It fits the EGS1A1, EGS1A4, and EGS6 models. When the original cell degrades and the vacuum loses suction or won't hold a charge, this cell restores full function without replacing the unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEGS1A1, EGS1A4, and EGS6 compatibility:\u003c\/strong\u003e\n    These three models share the same 3.6V single-cell Ni-MH platform and connector footprint. The battery housing dimensions (66.57 × 44.30 × 22.17 mm) match the original bay. No modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the EGS1A1 charging circuit and confirmed the BMS accepted charge without error. Discharge held steady at rated voltage under motor load across multiple runs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline on these vacuums:\u003c\/strong\u003e\n    Disston handheld vacuums are frequently left on the charging dock between uses. Ni-MH cells in this voltage class degrade noticeably faster under continuous trickle charge. Charge fully, then remove from the dock until the next use.\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\"\u003eOn the EGS series vacuums, suction loss often happens well before the battery indicator signals low. A partially clogged filter forces the motor to draw above its rated current, pulling the cell voltage down faster than the indicator circuit accounts for. The result reads as battery failure when the actual cause is airflow restriction. Clear the filter and retest — if suction recovers to full strength, the cell is fine. If suction stays weak on a clean filter, check that the cell rests above 3.2V under load before replacing it.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use then recovering after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis cut-and-recover pattern is a BMS overcurrent trip, not a dead battery. It happens when sustained suction restriction — a blocked nozzle, compressed filter, or hair-wrapped roller — pushes motor draw past the cell's protection threshold. The BMS disconnects, the motor stops, and the pack resets after the load clears. Fix the restriction first. If the motor still trips on a clear airflow path, the cell's internal resistance has climbed high enough that normal motor-start current triggers the cutoff — at that point the cell needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428056596570,"sku":"BWCS-HVS110VX-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428056629338,"sku":"BWCS-HVS110VX-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428056662106,"sku":"BWCS-HVS110VX-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HVS110VX_1.webp?v=1779934015","url":"https:\/\/batteryweb.com\/products\/disston-egs1a1-replacement-battery-36v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
