It matches OEM part number T426 and fits directly into the handset battery compartment. Voltage and cell count are identical to the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMira Plus and Voice compatibility:\u003c\/strong\u003e\n    Both handsets share the same battery bay dimensions, 3.6V three-cell Ni-MH configuration, and base station charging contacts. One pack covers both models 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 the Mira Plus base station and confirmed the charging circuit accepted the NiMH voltage curve without fault. The BMS on these handsets monitors charge termination via delta-V — the cell chemistry here triggers that cutoff cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge discipline on NiMH cordless packs:\u003c\/strong\u003e\n    Place the handset in the base immediately after installation and leave it for a full 16 hours before first use. NiMH cells in cordless phones need that slow initial charge to reach rated capacity — skipping it leaves you with noticeably shorter talk sessions for the first several uses.\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\"\u003eNew NiMH cells ship in a partially discharged state and need three to five full charge-discharge cycles before they reach rated capacity. The Mira Plus base charges at a trickle rate, so partial cycles — picking up the handset before it fully charges — slow the conditioning process. Run the handset until it gives a low-battery alert, then return it to the base for a complete charge. After five full cycles, capacity should stabilise at or near the rated 1200mAh.\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\"\u003eNiMH packs can drop below the voltage threshold the Mira Plus base expects after sitting in storage. If the base does not show a charge indicator within a few minutes of seating the handset, remove and reseat the handset firmly — poor contact on the charging pins is the most common cause. If the light still does not activate, the pack voltage may be too low for the base to recognise; place the handset in the base for 30 minutes undisturbed, then check again. Most bases will begin charging once the pack recovers to approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340046106714,"sku":"BWCS-DET426CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340046139482,"sku":"BWCS-DET426CL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340046172250,"sku":"BWCS-DET426CL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DET426CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/olympia-mira-plus-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
