It replaces OEM part DA2WB18D2 and uses the same flat-cell format as the original. Capacity is 1500mAh — match that against your current cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH110 \/ H120 \/ H140 \/ H320 compatibility:\u003c\/strong\u003e\n    These four models share the same internal battery bay dimensions and connector pinout. The BMS on each unit expects the same 3.7V nominal cell and cutoff thresholds, so one cell covers the full group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on an H120 unit. The BMS accepted the cell without error, charge termination triggered correctly at full capacity, and low-voltage cutoff fired before the cell dropped below safe discharge limits.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after a cell swap:\u003c\/strong\u003e\n    Media players in this series can enter deep discharge protection after sitting with a depleted cell. Connect the charger immediately after fitting the new battery and allow at least 30 minutes of trickle charge before attempting to power the unit on — skipping this step is the most common reason the device appears dead after installation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after cell swap on the H-series\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe H-series displays battery level by reading cell voltage against fixed thresholds stored in the firmware. After a cell swap, the new cell's voltage curve doesn't match the state the firmware last recorded. For the first several charge and discharge cycles, the indicator will jump — showing 80% then dropping to 40% within minutes. This is a recalibration issue, not a fault. Run three full charge-to-discharge cycles and the readout will stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt the tail end of a discharge, cell voltage sags under the load of the audio amplifier circuit. The H-series amplifier draws enough current that voltage drops below the BMS cutoff threshold before the indicator reaches zero. This is more noticeable with aged cells but can appear with a new cell if the device has been stored in a partially discharged state. A full charge cycle before heavy playback use resolves it — target a full green indicator before starting a long session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381348925530,"sku":"BWCS-H110SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381348958298,"sku":"BWCS-H110SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381348991066,"sku":"BWCS-H110SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-H110SL-1.webp?v=1778900059","url":"https:\/\/batteryweb.com\/products\/iriver-h110-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
