It fits directly into the handset battery compartment and restores power to a phone that no longer holds a charge. Voltage and cell chemistry match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBanani D300 handset fit:\u003c\/strong\u003e\n    The D300 base station charges at a fixed low-current rate matched to 3.6V Ni-MH cells. Swapping to a different voltage or chemistry would cause the base to under- or overcharge the pack, so cell matching here is not optional.\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 Ni-MH test fixture. The BMS accepted charge at the base station charge rate, voltage held steady across three full cycles, and the pack reached rated capacity by cycle four.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing this battery, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells that have been in storage ship partially discharged and need a slow, uninterrupted first charge to reach their rated 700mAh capacity.\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 flashing error light after fitting a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries drop to around 3.0V or lower during long storage. Some DECT base stations run a voltage check before starting the charge cycle and refuse to charge a pack that reads below their acceptance threshold. The base station is not faulty — it is waiting for a minimum voltage it is not seeing. To recover the pack, briefly connect it to a standalone Ni-MH charger at a low rate (around 50mA) until the pack reads at least 3.3V, then return it to the base. The base should then accept it and begin the normal charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not re-pairing with the base after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a DECT handset cuts all power to the registration memory on some models, and the handset loses its pairing with the base. The phone and base are both fine — the link just needs to be re-established. Hold the paging or find button on the base for five seconds, then follow the handset's register or pair menu. On most DECT phones this takes under two minutes and does not require a PIN beyond the default 0000.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340062457946,"sku":"BWCS-ALM100CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340062490714,"sku":"BWCS-ALM100CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340062523482,"sku":"BWCS-ALM100CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALM100CL-1.webp?v=1778367023","url":"https:\/\/batteryweb.com\/products\/bruno-banani-d300-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
