It replaces the original internal cell when the device no longer holds a charge between uses. Dimensions are 81.08 × 59.78 × 4.22mm — measure your existing cell before fitting if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMA02 and ROG Claymore I compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, voltage rail, and connector pinout, which is why a single cell covers both. The BMS inside the Claymore I expects a 3.85V nominal input — do not substitute a 3.7V cell, as the charge controller will undercharge it and report inaccurate capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Claymore I's onboard BMS and confirmed full charge acceptance, accurate LED fuel-gauge reporting, and clean cutoff at the low-voltage protection threshold. No false low-battery alerts appeared during the test sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration on the Claymore I:\u003c\/strong\u003e\n    After fitting a new cell, run the keyboard down to the low-battery warning via normal use, then charge it uninterrupted to 100%. The Claymore I's fuel gauge recalibrates against this full cycle — skipping it can leave the battery indicator reading 20–30% low for weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ROG Claymore I drains faster with RGB and high polling enabled\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Claymore I draws significantly more current when per-key RGB lighting and 1000Hz wireless polling are both active. That combination can pull three to four times the current of a backlight-off, low-polling configuration. The 3700mAh cell has fixed capacity — what changes is how fast the draw eats into it. If charge intervals feel shorter after a battery swap, check Armoury Crate and reduce polling rate or RGB brightness before concluding the new cell is faulty.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKeyboard pairing lost after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA full power loss during the cell swap clears the Claymore I's active pairing state in some firmware versions. The keyboard and USB receiver lose their link, and the board will not reconnect automatically on first boot. Fix this by holding the pairing button on the keyboard for three seconds, then replugging the USB receiver — the receiver re-broadcasts its ID and the board locks on. If the board still shows no input in Windows, check Device Manager to confirm the receiver is enumerated before attempting a second pair cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377916149850,"sku":"BWCS-AUB555SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377916182618,"sku":"BWCS-AUB555SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377916215386,"sku":"BWCS-AUB555SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUB555SL-1.webp?v=1778773918","url":"https:\/\/batteryweb.com\/products\/asus-ma02-replacement-battery-385v-3700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
