It fits the original HYLB-867 pack slot and restores field operation when the factory pack has degraded or failed. Voltage and connector match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAE3000H platform fit:\u003c\/strong\u003e\n    The AE3000H runs its sensor array and measurement modules from a single 14.4V rail. This pack matches that rail voltage, the OEM connector pinout, and the BMS communication protocol the instrument expects at startup — so the power management system accepts it without a compatibility fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the AE3000H power-on sequence and monitored BMS handshake, probe initialisation current, and sustained sensor load. The BMS held the output rail stable through the probe power-up spike and maintained voltage under continuous logging load without triggering a protective cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-deployment calibration cycle:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the AE3000H instrument menu before going to the field. The instrument maps battery state during that cycle — skip it and the low-battery warning will trigger too early on your first measurement session, even with a fully charged pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff when the AE3000H probe module initialises\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the AE3000H powers up a probe or sensor module, the instrument draws a sharp inrush current as the module's internal circuits charge. A degraded or deeply discharged pack cannot sustain voltage through that spike, so the BMS reads an undervoltage condition and cuts output before the instrument even reaches the measurement screen. This pack's cells maintain a higher resting voltage under load, which keeps the output rail above the BMS cutoff threshold during probe initialisation. If the instrument still shuts off at that point, check that the pack voltage reads at least 13.0V before powering on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAE3000H readings drifting or resetting mid-logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor operation pulls a steady current from the battery, and if cell internal resistance has risen through age or deep discharge, voltage sags enough mid-session to cause the instrument's processor to momentarily brown out — resetting the active logging buffer without a full shutdown. The symptom looks like data dropout or a measurement reset rather than a power failure, so the battery is often not suspected. Replacing the pack eliminates the voltage sag source; internal resistance on a fresh cell stays low enough to hold the 14.4V rail stable under continuous sensor load. After fitting the replacement, confirm resting pack voltage is at or above 15.2V before a long logging session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43303969390682,"sku":"BWCS-APT300SL-1","price":104.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43303969423450,"sku":"BWCS-APT300SL-2","price":123.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43303969456218,"sku":"BWCS-APT300SL-3","price":137.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-APT300SL_1.webp?v=1777520716","url":"https:\/\/batteryweb.com\/products\/aetep-ae3000h-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
