It replaces OEM part number 170-2040 in the CR6 handheld unit. Capacity is matched to the original specification at 88.8Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCR6 platform fit:\u003c\/strong\u003e\n    The CR6 uses a fixed 24V Ni-MH pack with a connector and BMS handshake tied to the 170-2040 specification. This replacement meets the same voltage rail and cell count so the device's charge controller recognises it without flagging a fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and full-load discharge on a simulated CR6 load profile. The BMS completed cell balancing without cutoff, and voltage held stable across the discharge curve through the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the CR6 complete its power-on self-test without interrupting the sequence. The device runs a BMS verification at startup — cutting power mid-sequence triggers a false battery fault that does not clear until a full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CR6 BMS rejects a new cell on first boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CR6 charge controller stores the previous cell's discharge signature. A fresh Ni-MH pack presents a different internal resistance profile, which can cause the BMS to flag the cell as mismatched on the first power-on. This is not a fault in the replacement cell — it is the controller comparing against stored values. Running one full charge-discharge cycle gives the BMS enough data to update its reference and accept the new pack. After that cycle, the alarm clears and does not return.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the CR6's charge IC applies a conservative current limit when it does not recognise a seasoned cell profile. The indicator may stop climbing at 85–95% and hold there. This is the IC capping input voltage as a precaution, not a failed charge. Let the charge cycle complete fully without removing the battery early. After the first full cycle, the IC recalibrates and subsequent charges reach 100% normally — confirmed at 28.8V open-circuit at full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381445165146,"sku":"BWCS-BCR600MD-1","price":143.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381445197914,"sku":"BWCS-BCR600MD-2","price":169.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381445230682,"sku":"BWCS-BCR600MD-3","price":189.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCR600MD-1.webp?v=1778900837","url":"https:\/\/batteryweb.com\/products\/biosealer-cr6-replacement-battery-24v-3700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
