It replaces OEM part BPHPS140 and restores power to the HPS140 when the original pack no longer holds a usable charge. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHPS140 pack fit:\u003c\/strong\u003e\n    The HPS140 runs a 4-cell Ni-MH stack at 4.8V nominal. This replacement uses the same cell count and connector orientation, so the instrument's charge circuit and low-voltage cutoff thresholds behave the same way they did with the factory pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the pack through charge and discharge under a simulated instrument load. The BMS held cutoff voltage correctly and the pack delivered consistent output across repeated cycles without premature shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment after install:\u003c\/strong\u003e\n    Run a full calibration cycle through the HPS140 instrument menu before taking it into the field. The instrument maps battery state during calibration — skip this and you will see premature low-battery warnings on the 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\"\u003eHPS140 shutting down mid-measurement with charge still showing\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells sag under sustained sensor load. The HPS140 draws a sustained current during active measurement, and an aged or partially discharged pack can dip below the instrument's cutoff threshold even when the display still shows charge remaining. A new pack eliminates this voltage sag. After fitting the replacement, fully charge before first use and run the calibration cycle so the instrument recalibrates its low-voltage threshold to the new cells.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack will not charge after the HPS140 sat unused for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge in storage, and if the pack drops below approximately 1.0V per cell — around 4.0V total — the charger circuit in the HPS140 may refuse to initiate a charge cycle. This is a voltage-floor protection response, not a charger fault. Connect the instrument to the charger and leave it for at least 30 minutes without interruption; some chargers apply a trickle pre-charge to recover cells from this state. If the pack does not respond after 45 minutes on charge, the original cells are unrecoverable and the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360605044826,"sku":"BWCS-VPS140SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360605077594,"sku":"BWCS-VPS140SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360605110362,"sku":"BWCS-VPS140SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VPS140SL-1.webp?v=1778616006","url":"https:\/\/batteryweb.com\/products\/velleman-hps140-replacement-battery-48v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
