It fits cordless DECT handsets that use a three-cell AA-format pack. Install it when the original battery no longer holds charge through a normal call or standby period.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAA x 3 cordless phone compatibility:\u003c\/strong\u003e\n    Many DECT handsets from multiple brands share the same AA x 3 cell arrangement, 3.6V nominal voltage, and two-contact connector. If your original pack matches this physical format and voltage, this replacement slots in without modification to the handset or base cradle.\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 DECT handset platform. The BMS accepted a full charge without triggering a fault state, and terminal voltage held within the expected window across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base cradle and leave it for a full 16 hours before first use. Ni-MH cells shipped in partial-discharge state need a slow, uninterrupted charge to condition the pack and reach rated capacity. Skipping this step shortens effective talk time across all subsequent cycles.\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 Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome DECT base stations check terminal voltage before initiating a charge cycle. A new Ni-MH pack stored for several months can drop below the base's acceptance threshold — typically around 3.0V for a 3.6V nominal pack. The base reads this as a fault rather than an empty battery and refuses to charge. To recover, confirm the handset contacts are clean and seated correctly, then leave it in the cradle undisturbed. Most base stations will trickle-charge a low pack up to the acceptance threshold within 30–60 minutes before switching to normal charge mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReduced range after a battery replacement is usually a voltage-sag issue, not a pairing or antenna fault. When the Ni-MH pack hasn't been fully conditioned, internal resistance is higher than rated, and voltage sags under the RF transmit load. The handset reduces transmit power to compensate, which cuts effective range. Run three to five full charge-discharge cycles through normal use and the internal resistance will drop, allowing the pack to sustain voltage under RF load at rated levels.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339899175002,"sku":"BWCS-CPB044UL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339899207770,"sku":"BWCS-CPB044UL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339899240538,"sku":"BWCS-CPB044UL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB044UL-1.webp?v=1778366907","url":"https:\/\/batteryweb.com\/products\/universel-aa-x-3-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
