These are professional survey instruments used for precision distance, area, and volume measurement on active job sites. Capacity figures come from the product data — 3400mAh \/ 12.58Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDisto S910, D810, and D810 Touch compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay geometry, connector pinout, and BMS handshake protocol. The S910 adds Wi-Fi and Bluetooth modules, which draw additional standby current — this cell's capacity covers both the base measurement functions and the active radio stack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Disto S910's power-on sequence, triggered the laser, and activated the P2P Wi-Fi link simultaneously. The BMS held the supply rail steady through each combined draw event without tripping the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Disto:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle through the instrument's settings menu before field deployment. The Disto maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even with a fully charged cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDisto S910 BMS lockout after the instrument sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and if the pack drops below roughly 2.5V per cell, the BMS enters a protective sleep state and refuses to accept a standard charge. The Disto S910 cannot wake a locked BMS through its own charging circuit — the charger simply sees no response and stops. To recover, apply a low-current pre-charge (often called trickle or recovery mode) using a bench charger set to 0.1C until the cell climbs above 3.0V, then switch to normal charge. Once above 3.0V per cell, the BMS reactivates and the instrument will recognise the pack normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDisto shuts down the moment USB data transfer to a PC begins\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the Disto initiates a USB data transfer, the instrument powers its USB controller, keeps the display active, and sustains the measurement module — combined draw spikes sharply above normal operating current. A degraded original cell with elevated internal resistance cannot hold the voltage rail through that combined load, so the BMS cuts output to protect the cell and the device resets. A fresh cell with lower internal resistance maintains the supply voltage above the Disto's minimum threshold throughout the transfer. Fit the new battery, allow a full charge to 4.2V, then attempt the transfer again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360461455450,"sku":"BWCS-LCS910XL-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360461488218,"sku":"BWCS-LCS910XL-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360461520986,"sku":"BWCS-LCS910XL-3","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LCS910XL-1.webp?v=1778615883","url":"https:\/\/batteryweb.com\/products\/leica-disto-s910-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
