Review: Do NOT buy for Asus K501UW! - While the title and description claim it fits an Asus K501UW, it does not. The wires are too long to comfortably fit where the battery plugs into the motherboard, and the side with the black wires doesn't sit flush to the battery port and thus causes the battery to pop off and disconnect. Plus, it's really difficult to see whether or not the connections are flat and flush when the original OEM battery has a white connector and this one is black. I let charge for a full 12 hours and had nothing but problems with the battery upon install, with my Asus K501UW rejecting the battery as non-existent and refusing to give a percentage readout. Eventually, after going through all the software tricks I could (including completely updating the BIOS and the battery drivers), the replacement battery stopped working completely and the laptop would power off the second I disconnected the AC charger. There was nothing wrong with my original battery, it was just old and starting to fail as it would die quickly when not plugged in - and I ended up having to take this replacement back out and put the original battery back in! A waste of time and money. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F37Q5X9 | | Antenna Location | Laptop | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Brand | BatteryMon | | Compatible Devices | Laptop, Notebook | | Customer Reviews | 3.4 out of 5 stars 19 Reviews | | Manufacturer | Dongguan jiataiyuan electronics Co., Ltd | | Model Number | B31N1429 ,A1322 | | Recommended Uses For Product | Laptop | | Reusability | Rechargeable | | UPC | 713869877231 | | Voltage | 11.4 Volts | ## Images ![B31N1429 Laptop Battery Replacment for K501LB K501LX K501U K501UB K501UX K501UW K501LB5200 K501LB5200 K501LB5500 K501LX-NH52 Vivobook A501LX Notebook PC (11.4V 48Wh) - Image 1](https://m.media-amazon.com/images/I/71x1W-IBRBL.jpg) ![B31N1429 Laptop Battery Replacment for K501LB K501LX K501U K501UB K501UX K501UW K501LB5200 K501LB5200 K501LB5500 K501LX-NH52 Vivobook A501LX Notebook PC (11.4V 48Wh) - Image 2](https://m.media-amazon.com/images/I/61CIpSd9WSL.jpg) ![B31N1429 Laptop Battery Replacment for K501LB K501LX K501U K501UB K501UX K501UW K501LB5200 K501LB5200 K501LB5500 K501LX-NH52 Vivobook A501LX Notebook PC (11.4V 48Wh) - Image 3](https://m.media-amazon.com/images/I/61fRfLsXvhL.jpg) ![B31N1429 Laptop Battery Replacment for K501LB K501LX K501U K501UB K501UX K501UW K501LB5200 K501LB5200 K501LB5500 K501LX-NH52 Vivobook A501LX Notebook PC (11.4V 48Wh) - Image 4](https://m.media-amazon.com/images/I/618BQ667eBL.jpg) ![B31N1429 Laptop Battery Replacment for K501LB K501LX K501U K501UB K501UX K501UW K501LB5200 K501LB5200 K501LB5500 K501LX-NH52 Vivobook A501LX Notebook PC (11.4V 48Wh) - Image 5](https://m.media-amazon.com/images/I/61yGrNHVOqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent purchase - well worth it *by J***Z on June 5, 2019* This battery is awesome. It was a perfect fit and is giving me approx 10 hours of charge time. Its like it was when the computer was new. Also, Batterymon contacted me after I received the battery to offer any help I need and let me know I am covered under warranty - excellent purchase - well worth it. ### ⭐ Do NOT buy for Asus K501UW! *by T***Y on February 17, 2020* While the title and description claim it fits an Asus K501UW, it does not.

But the replacement is working as expected. The plug to connect the battery to the motherboard is slightly thicker than the original. It cannot be locked in place on my ASUS laptop. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/126738640-b31n1429-laptop-battery-replacment-for-k501lb-k501lx-k501u-k501ub-k501ux](https://www.desertcart.us/products/126738640-b31n1429-laptop-battery-replacment-for-k501lb-k501lx-k501u-k501ub-k501ux) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-23*
