The GSB-LHR is a portable seismic data logging unit used in oil and gas surveys, geotechnical investigations, and earthquake monitoring deployments. Voltage and capacity match the OEM specification exactly — 3.7V nominal, 800mAh (2.96Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGSB-LHR and Line Health Recorder fit:\u003c\/strong\u003e\n    Both designations refer to the same instrument platform. The cell format — 49.80 × 34.00 × 5.60mm — matches the internal battery bay, and the BMS handshake operates on the same voltage rail as the original pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through sensor initialisation events and sustained logging loads. The BMS held without tripping on the current spike at probe power-up, and voltage remained stable under continuous acquisition draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle through the instrument menu before field deployment. The GSB-LHR maps battery state during calibration — skipping this step causes premature low-battery warnings during the first active logging session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during seismic sensor initialisation on the GSB-LHR\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the GSB-LHR powers up a connected geophone or sensor string, it draws a short surge current to initialise the probe circuit. A worn or deeply discharged cell can't sustain that spike, and the BMS trips as a protection response — cutting power instantly. This looks like the instrument shutting off at startup, not a charging fault. The replacement cell's fresh capacity handles the initialisation surge without the voltage rail collapsing below the BMS cutoff threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGSB-LHR not recognising a new pack after the unit sat in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the GSB-LHR sat unused long enough, the cell voltage can drop below the BMS re-initialisation threshold — typically around 2.5V — and the pack enters sleep mode. The instrument then fails to detect any battery at all, or shows a battery error on screen. To recover, connect the charger and leave it for 15–20 minutes before attempting to power on; most BMS circuits re-initialise once the cell rises above 2.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360434716762,"sku":"BWCS-GLH454SL-1","price":307.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360434749530,"sku":"BWCS-GLH454SL-2","price":367.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360434782298,"sku":"BWCS-GLH454SL-3","price":412.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GLH454SL-1.webp?v=1778614685","url":"https:\/\/batteryweb.com\/products\/geospace-gsb-lhr-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
