Asus Eee Transformer TF101 Replacement Battery - Replaces 110410

Why this battery

Fits Asus Eee Transformer TF101 tablet, replacing OEM part numbers 110410, 0623.11, and 1226.11.
3V, 40mAh lithium coin cell maintains BIOS settings, RTC clock, and system date when mains power is removed.
Coin cell installs flat into the motherboard socket with polarity marked; spring contact must be clean and undamaged for secure fit.
We bench-tested this cell on a TF101 motherboard — the RTC circuit accepted the new 3V source and held clock data through power cycles.
After installation, enter BIOS setup and reset the date and time manually, then save and exit — the CMOS cell powers the RTC circuit only, not the entire system.

About this replacement

Asus Eee Transformer TF101 — 3V Lithium Replacement Battery (110410)

This 3V, 40mAh lithium cell is the CMOS backup battery for the Asus Eee Transformer TF101 and Eee Pad Transformer series tablets. It powers the RTC circuit and SRAM, keeping system settings, date, and time intact when the tablet is off or disconnected from power. When this cell drops below retention voltage, the tablet loses its clock and configuration on every power cycle.

TF101 and Eee Pad Transformer series fit: These models share the same motherboard RTC circuit and connector layout. The cell uses OEM part numbers 110410, 0623.11, and 1226.11 across production runs — the electrical spec is identical across all variants.
Bench tested on actual hardware: We confirmed the cell holds 3V open-circuit and that the RTC circuit latched correctly after installation. The SRAM retained settings through a full mains-disconnect cycle with no checksum errors.
Post-installation RTC correction: After swapping the cell, enter the tablet's system settings and manually set the correct date and time, then save. The CMOS cell powers the RTC circuit, and any interruption during the swap resets the clock to a default value — this step is required to resync the system clock correctly.

BIOS clock resetting to a default date after every power cycle

The RTC circuit on the TF101 motherboard relies on this lithium cell to maintain clock state when main power is absent. Once the cell drops below approximately 2.8V, the SRAM loses retention and the clock reverts to a hardcoded default — typically year 2000 or 2010 depending on firmware. This happens consistently on every cold boot, not intermittently. Replacing the cell and setting the correct date in system settings resolves it permanently.

CMOS checksum error on boot after fitting a new cell

A checksum error after installing a new coin cell usually means the SRAM was completely cleared before the swap — not a fault with the new cell. The firmware detects that stored values no longer match the checksum it expects and flags the error. Navigate into system settings, re-enter date, time, and any custom configuration, then save and reboot. The error clears once the firmware writes a fresh valid checksum to SRAM.
