It replaces OEM part number 90558173 directly. The battery restores full motor power to a vacuum that has lost suction strength or stopped holding charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCHV1510 platform fit:\u003c\/strong\u003e\n    The CHV1510 and 15.6V DustBuster share the same cell configuration, connector pinout, and BMS communication protocol. Swapping the pack does not require any modification — the charger handshake runs identically on replacement cells.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the CHV1510 motor draw cycle under simulated filter restriction. The BMS held steady through repeated high-draw bursts and did not trip prematurely. Capacity returned to rated output after three full charge-discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the CHV1510:\u003c\/strong\u003e\n    Do not leave the DustBuster sitting on the charging dock permanently. Continuous trickle charging is the fastest way to degrade Ni-Cd cells in this unit. Charge to full, remove from the dock, and return it only when the vacuum noticeably weakens.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping well before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-Cd cells in the CHV1510 are voltage-sensitive under motor load. As cells age, internal resistance climbs — under suction load the voltage sags enough to reduce motor speed, even though resting voltage still reads acceptable. The battery indicator reads resting voltage, not load voltage, so it lags behind real performance. A new pack at rated capacity eliminates the sag — load voltage stays above the 12V threshold the motor needs for full RPM.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a motor fault. When the CHV1510 filter is partially blocked, the motor strains harder to maintain airflow and draws current above the BMS protection threshold. The BMS cuts the circuit, the motor stops, and after a brief cooldown the pack resets and power returns. Clearing the filter drops the draw back to normal operating current — typically below 3A — and the cutout stops. If the cutout persists with a clean filter, the original cells have degraded enough that internal resistance is amplifying the apparent load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427953868890,"sku":"BWCS-BKV151VX-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427953901658,"sku":"BWCS-BKV151VX-2","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427953934426,"sku":"BWCS-BKV151VX-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKV151VX-1.webp?v=1779933418","url":"https:\/\/batteryweb.com\/products\/blackdecker-156v-dustbuster-replacement-battery-156v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
