It fits the 302 handheld cardiac diagnostic unit used in clinical and patient-side settings. Voltage and capacity match the OEM specification: 12V, 2000mAh (24Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKenz Cardico 302 compatibility:\u003c\/strong\u003e\n    The 302 platform draws on a fixed 12V rail with a proprietary BMS handshake that validates cell chemistry at startup. Ni-MH chemistry is required — the device will reject Li-ion substitutes at the self-test stage due to discharge curve mismatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the 302's power-on sequence and monitored BMS communication across charge and discharge cycles. The protection circuit engaged correctly at low-voltage cutoff and accepted the charger handshake without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the 302 complete its full startup self-test without interruption. The device runs a BMS verification routine at boot — cutting power mid-sequence can latch a false battery fault that won't clear until the next full restart cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKenz Cardico 302 alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 302's BMS compares the incoming cell's discharge profile against a stored threshold calibrated to a conditioned OEM cell. A fresh Ni-MH cell hasn't established that profile yet, so the monitor can flag low battery even when the pack is fully charged. This is a first-cycle calibration issue, not a fault with the battery. Run one complete charge-to-discharge cycle before clinical use — after that cycle, the BMS updates its reference and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice fails to power on after the replacement cell sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day in storage. A cell that has sat for several months can drop below the 302's BMS recovery threshold — typically around 9V for a 12V Ni-MH pack — at which point the monitor won't boot at all. Connect the battery to the device charger and leave it for a full uninterrupted charge cycle before attempting to power on. If the charger LED doesn't respond within 30 minutes, measure pack voltage directly — anything below 8V requires a slow pre-charge trickle to recover the cells.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381510963290,"sku":"BWCS-KZC302MD-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381510996058,"sku":"BWCS-KZC302MD-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381511028826,"sku":"BWCS-KZC302MD-3","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KZC302MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/kenz-cardico-302-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
