger an immediate shutdown on transmit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and PTT-load discharge on the GMRS-210+3 platform. The BMS held stable through the transmit surge and did not trip overcurrent. Cell voltages balanced across the stack within two full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the GMRS-210+3 charger dock:\u003c\/strong\u003e\n    If the dock LED shows a fault on first insertion, remove the pack and wipe the contact strip with a dry cloth before reseating. The dock checks BMS handshake voltage before accepting charge — a marginal contact will cause a false fault even if the pack is within spec.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GMRS-210+3 shuts down the moment you press PTT on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 1.0–1.1V per cell — which puts a 12-cell 13.2V stack closer to 12V at rest. When PTT is pressed, transmit current demand spikes sharply. If the pack hasn't received an initial charge, that voltage sag under load crosses the radio's undervoltage cutoff threshold, and the unit shuts down instantly. This is not a faulty pack. Run one full charge cycle before keying up on transmit. After the first full charge, resting voltage should sit above 12.8V and the radio will hold through the transmit surge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator drops one bar immediately after a full charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GMRS-210+3 reads battery level from a simple voltage-threshold indicator — no fuel gauge chip is involved. A new Ni-MH pack can show surface charge voltage right off the charger, then settle 0.2–0.4V lower within the first few minutes of standby. That drop moves the reading across a threshold, cutting one bar. The pack is not losing capacity — it's stabilising from surface charge to resting voltage. Let the radio sit on standby for five minutes post-charge, then check the indicator. A stable reading above 12.6V under light load confirms the pack is within spec.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426361311322,"sku":"BWCS-ICM700TW-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426361344090,"sku":"BWCS-ICM700TW-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426361376858,"sku":"BWCS-ICM700TW-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM700TW-1.webp?v=1779930808","url":"https:\/\/batteryweb.com\/products\/maxon-gmrs-2103-replacement-battery-132v-1000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
