It fits the DM221, DM221-2, DM222, and Digital Audio Monitor DM221 handsets.

The BMS accepted a full charge without rejection, and the unit held a stable 2.4V rail throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pair after swap:\u003c\/strong\u003e\n    After replacing the battery, re-pair the parent unit with the camera unit. The DM221 drops its wireless link when the parent unit loses power completely — the link does not restore automatically on power-up.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit range dropping after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DM221's 2.4GHz radio draws more current at distance — the transmitter power scales with available voltage. A new Ni-MH cell that hasn't completed its first full charge cycle sits below its rated terminal voltage, and that directly cuts radio range. This is not a fault with the unit or the battery. Charge the parent unit fully before first use and range returns to normal. A full charge on a 700mAh Ni-MH pack takes approximately 14–16 hours on the DM221's trickle charger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit screen stays on overnight and battery is flat by morning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DM221 parent unit backlit screen is the largest single current draw in normal operation — significantly more than the radio receiver. If the screen timeout is disabled or set too long, sustained overnight screen-on operation will drain a 700mAh Ni-MH cell before morning. Go into the parent unit settings and enable the screen auto-off timer. Set it to the shortest interval that still works for your monitoring routine — the audio alert continues to function regardless of screen state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315067027546,"sku":"BWCS-VDM221MB-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315067060314,"sku":"BWCS-VDM221MB-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315067093082,"sku":"BWCS-VDM221MB-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VDM221MB-1.webp?v=1777949713","url":"https:\/\/batteryweb.com\/products\/v-tech-dm221-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
