🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Revive your LG Prada 3.0 or compatible device with this BL-44JR 1540mAh replacement battery. Released in 2011-2012, the LG Prada 3.0 (P940) was a landmark collaboration between LG and the iconic Italian fashion house Prada — one of the earliest premium fashion-branded smartphones. It featured a sleek, minimalist design with a 4.3-inch NOVA IPS display, dual-core processor, and a distinct black-and-white Prada-themed user interface. The SU540 and KU5400 were Korean market variants with similar specifications. This Li-ion battery restores the full 1540mAh capacity, bringing back reliable daily power for these classic devices. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why Keep Your Prada Phone Alive — And Why Battery Replacement Matters: The LG Prada 3.0 holds a special place in smartphone history as one of the first designer fashion phones. Its unique Prada UI, minimalist hardware keys, and premium materials made it a collector’s item for tech enthusiasts and fashion-conscious users alike. However, after 12-14 years, the original BL-44JR battery has almost certainly degraded beyond useful life. Common symptoms include: the phone not turning on at all, shutting down immediately after unplugging, draining from full charge in under an hour, or swelling of the original battery. This BL-44JR replacement battery restores the original 1540mAh capacity, allowing these vintage devices to function as working collector’s items, backup phones, or minimalist devices for calls and texts. The Prada 3.0’s 4.3-inch display was one of the brightest and most readable of its era, and the phone’s compact size makes it an appealing choice for users seeking a break from large modern smartphones. The BL-44JRH variant uses the identical battery cell with slightly different packaging — both are fully interchangeable. This battery provides approximately 3-4 hours of talk time, 8-10 hours of music playback, and 2-3 days of standby time on the Prada 3.0, matching the performance of the original battery when new.
Compatibility Note: Fits LG Prada 3.0 (P940), LG Prada K2, LG SU540, and LG KU5400. BL-44JR and BL-44JRH are fully interchangeable — both codes refer to the same 1540mAh, 3.7V Li-ion battery. Please confirm your original battery model before ordering — BL-44JR or BL-44JRH printed on your existing battery. This battery is NOT compatible with LG Prada (first generation), LG Prada II (second generation), or other LG models that use different battery model numbers. Always check the battery label inside your phone’s compartment before purchasing.
