It fits the same battery bay with the same connector orientation. Voltage and capacity match the OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEP-802, EP-802H, and Freestyl2 compatibility:\u003c\/strong\u003e\n    All three handsets share the same 3.7V single-cell Li-ion bay, connector pin-out, and BMS communication protocol — one battery covers the full range without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the EP-802 base station charge circuit. The BMS accepted the charge handshake immediately, held charge termination voltage at 4.2V, and showed no false low-battery flags during discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the EP-802 base:\u003c\/strong\u003e\n    Li-ion cells shipped in storage state may read as low as 3.0V. Seat the handset in the base immediately after installation and leave it for a full uninterrupted charge cycle before use — the EP-802 base will indicate charge complete when the cell reaches termination voltage.\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\"\u003eA new Li-ion cell delivered from storage has not yet been through a proper full charge-discharge cycle. The EP-802's fuel gauge reads capacity estimates from voltage curves, and a cell that hasn't been fully cycled will report depletion earlier than it should. Run two or three full charge and use cycles through the base station before judging talk time. By the third cycle, measured discharge capacity should be at or near the rated 1200mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEP-802 base station not charging after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the base shows no charge indicator after you seat the handset, the cell voltage may have dropped below the base's acceptance threshold during storage. Remove the handset, wait 10 seconds, and re-seat it firmly — this re-triggers the charge initiation handshake. If the charge light still does not activate, check that the handset contacts are clean and making full contact with the base cradle pins. The base should begin charging once the battery reads above approximately 2.5V, which this cell will at the point of delivery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339915559002,"sku":"BWCS-AY4020CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339915591770,"sku":"BWCS-AY4020CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339915624538,"sku":"BWCS-AY4020CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AY4020CL_1.webp?v=1778366906","url":"https:\/\/batteryweb.com\/products\/engenius-ep-802-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
