With a 90Wh capacity and a 15.4-volt design, this battery is engineered to maximize runtime while keeping size and weight in check, making it an ideal upgrade for busy professionals who demand peak performance from their mobile workstation. Built to mirror the exact form and function of the original components, it restores your ZBook to its factory power profile without compromising safety or compatibility. Whether you’re on a design sprint, in a client meeting, or editing on-location, this battery is crafted to support your workflow with consistent, long-lasting energy.

  • High-capacity, 90Wh Li‑Ion battery built to power demanding workloads on ZBook 15 G5 and ZBook 15 G6 laptops. This battery is engineered to deliver extended runtimes between charges, enabling longer sessions of 3D modeling, CAD, video editing, and data analysis without constant recharging interruptions. The optimized energy density helps you stay productive during travel or in spaces where wall outlets are scarce, so you can focus on your work rather than on finding a power source.
  • Exact OEM compatibility and part-number alignment for a seamless replacement. The VX04XL-BTI is designed to correspond to OEM references HSTNN-IB8F, VX04090XL-PL, L05766-850, VX04XL, L05766-855, and L06302-1C1, ensuring proper connector fit, latch alignment, and electrical interaction with your ZBook’s charging system.

  • Safety-first engineering meets real-world durability. The cell chemistry and internal protection circuitry are selected to minimize degradation under typical operating conditions, with an emphasis on thermal stability and consistent performance. This translates into steadier charging behavior, less heat buildup during heavy workloads, and more predictable performance across a wide range of temperatures, so you can rely on this battery in different climates and work settings.
  • Effortless installation and restored performance. The VX04XL-BTI is designed as a straightforward replacement that mirrors the original battery’s dimensions, connectors, and mounting points. With the correct latch engagement and connector alignment, you can swap in a few careful steps and return your ZBook to its full power quickly, enabling you to resume work without prolonged downtime or complex setup procedures. A properly seated battery also reduces the risk of intermittent power loss during critical tasks.

how to install BTI VX04XL-BTI 15.4V 90Wh Li-Ion Battery

To install this replacement battery safely and effectively, begin with a powered-down laptop and a disconnected power source. Place the ZBook on a clean, static-free surface and flip it over to access the battery bay. Gently release the existing battery latch and remove the old unit, taking care not to pull on any connectors. Align the VX04XL-BTI so that the connector pins match the motherboard interface and the battery fits snugly into the bay. Slide the battery into place until it sits firmly and the latch clicks into the locked position. Reconnect any cables you previously detached, reassemble the back panel, and connect the charger to verify proper charging behavior. Power on the device and allow the battery to calibrate by charging to full, then discharging to a low level before charging again. For best results, perform a couple of complete charge-discharge cycles to establish an accurate gauge of your new battery’s capacity. Store and operate the notebook within normal temperature ranges to preserve longevity and performance.

Safety tip: handle the battery by the edges, avoid puncturing the cells, and never attempt to bend, crush, or puncture the pack. If you notice unusual heat, swelling, or a drastic drop in performance, discontinue use and seek professional guidance. Proper disposal of old batteries is essential—follow local recycling guidelines to minimize environmental impact.

I’m really happy with these screen protectors overall. The glass feels high quality and provides good protection without affecting the clarity or touch sensitivity of the iPad screen. The installation process was straightforward, and I didn’t have issues with bubbles as long as I followed the instructions carefully. Once applied, it looks clean and fits the screen well. Overall, this is a reliable and simple way to protect your iPad screen while keeping everything looking clear and responsive.

Super great screen protectors, but bad prep materials.
Model: iPad A16 11th 2025 /10th 2022, Model: iPad A16 11th 2025 /10th 2022
I got an iPad A16 for my birthday and wanted some affordable but durable screen protectors. These are great, but there were a few problems I had. Pros: These fit perfectly, don't shatter or chip easily, and are a very good price. Cons: The dust absorber stickers that come with the kit aren't even close to sticky enough (I had to use just normal stickers, which was fine). The alcohol prep pad was pretty dry too (I had to use a different alcohol wipe). The screen protectors themselves are amazing. You can trust them to keep your iPad safe. Just be prepared to DIY the prep a bit. I would still reorder and recommend these!
