It replaces the original cell pack when the handset no longer holds charge or talk time has dropped noticeably. Voltage and connector match the SPP-88960 handset bay directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPP-88960 handset compatibility:\u003c\/strong\u003e\n    The SPP-88960 uses a 3.6V Ni-MH cell pack — three NiMH cells in series — with a footprint of 54.46 × 32.07 × 11.22mm. This replacement matches that voltage rail and physical format, so the handset BMS accepts the pack without flagging a fault.\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 Ni-MH compatible tester. The BMS in the SPP-88960 base station accepted the pack from the first charge and showed a normal green charge indicator after a full conditioning cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    Place the handset in the base immediately after installing this battery and leave it for a full 16 hours before using it. NiMH cells in cordless phones need this slow initial charge to reach rated capacity — skipping it results in shortened talk time that does not improve on its own.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping on the SPP-88960 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SPP-88960 DECT radio draws a brief current spike each time the handset transmits. A Ni-MH pack that has not been conditioned yet cannot sustain voltage under that RF load, so the handset drops output power and range shrinks noticeably. This is not a fault with the battery or the phone. Run three to five full charge and discharge cycles through normal use and the pack's internal resistance drops to spec, which keeps voltage stable under transmit load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charging error light after installing a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries that have sat in storage can arrive with a resting voltage below the threshold the SPP-88960 base uses to confirm a valid pack is seated. When the base sees voltage below roughly 3.0V, it may flash an error LED or refuse to start a charge cycle. Remove the handset, wait ten seconds, and reseat it firmly — this resets the base detection circuit. If the error persists, hold the handset in the base for 30 minutes before removing; trickle current from some base stations is enough to bring the pack voltage above the acceptance threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340076941402,"sku":"BWCS-P401CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340076974170,"sku":"BWCS-P401CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340077006938,"sku":"BWCS-P401CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P401CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/sager-spp-88960-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
