It fits the RC30-013601 and RC30-0027101 variants. The OEM part number is CP-RC30B.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMamba RC30 series fit:\u003c\/strong\u003e\n    Both the RC30-013601 and RC30-0027101 share the same internal battery bay, connector pinout, and BMS handshake protocol — which is why a single cell covers both revisions. The physical dimensions are 41.30 × 35.00 × 9.20mm, matching the original form factor.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the RC30 platform. The BMS accepted the cell without fault flags, charge termination triggered correctly at full capacity, and the mouse firmware reported battery status accurately throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLi-Polymer swelling check:\u003c\/strong\u003e\n    Before fitting any Li-Polymer cell in a compact mouse shell, press lightly on the pouch surface. A bloated original battery can bow the bottom panel of the Mamba and cause tracking inconsistency — if the shell is no longer flat, replace the cell before continuing use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Mamba drops off USB and won't reconnect after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Razer Mamba stores its USB receiver pairing state in volatile memory tied to the battery circuit. When the cell is fully removed, that pairing context resets. Reinserting a fresh battery doesn't automatically restore the link — the mouse powers on but the receiver hasn't re-established the 2.4GHz session. Unplug the USB receiver, wait ten seconds, replug it, then hold the connect button on the underside of the mouse until the LED flashes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePointer stuttering and micro-lag that appears before the battery indicator drops\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mamba's 2.4GHz polling rate is voltage-sensitive. Once the cell sags below roughly 3.5V under load, the wireless module reduces transmission frequency to conserve power — this shows up as erratic cursor movement before the battery meter visually registers as low. The mouse is still technically on, but the RF link is degrading. Charging to at least 3.7V resting voltage resolves it immediately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377908154458,"sku":"BWCS-RMZ06RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377908187226,"sku":"BWCS-RMZ06RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377908219994,"sku":"BWCS-RMZ06RC-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RMZ06RC-1.webp?v=1778773940","url":"https:\/\/batteryweb.com\/products\/razer-mamba-rc30-013601-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
