Rated at 5100mAh (37.74Wh), it slots into the same battery bay without modification. The Yuma is a field-hardened handheld computer used in surveying, GPS, and GIS workflows where a dead battery mid-session is a real operational problem.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYuma platform compatibility:\u003c\/strong\u003e\n    The Yuma series runs a shared battery architecture across its variants — same voltage rail, same connector pinout, same BMS communication protocol. This pack covers the full lineup listed above because they all draw from the same 7.4V supply and expect identical BMS handshake signals.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the Yuma platform and confirmed the BMS negotiated correctly with the device charge IC. The pack held voltage across the draw profile of active GPS tracking with display on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run the Yuma down to automatic shutoff under normal field use, then charge uninterrupted to 100%. The fuel gauge IC calibrates against the new cell during that first complete cycle — skipping it leaves the percentage display inaccurate from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eYuma shutting down at 15–25% remaining after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Yuma's power management layer uses a stored discharge curve to predict remaining capacity. When a new cell goes in, that curve no longer matches the actual cell chemistry and voltage response. As the new battery drops through the 3.5–3.6V per cell range, the device sees what looks like a steep voltage cliff and triggers a protective shutdown before the cell is actually empty. Running one full discharge-to-shutoff cycle followed by a full uninterrupted charge resets the stored curve and stops the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eYuma showing 100% charge but percentage drops faster than expected within the first hour\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is fuel gauge drift — the measurement IC is still referencing calibration data from the old cell and misreports the initial state of charge. The pack itself is not depleted; the reported number is wrong. One complete discharge to automatic shutoff followed by a full charge to 100% forces the gauge IC to resample the new cell's capacity endpoints. After that cycle, the percentage reading tracks accurately through the full discharge range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425843675226,"sku":"BWCS-TRS600SL-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425843707994,"sku":"BWCS-TRS600SL-2","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425843740762,"sku":"BWCS-TRS600SL-3","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRS600SL-1.webp?v=1779929976","url":"https:\/\/batteryweb.com\/products\/trimble-yuma-replacement-battery-74v-5100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
