Replacement battery for LG G8 ThinQ and V40 series

This 3.4 Ah lithium-polymer cell replaces the original BL-T41 pack in LG G8 ThinQ and V40 ThinQ handsets. It matches the 3.85 V nominal voltage and 13.09 Wh energy rating of the factory unit. The 84.80 x 42.40 x 5.10 mm form factor fits the same internal cavity. Supplied new and 100 % OEM compatible.

Who this suits and who should look elsewhere

Owners of the listed LG models who need a fresh power source will find a direct fit. Buyers with other LG phones or different brands cannot use this cell. Anyone requiring a higher capacity than 3400 mAh must choose another product. The single black colour is the only finish offered.

Capacity and voltage confirm compatibility

The 3.4 Ah rating at 3.85 V delivers 13.09 Wh, matching the OEM specification for reliable runtime. Verifying that your device appears in the supported model list is the decisive step before purchase.
