It powers the motorised aspiration and dispensing mechanism used in laboratory and clinical liquid handling. Fits the accu-jet pro (Part No 26630).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eaccu-jet pro compatibility:\u003c\/strong\u003e\n    The accu-jet pro runs a 2.4V Ni-MH cell throughout its production history. This replacement matches the original voltage rail and physical dimensions (45.00 × 20.60 × 10.50mm), so the BMS handshake and charge IC operate as expected without modifications.\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 accu-jet pro platform. The BMS accepted the new cell, completed its verification sequence, and the charge indicator advanced normally after the first full charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation power-on sequence:\u003c\/strong\u003e\n    After fitting this cell, allow the accu-jet pro to complete its full power-on self-test without interrupting the cycle. The device runs a BMS verification at startup — cutting power during this window triggers a false battery fault that persists until the next complete 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 accu-jet pro reports low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe accu-jet pro's charge IC applies a conservative acceptance threshold calibrated to an aged OEM cell. A new 700mAh Ni-MH cell has a slightly different internal resistance profile, which the BMS initially reads as below the pass threshold. One complete charge-discharge-recharge cycle allows the BMS to update its reference values. After that cycle, the low-battery alarm clears and the charge indicator reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eaccu-jet pro not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If the cell voltage drops below approximately 2.0V, the accu-jet pro's BMS will not initiate a boot sequence — it sees the pack as unrecoverable and refuses to draw from it. Place the device on charge for a minimum of 30 minutes before attempting to power on. This allows the charge IC to raise the cell above the BMS recovery threshold and re-enable the startup sequence.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381501395034,"sku":"BWCS-BTH630MD-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381501427802,"sku":"BWCS-BTH630MD-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381501460570,"sku":"BWCS-BTH630MD-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTH630MD-1.webp?v=1778901304","url":"https:\/\/batteryweb.com\/products\/brandtech-accu-jet-pro-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
