The FG-3000 is a handheld push\/pull measurement instrument used in quality control, inspection, and lab testing. This cell restores full display and measurement function when the original pack no longer holds charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFG-3000 force gauge fit:\u003c\/strong\u003e\n    The FG-3BAT is a compact 30.60 × 31.00 × 11.00mm Ni-MH cell matched to the FG-3000's internal bay dimensions and 3.6V supply rail. The connector and BMS communication profile align with the gauge's charge management circuit — no modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the FG-3000's charge cycle and confirmed BMS handshake, stable voltage delivery under measurement load, and correct low-battery threshold triggering on the display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCalibration cycle before field use:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle through the FG-3000's instrument menu before taking measurements. The gauge maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFG-3000 BMS lockout after the gauge sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge slowly even when the instrument is off. If the FG-3000 sits unused long enough, the pack drops below the BMS recovery threshold and the gauge will not power on or accept a charge. Connect the gauge to its charger and leave it for 30–60 minutes — the BMS needs to see a trickle input before it opens the charge circuit. If the original pack has been in storage more than six months, recovery is often not possible and replacement is the faster path.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings resetting or dropping to zero mid-logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when sustained sensor load pulls the cell voltage below the FG-3000's operating floor — not a full shutdown, but a momentary dropout that resets the active reading. A worn cell holds its resting voltage but collapses under load. A fresh FG-3BAT pack at 3.6V holds the supply rail steady through a continuous logging run. After fitting the replacement, confirm resting voltage reads at or above 3.6V before starting a logged session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360485179482,"sku":"BWCS-SDG300SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360485212250,"sku":"BWCS-SDG300SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360485245018,"sku":"BWCS-SDG300SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDG300SL-1.webp?v=1778615900","url":"https:\/\/batteryweb.com\/products\/shimpo-fg-3000-replacement-battery-36v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
