It replaces the original pack when the existing cell no longer holds a charge or capacity has dropped noticeably. Dimensions are 69.60 × 37.50 × 37.20mm — confirm these against your existing pack before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGYRO LASER 2500 fitment:\u003c\/strong\u003e\n    The 14.4V rail and physical form factor match the GYRO LASER 2500 battery bay directly. The BMS in this pack communicates with the vacuum's charge circuit at the same voltage threshold the motor controller expects on start-up.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under sustained motor load and confirmed the BMS holds the 14.4V rail steady through full draw cycles. The protection circuit tripped correctly at overcurrent and recovered cleanly on reset — no false cutoffs under normal suction load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the GYRO LASER 2500:\u003c\/strong\u003e\n    Do not leave this vacuum on the charging dock continuously after the pack reaches full. Cordless vacuums on permanent dock charge develop capacity fade faster than those charged only when depleted. Charge to full, then remove from the dock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than rated — typically caused by a partially blocked filter, not a failing battery. The BMS reads an overcurrent condition and pulls back power to the motor before the cell is actually depleted. Clear the filter first and retest. If suction restores to normal, the pack is fine — the filter was forcing the motor to work harder than the BMS allows.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use and then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead cell. When restricted airflow causes sustained high motor draw, the protection circuit cuts output to prevent cell damage. The pack recovers once temperature drops and the BMS resets. Check the filter and brush roll for blockages, clear them, and confirm the motor runs continuously at full suction — if it does, the cutout was restriction-driven, not a fault in the battery itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426414395482,"sku":"BWCS-ZCX510VX-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426414428250,"sku":"BWCS-ZCX510VX-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426414461018,"sku":"BWCS-ZCX510VX-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZCX510VX-1.webp?v=1779933223","url":"https:\/\/batteryweb.com\/products\/di4-gyro-laser-2500-replacement-battery-144v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
