It uses OEM part number 29562 and slots directly into the same battery bay. Voltage and capacity match the original spec to keep your instrument functional in the field.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMesa Pro and Mesa Pro 10\" compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V battery architecture, connector pinout, and BMS handshake protocol — a single cell design covers the full Mesa Pro lineup without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the Mesa Pro platform. The BMS negotiated correctly with the instrument's power management controller, and cell voltage held stable under sustained GNSS acquisition load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the Mesa Pro's instrument menu before heading to site. The instrument maps battery state during that routine — skip it, and the battery percentage indicator will throw premature low-battery warnings on your first survey session.\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 a Mesa Pro sits unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in survey instruments self-discharge during storage. If the Mesa Pro sits unused long enough, cell voltage can drop below the BMS recovery threshold — typically around 2.5V per cell — and the pack enters a protective sleep state. At that point, the instrument shows no charge response and the battery appears dead even with a charger connected. To recover it, apply charge at a low current rate for 10–15 minutes before the BMS will accept a normal charge cycle. If voltage has dropped below 2.0V per cell, the pack is outside recovery range and needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMesa Pro shuts down mid-session with no low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when sustained sensor load — continuous GNSS tracking, active Bluetooth, and data logging running simultaneously — pulls enough current to trigger a momentary voltage sag below the BMS cutoff threshold. The pack is not empty; it is cutting out under combined draw. Older or partially degraded cells sag further under the same load, so the problem worsens as a battery ages. Check rested cell voltage at the battery terminals: if it reads below 13.8V after a full charge, the pack has capacity loss significant enough to cause this under field load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360438288474,"sku":"BWCS-JUM100XL-1","price":91.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43360438321242,"sku":"BWCS-JUM100XL-2","price":108.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43360438354010,"sku":"BWCS-JUM100XL-3","price":121.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JUM100XL-1.webp?v=1778614685","url":"https:\/\/batteryweb.com\/products\/juniper-mesa-pro-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
