It fits the 23-193 along with models 43-1086, 43-1087, 43-1088, and over 150 additional compatible handsets. Physical dimensions are 50.57 x 42.47 x 14.35mm — same footprint as the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-compatible handset lineup:\u003c\/strong\u003e\n    These Radio Shack models share the same battery bay dimensions, connector orientation, and 3.6V charging rail. The base station charges at a fixed voltage, so all handsets in this family accept the same Ni-MH pack without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on a 23-193 handset. The BMS accepted charge from the base on the first placement and voltage climbed steadily to 4.2V at full charge with no error signalling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before use. Ni-MH cells shipped in storage-discharged state need a slow initial charge to reach rated 1300mAh capacity — skipping this results in shorter talk time on the first several cycles.\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 expected after a new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver full rated capacity on cycle one. The electrochemical structure needs three to five full charge-discharge cycles before capacity stabilises at the rated 1300mAh. If talk time feels short immediately after install, that is normal — not a defective cell. Run the handset until it signals low battery, return it to the base for a full charge, and repeat three to five times.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eBatteries stored in a warehouse can self-discharge to below 3.0V. Some base stations will not initiate a charge cycle if the pack voltage is too low at first contact. Remove the handset, wait 10 seconds, and reseat it firmly — this resets the charge detection circuit on most Radio Shack base models. If the error persists, a brief trickle charge from a standalone Ni-MH charger at 50–100mA will bring the cell above the 3.2V acceptance threshold the base requires.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340073238618,"sku":"BWCS-P501HL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340073271386,"sku":"BWCS-P501HL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340073304154,"sku":"BWCS-P501HL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P501HL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/radio-shack-23-193-replacement-battery-36v-1300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
