It replaces OEM part BBTY0405001 and fits directly into the handset battery compartment. If your handset dies mid-call or won't hold a charge between cradle sits, this is the part that fixes it.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1711 \/ 1721 \/ 1731 \/ 1733 compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, 3.6V Ni-MH chemistry, and connector orientation. The base station charges at a voltage profile matched to this cell type — swapping in a Li-ion pack here would trigger a charging fault. Stick to Ni-MH.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the 1711 handset platform. The BMS accepted the pack without error lights, and the base station initiated trickle charge correctly after the initial full charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base cradle for a full 16 hours before use. Ni-MH cells ship in a partially discharged state — a slow first charge lets the cells reach rated 2000mAh capacity. Cutting this short means the first several cycles will feel short.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells don't hit rated capacity straight out of the box. For the first three to five charge-discharge cycles, the chemistry is still activating and the cells will underperform. This is normal — it is not a fault with the battery. Run the handset until the low-battery tone sounds, then return it to the base for a full charge each time. By cycle five, capacity should be at or near the rated 2000mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no-charge or error light with the new pack installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries stored in a warehouse can self-discharge to a voltage below what the base station's charge controller recognises as a valid pack — typically under 3.0V. The base sees this as an absent or faulty cell and withholds charging current. Remove the battery, let it sit at room temperature for 30 minutes, then reseat it firmly in the handset and return it to the base. If the error persists, check that the handset contacts are clean and the handset is fully seated — a slight tilt on the cradle breaks the charge circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339982667866,"sku":"BWCS-CPB483CL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339982700634,"sku":"BWCS-CPB483CL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339982733402,"sku":"BWCS-CPB483CL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB483CL-1.webp?v=1778367001","url":"https:\/\/batteryweb.com\/products\/uniden-1711-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
