Nokia 3 V WT241 Compatible Battery 3.8V 3800mAh

Nokia 3 V / TA-1153 — 3.8V Li-Polymer Replacement Battery (WT241)

This 3.8V, 3800mAh lithium-polymer cell replaces the original WT241 battery in the Nokia 3 V (TA-1153) smartphone. It restores power to a phone that no longer holds a charge, shuts down unexpectedly, or won't turn on after extended use. Dimensions are 81.30 × 64.60 × 4.50mm — same footprint as the factory cell.

• Nokia 3 V / TA-1153 fit: Both model designations run the same motherboard revision and battery connector pinout. The WT241 part number covers both, so one cell works across the full production run of this phone.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Nokia 3 V platform. The BMS accepted the cell without fault codes, and the charge IC reached full termination voltage correctly on the first cycle.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle. This gives the fuel gauge IC accurate data points against the new cell's discharge curve before high-current charging begins on an uncalibrated cell.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff problem, not a capacity problem. When the modem fires during a call or the screen brightness spikes, instantaneous current draw pulls the cell voltage below the BMS cutoff threshold — even though the reported state of charge looks fine. A new cell paired with an old fuel gauge IC that is still calibrated to the worn cell's curve will misread remaining charge by a significant margin. One full discharge to automatic shutdown, followed by a full charge to 100%, resets the coulomb counter and aligns the IC to the new cell's actual voltage curve.

USB charging not recognised on first plug-in after replacement

Some Nokia 3 V units will not begin charging immediately after a cell swap if the battery voltage is below approximately 3.0V — the charge IC enters trickle pre-charge mode and the OS may show no charging indicator at all. Leave the phone connected via the original cable for 10–15 minutes without interaction. Once the cell climbs above the pre-charge threshold, the IC switches to full constant-current charge and the screen indicator updates. If the phone still shows nothing after 20 minutes, try a different USB-C cable before assuming a fault with the cell.
