It fits models 23-193, 43-1086, 43-1087, 43-1088, and over 150 additional compatible handsets. When the original pack can no longer hold a charge, this replacement restores wireless operation away from the base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model compatibility across Radio Shack cordless handsets:\u003c\/strong\u003e\n    These handsets share the same 3.6V cell configuration, physical form factor, and connector pinout. One pack covers all models in this family 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 compatible handset base. The BMS accepted charge without fault codes, and voltage held stable across both standby and active RF transmission states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base station and leave it for a full 16 hours before first use. Ni-MH cells shipped in partial-discharge state will not reach rated capacity without this initial slow charge — skipping it leaves usable capacity permanently below spec.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after a battery swap in Radio Shack cordless handsets\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH voltage sags under the RF load that DECT transmitters place on the pack. If the replacement battery has not been fully conditioned through several charge cycles, its internal resistance is higher than a seasoned cell. That elevated resistance causes voltage to dip the moment the handset fires its transmit burst, which the radio interprets as low power and reduces output range. After three to five full charge-discharge cycles, internal resistance drops and transmit voltage stabilises — range returns to normal without any setting changes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light on a freshly installed Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCordless phone base stations use a delta-V detection circuit to confirm a battery is accepting charge. A new Ni-MH pack stored for several months can arrive with a terminal voltage low enough that the base treats it as a fault condition rather than a valid charge target. Remove the handset, wait 30 seconds, then reseat it firmly — this resets the base detection circuit. If the charge light still does not appear, measure the pack voltage directly; anything below 3.0V requires a pre-charge boost from a standalone Ni-MH charger before the base station will accept it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340082544730,"sku":"BWCS-P501CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340082577498,"sku":"BWCS-P501CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340082610266,"sku":"BWCS-P501CL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P501CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/radio-shack-23-193-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
