It restores full handset operation when the original pack can no longer hold a charge. Physical dimensions are 50.03 x 25.78 x 17.99mm — confirm these against your existing battery before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTB236 handset compatibility:\u003c\/strong\u003e\n    Cordless phone handsets sharing the STB236 designation use the same cell format, voltage rail, and connector geometry. If your current battery reads STB236, this pack slots in directly 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 charge and discharge on STB236-compatible handsets. The battery accepts a full charge from the base station without triggering charge faults, and the BMS holds voltage steady through normal standby and talk load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base for a full 16-hour charge before first use. Ni-MH cells shipped in a partially discharged state need a slow initial charge to reach rated capacity — skipping this step is the main reason a new pack feels weaker than expected.\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 Ni-MH cells ship at a fraction of their rated capacity. Full capacity only comes after three to five complete charge-discharge cycles through normal use. If talk time feels short in the first week, that is expected behaviour — not a faulty battery. By cycle five, the pack should settle at its rated 250mAh output.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries can drop below 3.0V during extended storage, which puts them below the threshold some base stations use to detect a valid battery and begin charging. If the charge indicator stays off after seating the handset, remove and reseat the battery once to reset contact, then leave the handset undisturbed in the base for at least 30 minutes. Most base stations will detect the rising voltage and resume normal charging from there. If the light still does not activate, verify the base station contacts are clean and making firm contact with the handset terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339931025498,"sku":"BWCS-CPB479CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339931058266,"sku":"BWCS-CPB479CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339931091034,"sku":"BWCS-CPB479CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB479CL_1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/again-and-again-stb236-replacement-battery-36v-250mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
