Compatible LG LW25-B3HD RTC Battery

This lithium CMOS battery replaces the original RTC cell in LG LW25-B3HD laptop motherboards. It is a new component tested before shipping and intended for motherboard real-time-clock power, not for main system power.

Sustained Low-Current Operation

The cell delivers the steady microampere current required to keep BIOS settings and the system clock alive while the laptop is off or unplugged. Its lithium chemistry maintains a stable voltage over years of continuous trickle discharge rather than high-drain bursts.

Lithium Coin-Cell Interface Limits

The battery fits the standard two-pin header spacing used on the target motherboard, so no soldering or adapter is needed. Polarity must match the board marking; reversing it will prevent the real-time clock from functioning. Buyers who need a main laptop battery or a different form-factor cell cannot use this part.

Questions about this item

Does the lithium CMOS battery draw noticeable power or generate heat when the laptop runs all day?

The lithium CMOS battery only powers the real-time clock and BIOS memory when the laptop is off; it draws negligible current and produces no perceptible heat during daily use.

What must I already have for this DBTLAP battery to work in my LG LW25-B3HD?

You need the LG LW25-B3HD laptop with a compatible motherboard header; the package includes one CMOS battery and nothing else.

Will this replacement CMOS battery function alongside the original LG motherboard components I am keeping?

Yes, it is a direct replacement for the LG LW25-B3HD CMOS RTC battery and is tested before shipping to ensure compatibility with the existing motherboard.
