It replaces the original pack when the handset no longer holds a charge through a normal day of calls and standby. Physical dimensions are 50 x 42 x 14mm — verify clearance in your handset before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDS-900 \/ JB-900 \/ ME-900 platform fit:\u003c\/strong\u003e\n    These four models share the same handset battery bay dimensions, cell count, and connector orientation. A single 3.6V, three-cell Ni-MH pack covers all of them — no adapter or wiring change needed.\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 the DS-900 platform. The base station accepted the pack without error, and voltage held steady across the RF transmit bursts typical of DECT handsets.\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 and leave it for a full 16 hours before making any calls. Ni-MH cells shipped from storage are partially discharged — a slow first charge is what lets them reach rated 1500mAh capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells need three to five full charge-discharge cycles before they reach rated capacity. A new pack pulled from storage will underperform on the first day — this is chemistry, not a fault. Run the handset until the low-battery tone sounds, then return it to the base for a full charge. Repeat that cycle four times and capacity will stabilise at the rated 1500mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating on a freshly installed pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Aastra base stations use a voltage threshold to confirm a valid battery before starting the charge circuit. A pack that has self-discharged below roughly 3.0V during storage may sit below that threshold. Remove the handset, wait 10 seconds, then re-seat it firmly — the contact pressure resets the detection circuit. If the light still does not activate, check that the handset contacts and base contacts are clean and free of oxidation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339968282714,"sku":"BWCS-CPB400JL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339968315482,"sku":"BWCS-CPB400JL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339968348250,"sku":"BWCS-CPB400JL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB400JL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/aastra-ds-900-replacement-battery-36v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
