It matches the OEM part numbers 120031 and BATT\/110031. Swap it in when the original cell no longer holds charge or fails the device's power-on self-test.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEK606 platform fit:\u003c\/strong\u003e\n    The EK606 uses a fixed 21.6V rail with a BMS that handshakes on connector polarity and thermistor signal. This cell matches that connector pinout and includes the NTC thermistor line the charge IC expects — without it, the device flags a battery fault and refuses to charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the EK606's charge-discharge profile and confirmed the BMS accepted the thermistor handshake on first connection. Capacity tracked within 4% of rated 3000mAh after the second full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test requirement:\u003c\/strong\u003e\n    After installation, allow the EK606 to complete its full power-on self-test without interruption. Cutting power during BMS verification locks in a false battery fault that persists until the next clean cold boot — it will alarm low battery even on a full cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEK606 charge indicator stalling below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn a new Ni-MH cell, the EK606's charge IC applies a conservative current ceiling during the first charge cycle. It reads the cell's internal resistance as higher than a conditioned pack and backs off before reaching full termination voltage. This is not a fault — it is the charge controller protecting an uncharacterised cell. Run one complete charge-discharge cycle and the IC recalibrates; subsequent charges reach full capacity and terminate correctly at 21.6V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEK606 will not power on after replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day in storage. If this battery sat unshipped or unused for several weeks, its resting voltage may have dropped below the EK606's BMS recovery threshold — typically around 18V on a 21.6V pack. The BMS interprets this as a deeply discharged or faulty cell and blocks power-on to protect the circuit. Connect the device to mains power and leave it on charge for a minimum of 30 minutes before attempting to boot; most charge ICs include a trickle pre-charge stage that recovers cells above the hard-cutoff floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381494972506,"sku":"BWCS-DEK606MD-1","price":127.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381495005274,"sku":"BWCS-DEK606MD-2","price":150.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381495038042,"sku":"BWCS-DEK606MD-3","price":168.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEK606MD-1.webp?v=1778901249","url":"https:\/\/batteryweb.com\/products\/dimeq-ek606-replacement-battery-216v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
