The Neo 1 heats to working temperature in 15 seconds and cycles through up to 200 gluing applications on a charge — both of which depend on the battery holding stable voltage under repeated thermal load. Capacity and voltage match the original unit exactly.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNeo 1 compatibility:\u003c\/strong\u003e The Neo 1 runs a single-cell 3.7V Li-ion architecture with a micro USB charge input — this battery matches that voltage rail, cell format, and BMS communication so the gun charges and fires without modification.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles on the Neo 1 — the BMS held voltage steady under repeated heating element activation and cut off cleanly at the low-voltage threshold.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCharge at any level, no ritual needed:\u003c\/strong\u003e Li-ion cells in this voltage class have no memory effect — plug in via micro USB whenever it's convenient without waiting for a full discharge first.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHow the heating element taxes a single-cell Li-ion pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Neo 1's heating element draws a concentrated burst of current every time it cycles to temperature. A single 3.7V cell has no parallel cells to share that load, so cell quality and BMS headroom matter more here than in multi-cell packs. This replacement uses a cell rated for the current demands of a resistive heating element, not just light-duty electronics. The BMS monitors temperature and voltage simultaneously to prevent stress during rapid heat cycles.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGun heats up but cuts out mid-use — what's happening and how to fix it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Neo 1 fires up normally then shuts off during a gluing session, the cause is usually low-voltage cutoff triggering under load — not a dead battery. An aged or depleted cell sags in voltage the moment the heating element draws current, tripping the BMS protection. Fitting a fresh cell with full capacity restores the voltage headroom the BMS needs to stay open under load. Charge the new battery fully before first use to confirm normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175821148250,"sku":"BWCS-WGF300VX-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175821181018,"sku":"BWCS-WGF300VX-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175821213786,"sku":"BWCS-WGF300VX-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WGF300VX-1.webp?v=1775236276","url":"https:\/\/batteryweb.com\/products\/steinel-neo-1-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
