It also fits TDS data collectors and the H-075-335-200R-032 configuration. Cross-references include XHR-4\/3AUX, HR4\/3AU-F4C, A075-2003, and E-0191.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTSCe and GIS TSCe compatibility:\u003c\/strong\u003e\n    These models share the same 4.8V four-cell NiMH pack format, battery bay connector, and charge termination logic. The controller uses delta-V detection to end charging — cell count and chemistry must match exactly, which is why this specific pack works where generic alternatives fail BMS handshake.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the TSCe charge and discharge sequence and monitored the delta-V cutoff response. The BMS terminated charge cleanly at capacity without false cutoffs. Discharge held voltage above the low-battery threshold through sustained GPS logging load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment calibration on the TSCe:\u003c\/strong\u003e\n    After installing, run a full calibration cycle through the TSCe instrument menu before heading to site. The controller maps battery state during that cycle — skip it and the low-battery warning will fire early on your first field 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\"\u003eTSCe shutting down mid-measurement with the battery showing charged\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TSCe draws a short current spike when it powers a connected GPS receiver or external sensor module. An aged or degraded cell cannot sustain voltage through that spike — the pack voltage collapses briefly and the controller interprets it as a dead battery and shuts down. A fresh 4000mAh Ni-MH pack holds internal resistance low enough to ride through that initialisation surge. If this is happening on a new pack, verify the battery contacts in the bay are clean and making full contact — oxidised contacts add resistance that mimics a weak cell under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTSCe display showing erratic battery percentage after reboot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TSCe voltage-threshold indicator recalibrates to new cells over the first few charge cycles — this is normal and not a fault with the pack. On a freshly installed Ni-MH battery, the controller has no reference history for the new cell's voltage curve, so percentage readings jump or reset inconsistently at startup. Run two full charge-to-discharge cycles through normal field use and the readings stabilise. If erratic readings persist past three cycles, check that the battery bay cover is seating fully — a partial connection causes intermittent voltage drops that prevent the controller from reading the pack accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360790872154,"sku":"BWCS-TRM335SL-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360790904922,"sku":"BWCS-TRM335SL-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360790937690,"sku":"BWCS-TRM335SL-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRM335SL-1.webp?v=1778616277","url":"https:\/\/batteryweb.com\/products\/trimble-tsce-replacement-battery-48v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
