It fits the 863300, 863301, and 863302 variants, as well as the broader Efficia CM120 platform. The cell format, connector pinout, and BMS handshake match the RRC2020 and RRC2020-L OEM specifications.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEffica and Efficia CM-series compatibility:\u003c\/strong\u003e\n    The CM100 and CM120 platforms share the same battery bay geometry, voltage rail, and BMS communication protocol. A single RRC2020-format pack covers both series because Philips standardised the battery interface across this defibrillator family when the CM120 launched.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through a full charge-discharge sequence and monitored BMS handshake behaviour at startup. The pack passed the device's internal self-test without triggering a battery fault flag, and charge termination occurred correctly at the expected cell-level voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, do not interrupt the device's power-on self-test sequence. The Effica CM100 runs a BMS verification routine at boot that checks cell chemistry against stored OEM thresholds. Cutting power during this window causes the device to log a persistent battery fault that does not clear until a complete reboot from a full-charge state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Effica CM100 may not complete its boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CM100's BMS stores a learned charge profile from the previous pack. When a new cell is installed, the device compares the incoming voltage signature against that stored baseline. If the new cell arrived at a lower state of charge than the OEM pack it replaced, the BMS can stall mid-boot waiting for a voltage value it does not receive. Charge the replacement pack fully before first installation — target the device's charge-complete indicator, not a timer — then install and allow the full self-test to run without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after installation, the Effica CM100 charge IC applies a conservative current limit to an unrecognised cell until it completes one full charge-discharge cycle. This is normal behaviour and not a fault with the battery or charger. The indicator may plateau below 100% and stay there until the BMS has logged a complete cycle. Run one full charge to completion, discharge the device through normal use or a supervised test cycle, then recharge — the indicator should reach 100% on the second charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381465710682,"sku":"BWCS-PHM500MD-1","price":161.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381465743450,"sku":"BWCS-PHM500MD-2","price":189.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381465776218,"sku":"BWCS-PHM500MD-3","price":209.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHM500MD_1.webp?v=1778901015","url":"https:\/\/batteryweb.com\/products\/philips-effica-cm100-863300-replacement-battery-108v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
