Why Choose HTJ 93FTF Battery?

• Workstation-Grade Stability:
  The Precision 3520 is a power-hungry workstation. HTJ’s 93FTF is engineered to handle the high-current draw of i7 processors and discrete Quadro graphics, ensuring no system throttling or random shutdowns during rendering or heavy multitasking.
• 4V High-Density Power:
  We use premium Lithium-polymer cells that maintain a flat 11.4V discharge curve. This ensures your Latitude or Precision stays at full clock speed for longer, even when the battery percentage drops below 30%.
• Heat-Shielded Polymer Construction:
  Internal workstation batteries are located near high-heat components. HTJ uses thermal-stable casing materials to prevent the “Battery Swelling” that can lead to trackpad failure or chassis warping in the Latitude 5490/5580 series.
• Full SMBus Integration:
  Our 93FTF chipset is programmed with the latest Dell Power Management handshake. This provides 100% accuracy for BIOS health checks, Windows “Time Remaining” estimates, and full support for Dell ExpressCharge technology.

How to Install Your New 93FTF Battery？

The Dell 93FTF is an internal battery. A Phillips #00 screwdriver is required for installation.

⚠️ Pre-Installation Safety Check:

• Static Safety: Discharge your body’s static electricity by touching a metal surface.
• Power Off: Ensure the laptop is completely shut down, and the charger is unplugged.

93FTF Battery Step-by-Step Installation Guide:

1. Open Chassis: Unscrew the screws on the bottom panel of your Latitude or Precision.
2. Cable Removal: Carefully unplug the battery connector from the motherboard. Do not pull on the wires.
3. Unscrew Battery: Remove the screws securing the 51Wh battery to the laptop frame.
4. Install HTJ 93FTF: Place the new battery into the bay and tighten the securing screws.
5. Reconnect: Firmly plug the battery cable into the motherboard slot.
6. Close & Sync: Reattach the bottom cover. Plug in your AC adapter and charge to 100% before your first mobile session.

💡 Pro Tip (Optimizing Lifespan):

To maximize the life of your 51Wh battery:

1. Avoid keeping the laptop at 100% charge 24/7 if using it as a desktop replacement.
2. Use the Dell Power Manager app to set a custom charging limit (e.g., stop charging at 80%) to significantly extend the lifespan of the cell chemistry.

FAQ (Frequently Asked Questions)

Q: Is 93FTF the same as GJKNX?
A: They fit the same laptops, but 93FTF is 51Wh (3-cell), and GJKNX is 68Wh (4-cell). The GJKNX is physically longer. If your laptop has space, the 68Wh is an upgrade, but the 93FTF is the direct replacement for standard mid-tier builds.

Q: Will this fit if I have a 2.5″ Hard Drive?
A: Yes. The 51Wh 93FTF and 42Wh D4CMT are both “short” enough to accommodate a 2.5″ SATA drive bay in the Latitude 5480/5490 series.

Q: My battery says 11.4V, but yours is 11.1V. Is that okay?
A: Yes. 11.1V and 11.4V are nominal ratings for 3-cell polymer batteries and are 100% cross-compatible in these Dell models.

Q: My current battery is a GJKNX (68Wh). Can I use this 93FTF (51Wh)? A: Yes, it is physically shorter, so it will fit perfectly in the screw mounts. You would use the 93FTF if you are adding a 2.5″ SATA hard drive to your Precision 3520, as the 68Wh GJKNX is too long to allow for a second drive.

Q: Is the 93FTF better than the 42Wh D4CMT? A: Yes. The 93FTF provides about 20% more runtime (51Wh vs 42Wh) while occupying nearly the same footprint. It is the ideal “balanced” upgrade for Latitude 5490 users who want more power without moving to the bulky 4-cell version.

Q: Why does my Precision 3520 get so hot near the battery? A: The 3520 is a workstation with high-performance graphics. The HTJ 93FTF is built with heat-resistant internal separators to ensure that the warmth from the CPU/GPU doesn’t cause the battery cells to degrade or swell over time.

Q: Do I need a different cable for the 93FTF? A: No. The 51Wh 93FTF, 42Wh D4CMT, and 68Wh GJKNX all use the same 8-pin battery connector cable. You can reuse your original Latitude/Precision cable.

Laptop Maintenance Tips:

1. New battery: For using a new battery, you’d better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely
2. Overuse: Do not always run a battery to 0%, as this would shorten its usage life.
3. Charging sequence: When charging, first install the battery, then turn on the power. When fully charged, first cut off the power, then pull the power plug.
4. Long-term storage: Please store the unused battery fully charged. (Charge it once a month.) Do not store at low power to prevent reducing the lifespan of a battery
5. Charger: Do not replace the laptop adapter casually. If the original adapter cannot be applied due to malfunction or damage, please replace the models so as not to reduce the service life of the battery due to incompatibility.
