Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Leica Disto S910 / D810 Series — 3.7V Li-ion Replacement Battery (795460)
This 3.7V 2600mAh Li-ion battery fits the Leica Disto S910, Disto D810, and Disto D810 Touch laser distance meters. These are handheld surveying instruments used for measuring distances, areas, and angles in field and construction environments. Voltage and cell format match OEM part numbers 795460 and 806678.
- S910, D810, and D810 Touch compatibility: All three models share the same battery bay dimensions, connector pinout, and BMS communication protocol. The S910 adds digital angle measurement, but the power rail and charge circuit are identical across this series.
- Bench tested on actual hardware: We ran this pack through the S910's full startup sequence, including point-cloud capture and Bluetooth pairing. The BMS held steady through sensor initialisation and sustained angle-measurement logging without triggering a protection cutoff.
- Post-install calibration on the Disto S910: After fitting this battery, run a full calibration cycle through the instrument menu before field deployment. The S910 maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session out on site.
BMS lockout after the Disto sat unused in a carry case for months
Li-ion cells self-discharge slowly during storage. If the Disto S910 or D810 sits unused for several months, the pack can drop below the BMS recovery threshold — typically around 2.5V per cell. At that point, the BMS enters a protection lockout and the instrument will not power on or respond to charging. Connecting the charger for 15–30 minutes at a low input current is usually enough for the BMS to detect a safe voltage floor and re-initialise. If the charger shows no activity after 30 minutes, the pack has discharged below the recovery window entirely.
Disto S910 shuts off mid-session during USB data transfer to a PC
USB data transfer activates the instrument's radio module, display backlight, and file-system controller simultaneously. That combined draw pulls more current than laser measurement alone, and a partially degraded cell can sag enough in voltage to trigger the BMS undervoltage cutoff. The instrument powers off cleanly rather than freezing or corrupting data — but the transfer fails. Charge the pack fully before any transfer session, and check that the cell voltage reads at or above 3.9V at the instrument's battery status screen before connecting the USB cable.

Frequently Asked Questions
My Leica Disto S910 powers on fine but shuts down the moment I start a USB transfer to my laptop — why?
USB transfer activates the display, file controller, and wireless module at once — the combined current draw spikes higher than standard measurement mode. If the cell has any capacity fade, voltage sags under that load and the BMS cuts the output to protect the cell. This isn't a firmware fault; it's the battery struggling under a peak draw it can no longer sustain. Charge fully and confirm the instrument's battery indicator reads full before initiating any transfer.
My replacement Disto battery won't charge at all after the instrument sat in the case all winter — is the pack dead?
Not necessarily. Extended storage drains Li-ion cells below the BMS recovery threshold, around 2.5V per cell, and the BMS locks out to prevent damage. Leave the charger connected for 20–30 minutes — a healthy BMS will detect the trickle input and re-initialise once it confirms a safe voltage floor. If the charger LED shows no activity at all after 30 minutes, the cell has discharged past the point of recovery and the pack needs replacing.
The Disto S910 battery percentage jumps or resets erratically on the display after I fit a new pack — what causes that?
The S910's voltage-threshold indicator is calibrating itself to the new cell's discharge curve, and early readings before a full charge-discharge cycle are unreliable. The display interpolates percentage from voltage checkpoints that were tuned to the worn original cell, so the new pack reads inconsistently until the instrument has mapped the new curve. Run one complete charge from flat to full, then complete a full measurement session before trusting the percentage readout. After that first full cycle the display should track the new cell accurately.
