It fits the compact form factor used by security, hospitality, and commercial radio users who run these devices through full shifts. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSV10 \/ SV11 \/ SV21 platform compatibility:\u003c\/strong\u003e\n    These models share the same battery bay geometry, contact layout, and 7.2V nominal voltage rail. The BMS handshake threshold is consistent across the series, so one pack covers the whole fleet without connector modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge, standby, and transmit loads on the SV10 platform. The BMS handled PTT-triggered current spikes without tripping into overcurrent lockout, and cell voltage recovered cleanly between transmissions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    If the charger dock shows a fault LED when you first seat this pack, remove it, wipe the gold contact strip with a dry cloth, and reseat firmly. The Sprint dock requires a clean contact cycle to complete the BMS handshake before it will begin charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SV10 cuts out mid-transmission on a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at partial storage voltage — typically 6.0–6.4V on a 7.2V pack. When PTT is pressed, transmit current demand spikes sharply. At storage voltage, internal resistance is higher, so the voltage sag under that spike can breach the BMS low-voltage cutoff threshold even though the pack is not depleted. The radio cuts out not because the battery is faulty, but because it has not yet been fully charged. Run one complete charge cycle before the first shift and the cutout behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator reads one bar fewer than expected after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SV10 series uses a simple voltage-threshold bar indicator — each bar corresponds to a voltage band, not a tracked charge percentage. A new pack at storage voltage sits in the lower threshold band and displays fewer bars immediately after insertion. This is not a cell fault. Charge the pack fully to 7.2V nominal and the indicator will step up to the correct bar count. No reset or calibration is needed on the radio itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426369699930,"sku":"BWCS-MTP10TW-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426369732698,"sku":"BWCS-MTP10TW-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426369765466,"sku":"BWCS-MTP10TW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTP10TW_1.webp?v=1779931027","url":"https:\/\/batteryweb.com\/products\/sprint-sv10-replacement-battery-72v-1000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
