It fits cordless DECT phone handsets that use this AAA-format triple-cell pack. Check your handset battery compartment or original pack for either part number before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAAA triple-cell NiMH pack format:\u003c\/strong\u003e\n    Cordless phones using H-AAA550BX3 and H-AAA600BX3 share the same three-cell AAA NiMH configuration, voltage rail, and connector orientation. Both part numbers cross to this 700mAh pack.\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 cordless handset base station. The BMS accepted charge without error from cycle one, and voltage held steady through normal standby and active call loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base for a full 16-hour slow charge before first use. NiMH cordless phone batteries do not reach rated capacity on a fast first charge — skipping this step will result in noticeably shorter talk time until the pack is properly conditioned.\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 on a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells self-discharge during storage. By the time a replacement pack reaches the handset, cell voltage can drop low enough that the base station's charge controller rejects it. Most DECT bases require a minimum pack voltage before the charging circuit activates. If the charge LED does not come on, remove the handset, wait 30 seconds, and reseat it firmly. If the base still shows no charge, confirm resting pack voltage is above 3.0V before returning the unit.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drops noticeably when the NiMH pack voltage sags under RF load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets transmit in short radio bursts. Each burst draws a spike of current that causes NiMH voltage to sag momentarily. When the pack is low or not yet conditioned, that voltage sag crosses the handset's transmit threshold and the RF output power drops — which the user experiences as reduced range or choppy audio. This is not a pairing issue or a base station fault. Run three to five full charge and discharge cycles to condition the pack, and confirm resting voltage reads at or above 3.6V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339871617114,"sku":"BWCS-MTD716CL-1","price":205.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339871649882,"sku":"BWCS-MTD716CL-2","price":245.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339871682650,"sku":"BWCS-MTD716CL-3","price":275.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTD716CL-1.webp?v=1778366872","url":"https:\/\/batteryweb.com\/products\/byd-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
