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.

LEXY X7 — 28.8V Li-ion Replacement Battery (T-DC49L-MUR)
This is a 28.8V, 2500mAh Li-ion replacement battery for the LEXY X7 cordless vacuum cleaner. It fits directly into the X7 handheld unit and restores full suction power when the original cell has degraded. Use the OEM part number T-DC49L-MUR to confirm fitment before ordering.
- X7 platform fit: The LEXY X7 runs a 28.8V motor rail with a BMS that monitors cell voltage and current draw. This replacement cell matches that voltage requirement and uses the same connector and BMS handshake profile as the original T-DC49L-MUR pack.
- Bench tested on actual hardware: We ran this cell under sustained suction load and through filter-restriction cycles. The BMS held the cutoff threshold correctly and recovered cleanly after an overcurrent trip — no manual reset needed.
- Dock charging practice for the X7: Do not leave the X7 sitting on the charging dock indefinitely. Continuous trickle charging accelerates capacity fade in Li-ion packs faster than normal cycle wear. Charge to full, then remove the vacuum from the dock.
Suction dropping before the battery indicator shows low
This is a voltage sag issue, not a dead cell. When the X7 motor draws high current — on carpet, upholstery, or through a partially blocked filter — cell voltage drops momentarily below the threshold the BMS tolerates. The motor throttles back to protect the pack. A clean filter cuts motor draw significantly and is the first thing to check when suction feels weak on a charged battery.
Motor cutting out mid-clean and then recovering on its own
This is a BMS overcurrent trip caused by sustained restricted airflow — usually a clogged filter or blockage in the suction path. The motor pulls more current than the BMS allows, so it cuts power to protect the cells. After a few seconds the BMS resets and the motor restarts. Clear the filter and check the suction path before assuming the battery is faulty. If the trips stop after cleaning, the battery is fine.

Frequently Asked Questions
My LEXY X7 loses suction well before the battery light comes on — is the new battery doing the same thing?
That symptom is usually a motor voltage sag under load, not a battery failure. When the filter is partially blocked, the motor pulls more current than rated, and the BMS briefly throttles output to protect the cells — suction drops even though charge is still there. Clean the filter first and retest. If suction holds steady after that, the battery is working correctly.
The X7 cuts out for a few seconds mid-clean, then powers back on by itself — what's causing that?
That's a BMS overcurrent trip. Restricted airflow forces the motor to draw a sustained spike of current above the pack's threshold, so the BMS shuts off power momentarily and then resets. Check the filter, the dirt cup seal, and the suction path for any blockage. Once airflow is clear, the current draw drops back into range and the trips stop.
I left the X7 on the dock between cleans and the new battery already feels weaker — did I get a bad cell?
Continuous dock charging is the most common cause of early capacity fade in Li-ion cordless vacuums. The charger keeps the pack at or near full charge indefinitely, which stresses the cells at high state-of-charge and accelerates degradation faster than normal use cycles would. Remove the X7 from the dock once charging is complete. Charge only when the battery is genuinely depleted and the difference should be noticeable within a few cycles.
