Fits Royal Linea10 PDA; replaces OEM battery for this handheld data-collection device.
3.7V, 800mAh lithium-ion cell delivers 2.96Wh — matches original capacity for full field-shift operation.
Battery slides into the rear compartment with connector alignment to the main board socket.
We bench-tested this cell in the Linea10 boot sequence; BMS accepted the new pack on first insertion without fault codes.
Perform a full data sync to the host computer before removing the old battery — the Linea10 stores open files and application state in RAM powered solely by this cell, and removing power without syncing causes permanent data loss.

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

🔹 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.

Royal Linea10 — 3.7V Li-ion Replacement Battery

This is a 3.7V 800mAh lithium-ion replacement battery for the Royal Linea10 handheld mobile computer. It fits the Linea10 PDA used in data collection, field operations, and warehouse scanning workflows. Swap it in when the original cell no longer holds enough charge to get through a shift.

  • Linea10 platform fit: The Linea10 draws from a single-cell 3.7V lithium-ion architecture. This replacement matches that voltage rail and physical form factor, so the device's power management circuit sees what it expects on startup.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench, confirmed the BMS trips correctly at low voltage, and verified the protection circuit does not flag a fault on initial connection.
  • RAM data sync before swap: The Linea10 stores open application state and unsaved records in volatile RAM powered directly by the main battery. Sync all data to the host system before removing the cell — a full power loss clears anything not written to flash storage.

Linea10 not booting after a new battery is installed

A freshly manufactured lithium-ion cell often ships at a partial state of charge — sometimes below 3.5V. The Linea10's boot sequence draws a short current spike that a low cell cannot sustain, causing the device to stall or display nothing. Connect the battery to the charger for at least 30 minutes before attempting to power on. Once the cell reaches approximately 3.7V, the boot sequence completes normally.

Battery life noticeably shorter during active scanning sessions

Standby current on the Linea10 is low, but active barcode scanning and wireless radio transmission pull significantly more current per cycle. A worn original cell shows this gap first — adequate on idle, dead mid-session. This replacement provides a fresh 800mAh cell, restoring the capacity buffer that active scanning workflows consume. If life still seems short after a full first charge, check whether the wireless radio is set to always-on rather than on-demand.

Frequently Asked Questions

The Linea10 lost all my open records when I swapped the battery — is that normal?

Yes, and it happens because the Linea10 holds unsaved application data in SRAM, which is powered by the main battery. The moment the cell is removed, that RAM loses power and the data is gone — there is no backup capacitor to bridge the gap. Before any battery swap, use ActiveSync or the device's built-in sync utility to push all open records to the host computer. Once the new battery is seated and the device reboots, the data will be on the host ready to restore.

My Linea10 keeps dropping the wireless connection after fitting the new battery — what's wrong?

The Linea10's radio is voltage-sensitive and will throttle or drop its connection if the cell is not fully charged. A new battery often ships at a partial charge, which is enough to boot the device but not enough to sustain stable radio output. Charge the battery fully before running a wireless sync session. Check the charge indicator shows 100% and attempt the sync again — most drop issues resolve at a full 4.2V cell state.

The Linea10 powers on but freezes on the boot screen after the battery swap — how do I fix it?

A freeze on the boot screen usually means the cell voltage dipped below the threshold the device needs to complete its startup routine. The boot sequence reads flash storage and initialises the radio, both of which draw current — a low cell can't hold the voltage rail steady through that process. Connect to the charger and let the battery charge for at least 30 minutes without attempting to power on. Try booting again once the cell is above 3.7V.
