It replaces the original handset battery when the existing pack no longer holds a charge. Physical dimensions are 53.67 x 45.98 x 15.64mm — confirm fit against your existing battery before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAM1930 \/ AM1933 \/ AM1963 \/ VT1910C compatibility:\u003c\/strong\u003e\n    These models share the same handset battery bay dimensions, connector polarity, and 3.6V three-cell NiMH configuration. One part covers all four variants without modification.\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 NiMH test rig. The cell voltage held above 3.4V under a 200mA load typical of DECT handset draw, and the pack reached rated 2000mAh capacity by cycle four.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge for Ameritech NiMH handsets:\u003c\/strong\u003e\n    Place the handset in the base cradle for a full 16-hour charge before first use. NiMH cells in cordless phone packs arrive partially discharged from storage. Skipping this slow initial charge leaves capacity 20–30% short of rated on the first day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charging error on a freshly installed NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAmeritech base stations use a delta-V detection circuit to confirm a NiMH battery is present and accepting charge. A pack that has sat in storage drops below the base's acceptance threshold — typically under 3.0V — and the base reads it as a fault rather than a dischargeable cell. The fix is to seat the handset firmly in the base and leave it for at least one hour without removing it. Most bases re-poll the battery voltage after a short rest, detect the rising cell voltage, and resume normal charging.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drops noticeably mid-call after replacing the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets draw a spike of current each time the RF module transmits a burst — typically every 10ms in DECT's TDMA frame. A NiMH pack that hasn't completed its first few conditioning cycles has higher internal resistance, causing voltage to sag during each transmit spike. The handset's RF circuit reduces output power when supply voltage sags, which cuts effective range. Running three to five full charge-discharge cycles brings internal resistance down and stabilises the voltage under RF load — range returns to normal without any hardware change.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339985387610,"sku":"BWCS-BPT23CL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339985420378,"sku":"BWCS-BPT23CL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339985453146,"sku":"BWCS-BPT23CL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPT23CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/ameritech-am1930-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
