It fits the Nokia Lumia 630, 635, 636, and 638 smartphones. The BL-5H connector and cell dimensions match the original bay — 78.50 x 37.75 x 5.20mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLumia 630 \/ 635 \/ 636 \/ 638 compatibility:\u003c\/strong\u003e\n    All four models share the same BL-5H form factor, voltage rail, and connector pin-out. The BMS handshake is identical across the series, so one cell covers the full platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Lumia 635 unit. The BMS accepted charge from first insertion, and the protection circuit tripped correctly at the low-voltage cutoff threshold during discharge stress testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the Lumia's fuel gauge IC a clean reference curve against the new cell before any high-current charging session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Lumia 630 shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lumia 630 uses a coulomb counter that was calibrated to the discharge curve of the original cell. A new cell with a slightly different voltage-versus-capacity curve can cause the OS to misread remaining charge. When the modem fires up for a call or the screen hits full brightness, the actual cell voltage drops below the shutdown threshold before the OS expected it. One full discharge-charge cycle on the new cell resets the fuel gauge IC's reference points and stops premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the BL-5H sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the BL-5H dropped below approximately 2.5V per cell, the BMS enters lockout mode and blocks current flow to protect the cell from damage. The phone will show no response — no charging animation, no boot. Connect to a wall charger rather than a PC port, which supplies a steady 5V at higher current. Leave it for 20–30 minutes without interruption; the BMS needs a sustained trickle above the lockout threshold before it re-enables the charge path. Once the screen shows a charging indicator, the BMS has re-initialised.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404274106458,"sku":"BWCS-NK630SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404274139226,"sku":"BWCS-NK630SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404274171994,"sku":"BWCS-NK630SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK630SL-1.webp?v=1779369616","url":"https:\/\/batteryweb.com\/products\/nokia-lumia-630-replacement-battery-37v-1650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
