It replaces OEM part numbers 482-BH3PER, 552096, OM11484, and SPK-DFX2-158. Capacity is 2000mAh (9.6Wh) — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eForce DFE and DFS series compatibility:\u003c\/strong\u003e\n    These gauges share the same battery compartment dimensions, connector pinout, and 4.8V supply rail. The BMS handshake is identical across the DFE, DFS, DFS-R, and SPK-DF-112 variants, so one pack covers all four platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Force DFE measurement firmware under sustained tension and compression logging. The BMS held voltage steady through repeated peak-load events at sensor initialisation, and the charge circuit accepted a full charge cycle without thermal cutoff or fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCalibration cycle before first field use:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the instrument menu before deploying it on-site. The Force DFE maps battery state during calibration — skipping this step causes the gauge to throw premature low-battery warnings during your first measurement session, even with a fully charged pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the Force DFE sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge over time. If the gauge has been shelved for several months, the pack voltage can drop below the BMS recovery threshold — typically around 3.6V for a 4-cell 4.8V Ni-MH pack. When this happens, the charger may not initiate a charge cycle because the BMS reads the pack as faulty rather than deeply discharged. The fix is to apply a low-current trickle charge for 15–30 minutes to bring the pack above the recovery threshold before connecting to the standard charger. Once voltage clears 4.0V, the normal charge cycle will start.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eForce DFE shuts down mid-measurement during a logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity failure. Under sustained sensor load during continuous data logging, the combined draw from the display, measurement circuit, and USB output can pull voltage below the instrument's cutoff threshold momentarily — even when the pack shows adequate charge at rest. Aged Ni-MH cells with elevated internal resistance sag harder under this combined load than a fresh pack will. Replacing the pack resolves the dropout; after installation, confirm resting voltage reads at or above 5.0V before starting a logging session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360606060634,"sku":"BWCS-CFD112SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360606093402,"sku":"BWCS-CFD112SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360606126170,"sku":"BWCS-CFD112SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CFD112SL-1.webp?v=1778615989","url":"https:\/\/batteryweb.com\/products\/chatillon-force-dfe-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
