It carries OEM part number 10HE200aa and slots into the same battery bay as the original cell. Capacity is 2000mAh (24Wh), matching the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDAIWHA DI-2000 platform fit:\u003c\/strong\u003e\n    The DI-2000 uses a fixed 12V Ni-MH chemistry requirement tied to its BMS handshake and charge IC. Substituting a different chemistry — even at the same voltage — will cause charge faults or self-test failures. This cell matches the chemistry the device expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a DI-2000 unit. The BMS completed its verification pass, the charge IC accepted the cell without fault codes, and the device exited self-test cleanly on the second cycle after an initial calibration pass.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the DI-2000 complete its power-on self-test without interruption. The device runs a BMS verification at startup, and cutting power mid-sequence stores a false battery fault that will persist until the next full reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DI-2000 alarms low battery after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DI-2000's BMS uses a learned capacity threshold calibrated to the previous cell's charge curve. A new Ni-MH cell has a slightly different internal resistance profile during its first few cycles, which can read below the BMS acceptance threshold even when fully charged. This triggers a low battery alarm that is not a cell defect — it is the BMS flagging an unrecognised charge signature. One complete charge-discharge cycle allows the BMS to update its reference baseline and clear the alarm.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day at room temperature. A cell stored for several months can drop below 9V — the DI-2000's BMS recovery threshold — and the device will not attempt to boot. Place the battery on a compatible Ni-MH charger for a full uninterrupted charge cycle before fitting it. If the charger shows no charge acceptance, check cell voltage with a multimeter; below 8V, apply a slow trickle charge at 0.1C to bring the cell above the BMS wake threshold before switching to normal charge rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381369602138,"sku":"BWCS-MDF200MD-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381369634906,"sku":"BWCS-MDF200MD-2","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381369667674,"sku":"BWCS-MDF200MD-3","price":93.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDF200MD-1.webp?v=1778900448","url":"https:\/\/batteryweb.com\/products\/medifosion-daiwha-di-2000-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
