The B31N1726 is one of the more unusual batteries in the ASUS aftermarket \u2014 the same model number spans two completely different product lines with different target markets, different chassis designs, and different cable routing requirements. Understanding this structure is the single most important thing for wholesale buyers sourcing this SKU.<\/p>\n

Platform 1: VivoBook 15 X510 \/ S510 \/ F510 series<\/strong>
\nStudent and young professional mainstream notebooks released 2017\u20132018. Intel Core i5\/i7, slim aluminum chassis, productivity-focused. Battery uses a shorter cable routed to the upper-right corner of the bay.<\/p>\n

Platform 2: TUF Gaming FX504 \/ FX505 \/ FX80 \/ FX86 series<\/strong>
\nBudget gaming notebooks released 2018\u20132019. Intel Core i5\/i7 + NVIDIA GTX 1050\/1050 Ti\/1060, heavier chassis with active cooling. Battery uses a longer cable routed to the lower-left corner of the bay. This variant is also widely referenced by its alternate model codes B31BN91, B31BNEH, and A41LK9H<\/strong> \u2014 all refer to the same Shape B battery.<\/p>\n

Same B31N1726 model number. Same 11.52V \/ 48Wh electrical specification. Different spare part numbers. Different cable lengths. Not interchangeable.<\/strong><\/p>\n

The definitive identification method: open the back panel and read the spare part number on the original battery. 0B200-02760000 = Shape A (VivoBook). 0B200-02910000 or 0B200-02910200 = Shape B (TUF Gaming \/ B31BN91). When placing a bulk order, include this spare number and we confirm the correct variant before shipment.<\/p>\n

Why B31BN91 Searches Should Land on This Page<\/strong><\/p>\n

B31BN91 is the alternate designation printed on TUF Gaming FX platform batteries from certain production batches. Buyers searching specifically for B31BN91 are looking for the exact same Shape B battery covered here \u2014 the spare part number 0B200-02910000 cross-references both designations in ASUS’s parts system. Stocking B31N1726 Shape B covers every B31BN91 inquiry without maintaining a separate SKU.<\/p>\n

Why the TUF Gaming Platform Adds Meaningful Demand to This SKU<\/strong><\/p>\n

The FX504 and FX505 were ASUS’s entry-level gaming notebooks \u2014 priced at $600\u2013$900, they were the default “first gaming laptop” recommendation for budget-conscious buyers between 2018 and 2020. Gaming laptop batteries degrade faster than productivity notebooks: sustained GPU loads discharge cells at higher C-rates, and many gaming users charge while playing, keeping batteries at 100% SoC under heat for extended periods. The combination of high-stress use patterns and a now 5\u20137 year old installed base means the TUF platform generates battery replacement demand at above-average rates compared to same-age consumer notebooks.<\/p>\n
