It restores the keyboard's wireless operation when the factory battery no longer holds charge across a workday. Dimensions are 113.10 × 40.70 × 5.80mm — confirm clearance inside the Mojo60 chassis before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMojo60 wireless platform:\u003c\/strong\u003e\n    The Mojo60 runs its Bluetooth stack and RGB backlight from a single Li-Polymer cell. Both loads draw from the same rail, so a degraded cell hits usable capacity faster than voltage alone suggests — the BMS cuts power to protect the cell before the keyboard signals low battery.\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 bench, confirmed BMS handshake, and verified the protection circuit trips correctly at low-voltage cutoff — no runaway draw during RGB-heavy use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRGB and Bluetooth draw management:\u003c\/strong\u003e\n    On the Mojo60, running full RGB brightness alongside active Bluetooth polling pulls the cell voltage down faster than keyboard-only mode. Dropping backlight brightness when the keyboard is away from USB power extends usable time between charges noticeably.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePairing lost after battery swap on the Mojo60\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the Mojo60 loses power completely during a battery swap, the Bluetooth pairing profile stored in RAM is wiped. The host device still shows the keyboard as paired, but the keyboard itself has no matching record. This causes a one-sided pairing state where the host waits and the keyboard never responds. Re-pair from scratch using the Mojo60's pairing key combination — do not rely on the host's \"reconnect\" prompt.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKeyboard connects but input lags or drops characters at low charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs the Li-Polymer cell drops below roughly 3.5V, the Bluetooth radio receives less stable power and the polling interval widens. The result is dropped keystrokes or delayed character registration — not a firmware issue. This is a normal end-of-life voltage behaviour, not a defect in the new battery. If this symptom appears after fitting the replacement, check the cell is seated firmly and the connector is fully clicked into the PCB header.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377906155610,"sku":"BWCS-MGK600SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377906188378,"sku":"BWCS-MGK600SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377906221146,"sku":"BWCS-MGK600SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MGK600SL-1.webp?v=1778773940","url":"https:\/\/batteryweb.com\/products\/melgeek-mojo60-replacement-battery-38v-4100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
