The Air pump is a medical-grade pressure relief device used in clinical and care settings for patient repositioning and alternating pressure management. Voltage and cell count match the original pack so the BMS handshake completes without fault codes.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAir pump platform fit:\u003c\/strong\u003e\n    The 513400-01 battery format is specific to this pump's internal bay — the 4S Li-ion configuration delivers the 14.8V nominal rail the inflation controller expects. Deviating from this voltage spec causes the motor driver to reject the pack and log a supply fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the battery through a full charge-discharge cycle on the Air pump platform, verified BMS communication over the device's data line, and confirmed the charge indicator advanced correctly through each stage without a premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the Air pump to complete its full power-on self-test cycle without interrupting it. The BMS runs a chemistry verification routine at startup — cutting power mid-sequence causes 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\"\u003eWhy the Air pump's charge indicator stalls below 100% on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMedical-grade charge ICs apply a conservative current taper when they see a new cell for the first time. The charge controller reads the cell's internal resistance as higher than a conditioned pack and caps the termination voltage slightly early. This is not a faulty battery — it is the charge IC protecting against overvoltage on an unknown cell. After one full charge-discharge cycle, the controller recalibrates and the indicator reaches full charge consistently.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAir pump fails to power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during warehouse storage, and the 513400-01 pack can drop below the BMS's minimum recovery threshold if it has been stored for several months. When cell voltage falls below approximately 2.5V per cell, the BMS enters a protection lockout and the device will not respond to the power button. Connect the pump to mains power and leave it on charge for at least 90 minutes before attempting to power on — this allows the charger to trickle the cells back above the recovery threshold before the BMS releases the lockout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381438120026,"sku":"BWCS-ARH400MX-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381438152794,"sku":"BWCS-ARH400MX-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381438185562,"sku":"BWCS-ARH400MX-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARH400MX-1.webp?v=1778900837","url":"https:\/\/batteryweb.com\/products\/arjo-huntleigh-air-pump-replacement-battery-148v-6700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
