It also fits the SPS802, SPH155, and SPH155DT. Voltage and chemistry match OEM spec — the radio powers on and keys up normally without any firmware modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPS801 \/ SPH155 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, contact orientation, and 7.2V voltage rail. The APX1105 pack slots into all listed variants without modification. No adapter or rewiring needed.\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 pulls on the SPS801 platform. The BMS held stable under transmit current spikes and discharged cleanly to the low-voltage cutoff without tripping into lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the dock:\u003c\/strong\u003e\n    If the charger shows a fault LED on first insert, the pack contacts may not have seated cleanly. Remove the battery, wipe the contact strip with a dry cloth, and reseat firmly. The dock requires a clean contact cycle to register the pack and 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 SPS801 cuts out mid-transmission on a new APX1105 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 1.1–1.2V per cell, which puts the 6-cell pack around 6.6–7.2V. Under the high current draw of a PTT transmit event, that voltage can sag below the radio's TX cutoff threshold before the pack has been fully conditioned. The radio interprets this as a depleted battery and drops the transmission. Running one or two full charge-discharge cycles brings the cells to full capacity and firms up the voltage floor under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator shows one fewer bar than expected after fitting the APX1105\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SPS801 uses a voltage-threshold bar indicator — each bar corresponds to a resting voltage band. A new Ni-MH pack at storage voltage sits in a lower band, so the radio displays one fewer bar even though the pack is not depleted. This is not a fault with the pack or the radio. Charge the battery fully and allow it to rest for 15 minutes off the dock — resting voltage should read 8.4–8.6V and the indicator will reflect the correct level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426346270810,"sku":"BWCS-UPS801TW-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426346303578,"sku":"BWCS-UPS801TW-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426346336346,"sku":"BWCS-UPS801TW-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPS801TW-1.webp?v=1779930784","url":"https:\/\/batteryweb.com\/products\/uniden-sps801-replacement-battery-72v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
