It replaces OEM part numbers PT6, PK1278C, and T1B603A. When the original pack stops holding charge, this is the direct swap to restore handset operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC900 series handset fit:\u003c\/strong\u003e\n    The MC900, MC901, and MC902 share the same battery bay dimensions and 3.6V NiMH voltage rail. All three models use the same connector orientation and cell format — 46.60 × 31.40 × 10.60mm — so one pack covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the base station charge circuit and confirmed the BMS accepted charge current without error flags. Voltage held steady at 3.6V nominal across the full discharge curve under a simulated standby and talk load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on NiMH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless phones need a slow initial charge to reach rated capacity — skipping this shortens every subsequent cycle.\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 an error light after fitting a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries lose voltage during storage. If a new pack sits in a warehouse for several months, its resting voltage can drop low enough that the MC900 series base station charge circuit refuses to start. The base interprets a deeply discharged cell as a fault condition rather than a flat battery. To recover it, hold the handset firmly in the cradle for at least 30 minutes — most base stations will begin trickle-charging once the cell voltage climbs back above approximately 3.0V and then switch to normal charge mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells do not deliver full rated capacity on the first charge cycle — this is normal chemistry behaviour, not a defective battery. Capacity builds over three to five full charge-discharge cycles as the cell chemistry stabilises. Run the handset until the low-battery indicator activates, then return it to the base for a full charge. By cycle five, output should reach close to the rated 700mAh.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339999936602,"sku":"BWCS-MC902CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339999969370,"sku":"BWCS-MC902CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340000002138,"sku":"BWCS-MC902CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MC902CL-1.webp?v=1778367046","url":"https:\/\/batteryweb.com\/products\/matracom-mc901-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
