It matches the original cell voltage and chemistry so the device's charge management circuit behaves as expected. Capacity is 1800mAh (21.6Wh), sourced from product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCVJ-360 and CVK platform compatibility:\u003c\/strong\u003e\n    These models share the same 12V power rail, connector footprint, and BMS handshake protocol. A single cell specification covers the full platform without modifications to the device or charging cradle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the CVK platform. The BMS accepted the new cell without flagging a chemistry mismatch, and the charge IC ran to completion without truncating early.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full startup self-test without interruption. Medical devices in this class run a BMS verification sequence at boot — cutting power mid-sequence registers a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on a new Ni-MH cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CVJ-360 and CVK units run a multi-step power-on self-test that includes a brief battery load check. A new Ni-MH cell that has partially self-discharged during storage can read low enough during this load pulse to trigger a boot failure before the main OS loads. The BMS threshold for this check is calibrated to a fully charged cell — not a cell at resting storage voltage. Charge the battery to full before the first installation, then power the device on and leave it undisturbed through the complete self-test cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm firing immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis alarm triggers when the BMS samples cell voltage under load and the reading falls below the device's low-battery threshold. On a new Ni-MH cell, internal resistance is slightly elevated for the first several cycles, causing a voltage sag under load that the BMS interprets as a depleted cell even when the cell is fully charged. This is not a fault with the battery — it resolves after 3 to 5 full charge-discharge cycles as the cell's internal resistance normalises. Do not clear the alarm and proceed to clinical use; complete at least one full cycle first and confirm the alarm does not recur under normal operating load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381467676762,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381467709530,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381467742298,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/magnavox-cvj-360-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
