The Razer Blade Pro 17 (2017) is built for serious gaming and creative workloads with its large
17.3″ display and powerful hardware. But even the best laptop feels limited when the battery
starts to fail. Maybe your Blade Pro 17 shuts down the moment you unplug the charger, drains from
60% to 5% in minutes, or dies in the middle of a game or render. These are classic signs that the
original 99Wh Blade F1 battery is reaching the end of its life.

1. Common symptoms of a failing Razer Blade Pro 17 battery
High-performance 17.3″ gaming laptops draw a lot of power. Over time, the cells inside the 99Wh
battery degrade. Instead of failing overnight, your Blade Pro 17 usually shows a series of warning
signs first:
1.1 Fast drain, even during light use
-
Your Blade Pro 17 used to last several hours on web browsing or office work; now it struggles to
reach 1–2 hours on battery. - The battery percentage falls quickly once it goes below 50%.
- You lose a large chunk of charge just from streaming a short video or editing a document.
This usually means the real capacity is far below the original 99Wh. Windows still tries to
estimate runtime, but with worn-out cells those estimates are no longer accurate.
1.2 Sudden shutdowns on battery
- The laptop powers off abruptly when you start a game, 3D app or heavy multitasking on battery.
- Windows may still show 20–40% remaining before it shuts down.
- After restarting and plugging in, the reported battery percentage is much lower than before.
Under load, a weak cell can’t maintain stable voltage. The internal protection circuit cuts power
to prevent damage, resulting in a hard shutdown instead of a clean low-battery warning.
1.3 “Plugged in, not charging” or stuck charge level
- Windows reports “Plugged in, not charging” even though the adapter is working.
- The battery refuses to go above a fixed percentage (for example, 60–80%).
- The laptop works on AC, but runtime is very short or it turns off immediately when unplugged.
Sometimes these issues are caused by software or adapter faults, but if those are ruled out, it
often means the controller is restricting charge because the cells are heavily worn.
1.4 Extra heat and fans running more than before
- You notice the fans spinning up during light workloads where they used to stay relatively quiet.
- The underside of the chassis feels warmer, even when you’re just browsing or doing office work.
Aging lithium-ion cells can generate extra heat during charge and discharge. Combined with the
already powerful hardware in the Blade Pro 17, this can make the whole system run hotter, especially
if the battery is no longer healthy.
1.5 Swelling or physical distortion
- The touchpad feels slightly raised, uneven or harder to click.
- The bottom panel may show a subtle bulge or the laptop no longer sits flat on a desk.
Swelling is a critical safety warning. If the 99Wh Blade F1 pack starts to expand, it can put
pressure on the palm rest, keyboard and internal frame. In this situation, you should replace the
battery as soon as possible and avoid using the laptop on battery power.
1.6 Battery health warnings in reports or tools
- Battery diagnostics show “poor” or “very poor” battery health.
-
There is a large gap between Design Capacity and Full Charge Capacity in
Windows battery reports.
These warnings usually appear after the battery has already lost a significant portion of its
original capacity, matching the drain and shutdown symptoms you see in daily use.
2. How to confirm your battery is the problem
Before you invest in a new 99Wh Blade F1 replacement battery, it’s smart to confirm that the battery
itself—not the adapter or software configuration—is causing your Razer Blade Pro 17 issues.
2.1 Check the charger and basic power settings
- Use the original Razer power adapter or a high-quality, compatible charger.
- Inspect the plug, cable and DC jack for looseness, discoloration or visible damage.
-
Temporarily reset advanced power plans and battery saver modes back to default to rule out
misconfiguration.
If a known-good adapter doesn’t improve charging behavior or runtime, the battery is the more
likely culprit.
2.2 Generate a Windows battery report
On Windows 10/11:
- Open Command Prompt as Administrator.
- Type
powercfg /batteryreportand press Enter. - Open the generated HTML report from your user folder.
Compare Design Capacity and Full Charge Capacity. If the full
charge capacity is much lower than the original 99Wh, your battery has experienced heavy wear and
replacement is justified.
2.3 Use BIOS and any available Razer tools
- Enter BIOS/UEFI and check if any battery status or health warnings are shown.
- Use any Razer utilities that report battery condition, if available for your model.
Combined with real-world symptoms like fast drain, shutdowns or swelling, these checks give you a
clear picture of whether the Blade F1 pack has reached end of life.

4. Is it safe to keep using a weak or swollen battery?
Many users try to delay replacement by leaving the Blade Pro 17 plugged in most of the time. While
this can work for a while, it comes with several risks:
- Unexpected shutdowns can corrupt save files, project data or system updates.
-
Swelling or overheating can deform the chassis, damage the touchpad and stress
internal components. -
A severely degraded pack can place extra load on the charging circuitry and
potentially cause additional hardware issues.
If you notice swelling, cracks or abnormal heat around the battery area, stop relying on the
battery and plan a replacement as soon as possible.
5. Replacement options: DIY vs professional service
The Razer Blade Pro 17 (2017) is a large but densely packed laptop. Replacing the 99Wh Blade F1
battery is possible for experienced users but may be challenging if you are not comfortable opening
laptops.
5.1 Typical Blade Pro 17 battery replacement steps
- Power off the laptop completely and unplug the adapter.
- Remove the bottom screws and gently lift off the bottom panel.
- Disconnect the battery cable from the motherboard.
- Unscrew and carefully remove the old Blade F1 battery pack.
- Place the new 99Wh battery, secure it with screws and reconnect the cable.
- Reinstall the bottom cover, tighten all screws and test the laptop on battery power.
If these steps feel risky, the safest option is to purchase the correct replacement battery and
have a professional repair shop handle the installation.
5.2 Why choose a proper Blade F1 replacement
- Correct 11.4V operating voltage for the Blade Pro 17 power design.
- High 99Wh capacity to match the original design for a 17.3″ performance laptop.

Integrated protection against over-charge, over-discharge, short-circuit and abnormal
temperature. -
Backed by a 12-month warranty and 30-day return policy for
peace of mind.
6. How to care for your new Razer Blade Pro 17 battery
Once your new 99Wh Blade F1 battery is installed, a few simple habits will help you get the
maximum life from it:
-
Initial calibration: For the first few days, use the laptop on battery and let
it cycle between roughly 20% and 90% to help the controller and Windows learn the new capacity. -
Avoid extremes: It’s fine to hit 100% or 0% occasionally, but try not to leave
the battery fully charged or fully drained for long periods. -
Keep it cool: Use the laptop on a hard surface, keep vents clear and avoid
blocking airflow to reduce heat stress on the pack. -
Store smart: If you won’t use the Blade Pro 17 for a while, store it around
40–60% charge in a cool, dry place.
With a fresh 99Wh Blade F1 battery and good charging habits, your Razer Blade Pro 17 can once again
deliver the performance and portability you bought it for—whether that’s gaming on the go, editing
content away from your desk, or simply enjoying smooth everyday use on battery power.
