It replaces the original factory pack when talk time has dropped or the handset no longer holds a charge. Dimensions are 40.00 × 42.00 × 13.50mm — sized to fit the original battery compartment.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTEC2000 and TEC3000 shared platform:\u003c\/strong\u003e\n    Both models run the same 3.6V three-cell Ni-MH pack with matching connector orientation and physical footprint. One battery covers both handsets without any 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 a Ni-MH compatible charger, confirmed the cell voltage rose steadily to 4.2V at full charge, and verified the protection circuit did not trip under normal cordless phone standby and talk loads.\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 station and leave it for a full 16 hours before first use. Ni-MH cells arrive partially discharged from storage and need a slow, uninterrupted initial charge to reach rated 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 a charging error with the new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCordless phone base stations detect a charging battery by watching for a voltage rise above a minimum threshold — typically around 3.0V for a 3.6V Ni-MH pack. A replacement battery that has been sitting in a warehouse can self-discharge below that threshold. When the base sees voltage too low, it reads the pack as faulty rather than empty. Placing the handset in the base for 30 minutes usually allows the cells to recover enough voltage for the charger to accept them. If the error light persists past that point, check that the handset contacts are clean and fully seated against the base cradle terminals.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver full rated capacity on the first cycle out of storage — 600mAh is the figure reached after three to five full charge-discharge cycles. On cycle one, you may see noticeably shorter talk time, and it will improve with each subsequent charge. This is a chemistry characteristic, not a defect. Run three complete cycles — full charge in base, use until handset signals low battery, return to base — and talk time will stabilise at the rated level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340110921818,"sku":"BWCS-P302CL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340110954586,"sku":"BWCS-P302CL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340110987354,"sku":"BWCS-P302CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P302CL_1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/emerson-tec2000-replacement-battery-36v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
