54Wh DR02P R73TC Laptop Battery Compatible with Dell Latitude 5550 5540 5450 5440 Precision 3590 3580 3480 3490
Quick take
This 54Wh Li-ion replacement battery (DR02P, 11.4V, 4623mAh) is built for several Dell Latitude 5000-series and Dell Precision 3000-series laptops. The most consistent buyer themes are easy installation and reliable “works like a new battery” performance. The main caveat is fit and compatibility, so verify your original battery’s model and shape, especially the connector location.
Pros and cons
Pros
- Designed as a direct replacement for specific Dell Latitude and Precision laptop models.
- 54Wh (4623mAh) capacity with 11.4V Li-ion battery specs.
- Many buyers report straightforward installation and full functionality after swapping.
- Positive value perception compared with replacing parts through other routes.

What buyers think
Buyer-review evidence is mostly consistent around usability and outcome. Reviews commonly mention that installation is straightforward once the old pack is removed, and that the replacement powers and charges normally. Several shoppers also describe strong real-world endurance compared to older batteries, and at least a few call out a snug or slightly tighter fit versus the factory pack. Overall, the pattern suggests this battery is a practical upgrade path when you have the correct Dell-compatible battery model.
Note on evidence: Review themes are limited to the snippets provided, so buyer sentiment about long-term health (months or years) is not fully established here.
Who this battery is for
This battery is a good match if you need a replacement for a compatible Dell Latitude 5550/5540/5450/5440 series laptop or a Dell Precision 3490/3480/3580/3590 series laptop, and your current battery part number/model aligns with DR02P / R73TC-compatible configurations.
It is also a solid option if you want a capacity-focused replacement (54Wh) rather than downsizing, and you are comfortable doing a battery swap yourself.
Key compatibility details to verify before you buy
- Battery model and part numbers: Look for DR02P (also listed alongside compatible identifiers such as R73TC and 2X1V9 / 0803W6 / 02X1V9, and 803W6 / 02X1V9 depending on the configuration).
- Electrical specs: Voltage is 11.4V, and capacity is 54Wh (4623mAh), Li-ion (3-cell).
- Physical fit: Confirm the battery shape and connector location. A wrong pack may not seat properly or may not connect correctly.
- Before installing: Compare the replacement to your existing battery appearance, including cable length and connector type (short vs long), so you do not end up with a mismatched connector.
Installation experience and everyday performance
Buyers report that installation is generally simple once the old battery is removed, with the replacement functioning normally afterward. In addition to “it works,” some reviews mention longer-lasting runtime compared to their original failing battery. One recurring nuance is that the battery can be slightly tighter in the bay, but it still seats and works for those shoppers.
If your laptop does not recognize the battery immediately, the troubleshooting approach typically involves reseating the battery more than once and power-resetting the laptop without the AC adapter, then retrying. (If you are not comfortable with this, a repair technician can help prevent connector stress.)
Pros and cons (real-world tradeoffs)
Pros: This is built around specific Dell Latitude and Precision model compatibility, it matches the listed 11.4V and 54Wh class, and buyer feedback highlights functional reliability after installation.
Cons: The most important risk is choosing the wrong battery variant. Fit can be slightly tighter than stock, which is not necessarily a dealbreaker, but it reinforces the need to verify your existing battery’s model, shape, and connector details first.
Is it worth it?
If you have one of the supported Dell Latitude 5000-series or Dell Precision 3000-series laptops and you can confirm your current battery is the DR02P/R73TC-compatible type, this replacement is a straightforward way to restore everyday portability. It tends to earn confidence from buyers who want a functioning battery without complicated setup, but you should only proceed once you verify compatibility by model and connector shape.
