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.

Muratec KDS ATL-X6 Series — 3.7V Li-Polymer Replacement Battery (LTB-3H)
This is a 3.7V, 3600mAh Li-Polymer pack built to the LTB-3H spec. It fits the ATL-X6, ATL-96RG, ATL-66RG, ATL-46RG, and three additional ATL-series data collectors used in field surveying and land measurement. Capacity figures come from the product data sheet, not third-party estimates.
- ATL-series data collector compatibility: These models share the same 3.7V power rail, LTB-3H connector footprint, and BMS handshake protocol. Swapping between compatible ATL units carries no voltage mismatch risk — the BMS negotiates state-of-charge the same way across the family.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on an ATL-series unit. The BMS held charge termination cleanly at full capacity, and the protection circuit responded correctly to the current spike that hits during GPS module initialisation at power-on.
- Field calibration before first deployment: After installing this pack, run a full calibration cycle through the instrument menu before heading to site. The ATL-series maps battery state during that calibration sequence — skipping it causes the instrument to throw premature low-battery warnings on your first measurement session.
BMS cutoff during GPS module initialisation on the ATL-X6
When the ATL-X6 powers on, the GPS and GNSS receiver draws a sharp current spike as it acquires lock — this happens in the first few seconds after boot. A degraded or deeply discharged pack can drop voltage fast enough under that load to trip the BMS overcurrent threshold. The unit shuts off immediately, which looks like a power-on failure rather than a battery issue. If the pack rests above 3.6V on a multimeter before install, the BMS should clear the spike without tripping.
ATL-series data collector shuts down mid-logging session without a low-battery warning
During a sustained logging session, the combined draw from GPS lock, sensor polling, and display backlight can pull the pack voltage down steadily under load. If the pack's internal resistance has increased — common after prolonged storage or cell age — the voltage sag under that sustained load crosses the BMS undervoltage cutoff before the display indicator reaches the low-battery threshold. The instrument shuts off without warning because the indicator was reading resting voltage, not loaded voltage. Charge the pack fully to 4.2V and let it rest 10 minutes before the session to confirm resting voltage is stable.

Frequently Asked Questions
The ATL-X6 won't charge this new pack — the charging indicator just blinks and stops after a few seconds. What's happening?
This is a BMS sleep-mode lockout. If the pack voltage dropped below roughly 2.5V during storage, the protection circuit disables charge input to prevent unsafe charging of an over-discharged cell. Connect the pack to the charger and leave it for 20–30 minutes without interrupting — some chargers apply a low trickle current that slowly wakes the BMS before full charge begins. If the indicator stabilises and charging resumes, the pack has recovered. If it doesn't recover after 30 minutes, check that the charger output is reaching the battery contacts with a multimeter.
Readings on the ATL-96RG drift or reset partway through a logging session even though the battery shows charge remaining on the display.
This points to voltage dropout under sustained sensor load, not total capacity failure. The display reads resting cell voltage, but during active GPS polling and data logging the pack is under continuous draw — if internal resistance is elevated, voltage sags enough to cause a momentary brownout that resets the logging state. The fix is to confirm the pack charges to a stable 4.2V and holds that resting voltage after a 10-minute rest off the charger before you start the session.
The ATL-X6 powers on fine but shuts off the moment I connect it to a PC for USB data transfer. Is that a port fault?
It's not the port — it's combined load. USB data transfer activates the serial interface controller at the same time the GPS module and display are running, and the total draw spikes sharply. If the pack is not at full charge, or if resting voltage is below 3.8V, that spike pulls loaded voltage below the BMS cutoff and the unit shuts off. Charge the pack fully before any USB transfer session and verify the resting voltage reads at or above 3.9V before connecting the cable.
