What this battery replaces

This is a new 46Wh lithium-ion battery rated at 14.4V, built to replace part numbers B41N1304, B41BK4Q, 0B200-00530000 and 4INP9/38/64. It fits a wide range of Asus VivoBook A451, K451, R451, R453, S451 and V451 series laptops. Owners of compatible models can swap the original pack without adapter changes.

Capacity under daily use

The 46Wh cell delivers a full charge at 14.4V and maintains output across typical office and media workloads. Lithium-ion chemistry limits voltage sag during sustained drain, so run-time stays consistent until the low-battery threshold. The pack is rated for 12 months of regular cycling.

Installation notes

The battery sits in the standard internal bay and connects via the existing multi-pin connector; no soldering or cable routing is required. Most models release the pack with one or two captive screws accessible from the bottom cover. Buyers whose laptop uses a different form factor or voltage should verify the part number before ordering.

Questions about this item

How much heat does the 14.4V 46Wh lithium-ion pack produce during all-day use?

The battery runs at its rated 14.4 volts and 46 watt-hours; normal operation generates only the warmth typical of a lithium-ion cell under load.

Which existing laptop models accept the B41N1304 without any extra parts?

It fits Asus VivoBook A451LA, A451LB, A451LN, K451LA, K451LB, K451L, R451LA, R451LB, R451LN, R453LA, R453LB, R453LN, S451LA, S451LB, V451LA, V451LB and V451LN series.

Will the 4INP9/38/64 replacement work alongside the original charger from an older VivoBook?

Yes, the 14.4V output matches the factory specification so the existing AC adapter charges the new pack normally.
