It fits the handset directly, restoring normal operation when the original battery no longer holds a charge. Dimensions are 60.00 × 38.12 × 5.75mm — confirm these match your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpeedphone 701 handset fit:\u003c\/strong\u003e\n    The Speedphone 701 uses a slim single-cell Li-ion pack at 3.7V nominal. This cell matches that voltage rail and physical footprint, so the handset's power management circuit recognises it without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench and monitored the protection circuit. The BMS triggered correctly at low-voltage cutoff and did not flag an error during the charge phase.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base station immediately after fitting this battery and leave it for a full uninterrupted charge cycle before making any calls. Li-ion cells shipped in partial-charge storage state benefit from one complete charge before the handset's fuel gauge calibrates correctly.\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 fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell shipped from storage often arrives at around 40–60% state of charge. The handset's internal fuel gauge reads from this partial baseline, so its talk time estimate starts low and stays inaccurate until the gauge resets. Run two full charge-to-cutoff cycles — charge in base until the charge light goes solid, then use the handset until it signals low battery. After two cycles, the gauge recalibrates to the full 1300mAh capacity and talk time estimates stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the old battery cuts all power to the handset, which can clear the DECT registration stored in volatile memory on some Speedphone models. The handset then boots as unregistered and cannot connect to the base. To re-pair, press and hold the registration button on the base station until the base enters pairing mode, then initiate registration from the handset menu. The process takes under two minutes and does not affect phonebook entries stored on the base.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339909136474,"sku":"BWCS-SX930CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339909169242,"sku":"BWCS-SX930CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339909202010,"sku":"BWCS-SX930CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SX930CL-1.webp?v=1778366945","url":"https:\/\/batteryweb.com\/products\/telekom-speedphone-701-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
