It slots into either model, restoring power to the handset when the original cell can no longer hold a usable charge. Voltage and capacity match the factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDM-150 and DM-160 shared platform:\u003c\/strong\u003e\n    Both models run on the same 3.7V single-cell architecture with an identical battery bay and connector pinout. The BMS handshake is consistent across the two, so one cell fits both 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 the DM-150 platform. The BMS accepted the cell on first connection, charge termination triggered correctly at 4.2V, and the protection circuit tripped cleanly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to near-empty and charge to 100% before enabling any fast-charge option. The phone's fuel gauge IC was calibrated to the old cell's discharge curve — one complete cycle rewrites that baseline against the new cell and stops the percentage reading drifting mid-use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the DM-150 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff failure, not a capacity problem. Under modem radio or screen load, the new cell's voltage drops faster than the fuel gauge IC expects, hitting the hardware cutoff before the displayed percentage reaches zero. The phone reads 25% but the actual cell voltage under load has already fallen below the 3.0V protection threshold. One full discharge-charge cycle after fitting the new battery lets the coulomb counter re-learn the cell's real discharge curve and eliminates the early shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells ship partially charged, but if the battery was stored for an extended period before fitting, the cell voltage may have dropped below 2.5V — the point at which the BMS locks out to prevent cell damage. The phone will show no charge indicator and appear completely dead. Connect the phone to a wall charger rather than a PC USB port, which delivers higher current and is more likely to push enough trickle current through the BMS lockout circuit. Leave it on charge undisturbed for 20–30 minutes; once the cell climbs back above 2.7V the BMS releases and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409444143194,"sku":"BWCS-KG120SL-1","price":22.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409444175962,"sku":"BWCS-KG120SL-2","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409444208730,"sku":"BWCS-KG120SL-3","price":27.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KG120SL-big.webp?v=1779579707","url":"https:\/\/batteryweb.com\/products\/lg-dm-150-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
