These handheld diagnostic devices inspect ear canals and tympanic membranes in clinical settings. The battery replaces OEM part numbers 110903 and X-01.99.433 exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNicaTron, NicaTron NC, and NicaTron N compatibility:\u003c\/strong\u003e\n    All three models share the same 2.4V power rail, cell format, and connector pinout. The BMS on each variant expects the same Ni-MH charge profile, so one cell works across the entire platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, load, and self-test on a NicaTron body. The BMS completed its verification sequence without triggering a fault, and voltage held steady under the illumination load through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSelf-test cycle after installation:\u003c\/strong\u003e\n    After fitting this battery, let the device run its full power-on self-test without interruption. The NicaTron's BMS runs a chemistry-verification check at startup — cutting power during this sequence logs a battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm on a freshly charged NicaTron replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NicaTron BMS uses an OEM-calibrated voltage threshold to flag low battery. A new Ni-MH cell has a slightly suppressed open-circuit voltage until it completes its first full charge-discharge cycle. During that initial cycle, the BMS can read the resting voltage as below threshold and trigger the low-battery alarm even when the cell is fully charged. Run one complete charge-discharge cycle before clinical use, and the BMS will map the cell correctly. After that cycle, the alarm clears and does not return unless the battery is genuinely depleted below 2.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNicaTron not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage — typically down to 1.0V per cell or lower over several months. The NicaTron's BMS has a minimum recovery threshold; if the cell arrives below that threshold, the device will not respond at all when the power button is pressed. Place the battery on charge for a minimum of 30 minutes before attempting to power the device on. Once the cell voltage rises above the BMS recovery floor of approximately 2.0V, the device will accept the charge and boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381421736026,"sku":"BWCS-HNM433MD-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381421768794,"sku":"BWCS-HNM433MD-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381421801562,"sku":"BWCS-HNM433MD-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HNM433MD-1.webp?v=1778900661","url":"https:\/\/batteryweb.com\/products\/heine-nicatron-replacement-battery-24v-1400mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
