It replaces the original rechargeable cell when the handset no longer holds a charge between calls. Dimensions are 31.40 x 30.17 x 10.81mm — verify against the existing battery before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-T991DL handset fit:\u003c\/strong\u003e\n    The KX-T991DL uses a low-capacity 3.6V Ni-MH pack typical of single-cell DECT handsets. The voltage rail and connector position match this replacement directly. No modification needed.\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 Ni-MH compatible charger. The cell accepted charge normally and the voltage held stable under light RF load conditions consistent with DECT handset operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on KX-T991DL:\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 ship partially discharged. A slow first charge lets the cell reach rated capacity — skipping this step cuts usable charge short from day one.\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 no charge or error light after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries lose voltage during storage. If the cell sits in a warehouse for months, it can drop low enough that the base station's charge controller won't recognise it as a valid pack. The base expects to see a voltage above its acceptance threshold before it begins the charge cycle. Place the handset in the base and wait 30 minutes — most KX-series bases will attempt a trickle charge that brings the cell up past the threshold and triggers normal charging.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange reduced on the KX-T991DL after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets draw a short burst of current each time they transmit. With a freshly installed Ni-MH cell that hasn't been fully conditioned, voltage sags under that RF transmit load. The handset's RF output drops when supply voltage dips, which cuts effective range. This is not a fault with the battery or handset. Run three to five full charge-and-discharge cycles and range will normalise as the cell reaches its rated 300mAh capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339988729946,"sku":"BWCS-BTE300CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339988762714,"sku":"BWCS-BTE300CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339988795482,"sku":"BWCS-BTE300CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTE300CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/panafone-kx-t991dl-replacement-battery-36v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
