It fits models 18560, 239037, 9600509, and GESPC910. It slots into the handset battery compartment and connects directly to the existing contacts.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhy these models share this pack:\u003c\/strong\u003e\n    The 18560, 239037, 9600509, and GESPC910 handsets all run on the same 3.6V single-cell Ni-MH rail with matching contact spacing and physical dimensions (73.36 × 48.30 × 14.44mm). One pack covers all four without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a DECT handset platform. The BMS accepted the full charge cycle without triggering a fault, and voltage held steady across the transmit load during RF bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a NiMH cordless handset:\u003c\/strong\u003e\n    After installing, seat the handset in the base cradle and leave it for a full 16 hours before first use. NiMH cells in cordless phones need that slow initial charge to reach rated capacity — skipping it locks you into a reduced capacity ceiling for the life of the pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after swapping the battery pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH pack sitting in a warehouse drops voltage during storage. Some Radio Shack base stations check for a minimum voltage at the cradle contacts before they start the charge circuit — if the pack comes in too low, the base reads it as a fault and shows no charge indicator. This is not a defective battery or a faulty base. Seat the handset in the cradle anyway and leave it undisturbed for several hours; most base units will begin trickle charging once the pack climbs past the acceptance threshold, typically around 3.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping mid-call after a battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets ramp transmit power to maintain the link to the base station as distance increases. When a Ni-MH pack is not fully conditioned, voltage sags under that RF load and the handset cannot sustain the power level needed at range. The result is a dropped call or broken audio even though the battery indicator still shows charge. Run three to five full charge and discharge cycles to condition the cells, and check that the handset sits fully and evenly in the base cradle each time — a partial contact charges unevenly and makes the sag worse.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339941904474,"sku":"BWCS-BP901CL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339941937242,"sku":"BWCS-BP901CL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339941970010,"sku":"BWCS-BP901CL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP901CL_1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/radio-shack-18560-replacement-battery-36v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
