It fits the same physical bay and connector as the original pack. Verify your handset's battery compartment label against those part numbers before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-part-number coverage:\u003c\/strong\u003e\n    Radio Shack used at least three separate part numbers for the same 2.4V Ni-MH cell across different handset production runs. The voltage rail, connector pitch, and contact polarity are identical across all three, so one replacement covers the full spread.\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 a 2.4V Ni-MH-compatible charger. The BMS accepted charge normally, held voltage under light RF-simulate load, and showed no false-full cutoff on the first three cycles.\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 and leave it for a full 16 hours before the first call. Ni-MH cells shipped in partial-charge state — a slow initial charge lets each cell in the pack reach equal capacity and prevents one cell dragging the other down prematurely.\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 a charging error light after fitting a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRadio Shack base stations use a delta-V detection circuit to confirm a valid Ni-MH pack is seated. A battery that arrives from storage at very low voltage — sometimes below 2.0V across the pack — sits outside the window the base expects to see at charge start. The base reads that as a fault rather than a depleted pack and throws an error light instead of beginning charge. The fix is straightforward: trickle-charge the pack externally at around 50mA for 20–30 minutes to bring resting voltage above 2.1V, then reseat it in the base. At that voltage the delta-V circuit recognises the pack and normal fast-charge begins.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than original battery after the first few uses\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not ship at rated capacity — they need three to five full charge-discharge cycles before the crystal structure in the electrode settles and the cell reaches its rated 1500mAh. If talk time feels short immediately after install, that is normal and not a fault with the pack. Each subsequent full charge-to-discharge cycle adds measurable capacity until the cell plateaus around cycle four or five. Run the handset until it signals low battery, return it to the base for a full charge, and repeat — do not top-up mid-cycle during the conditioning window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340086083674,"sku":"BWCS-P513CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340086116442,"sku":"BWCS-P513CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340086149210,"sku":"BWCS-P513CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P513CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/radio-shack-replacement-battery-24v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
