The APX1105 pack slots directly into the battery bay and powers both transmit and receive operations across these models. All four share the same voltage rail, connector footprint, and BMS handshake protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPS801 \/ SPS802 \/ SPH155 platform compatibility:\u003c\/strong\u003e\n    These models run the same 7.2V Ni-MH architecture with an identical connector and contact arrangement. The BMS in each radio uses the same voltage-threshold acceptance window, so one pack services the full lineup without modification.\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 discharge on the SPS802 platform. The BMS accepted the new cell voltage without fault, and the radio held transmit current without dropping the BMS protection circuit during sustained PTT.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip reset on first dock insertion:\u003c\/strong\u003e\n    If the charger shows a fault LED on the first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Uniden dock requires a clean contact cycle to register the new pack's BMS state before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SPS801 cuts out mid-transmission on a new APX1105 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage — typically 1.0–1.1V per cell, which puts a 6-cell 7.2V pack around 6.2–6.6V before its first full charge. The SPS801's BMS trips the protection circuit when transmit current draws the pack below its undervoltage threshold. This is not a faulty pack — it is the BMS responding correctly to a cell that has not yet been charged to operating voltage. Charge the pack fully in the dock before the first use and the cutout will not recur.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after inserting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SPS series uses a simple voltage-threshold bar indicator — each bar maps to a voltage band, not a fuel calculation. A new pack at storage voltage reads one band lower than a fully charged pack, so the display shows one fewer bar even though the cell is not depleted. After a full charge cycle the resting voltage rises to 7.2–7.5V and the indicator steps up to the correct level. No hardware fault is involved — run one complete charge cycle in the dock and recheck.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426345812058,"sku":"BWCS-UPS802TW-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426345844826,"sku":"BWCS-UPS802TW-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426345877594,"sku":"BWCS-UPS802TW-3","price":84.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPS802TW_1.webp?v=1779930784","url":"https:\/\/batteryweb.com\/products\/uniden-sps801-replacement-battery-72v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
