Quick take
This 68Wh GJKNX replacement battery is built to fit select Dell Latitude and Precision 15 models that require a 7.6V Lithium Polymer pack.

The main thing to confirm is exact model and compatibility before you buy.
Pros and cons
Pros
- 68Wh capacity replacement option (helpful when your original battery no longer lasts).
- Compatible with a defined list of Dell Latitude and Precision 15 models, including Latitude 5490/5480/5580/5590 and Precision 15 3520/3530 series.
- Safety-focused protection features (overcharge, overdischarge, over-temperature, short-circuit).
- Easy install reported by buyers, with the battery working and charging as expected.
Cons
- Compatibility depends on your exact Dell model and battery requirements, so double-check before ordering.
What buyers think
Buyer-review evidence is limited, but the available feedback centers on a few decision-relevant themes. Most comments focus on installation being easy and the battery working as expected after replacement, including charging and normal day-to-day use. A smaller amount of feedback suggests runtime can drop under heavy workloads, such as gaming, which is a common reality for many laptop batteries regardless of brand. Overall, buyer sentiment appears most positive around fit, straightforward replacement, and baseline charging performance, with limited evidence about long-term endurance across many usage types.
Who this battery is for
This replacement is a practical choice if you have a compatible Dell laptop whose original battery is no longer keeping charge. The 68Wh capacity and 7.6V Lithium Polymer design make it aimed at restoring usable unplugged time, rather than being a “small capacity” workaround.
Compatibility checklist before you buy
Battery compatibility is the make-or-break factor. Use the model list and key requirements to confirm you are matching the right unit. This battery is intended for various Dell Latitude models such as 5490, 5480, 5580, 5590, and also several E-series Latitude configurations, plus Dell Precision 15 3520/3530 series. It is labeled as a 7.6V battery and uses the GJKNX model number.
Before ordering, verify: your exact Dell model number (not just the series), the battery voltage requirement (7.6V), and that your laptop uses the GJKNX-style replacement.
Performance and real-world expectations
From a buyer standpoint, the most consistent theme is that the battery functions correctly once installed, including charging. In everyday mixed use, a replacement battery is primarily judged by whether the laptop powers on normally, charges without issues, and delivers reasonable runtime for typical tasks.
For heavier loads, such as gaming, expect shorter runtime. That does not automatically mean the battery is defective, but it is a helpful expectation-set for people buying primarily for high-performance, unplugged gaming.
Safety and reliability features
This battery includes multiple protection features designed to reduce common risks associated with lithium packs, including overcharge, overdischarge, over-temperature, and short-circuit protection. While no battery is “set and forget,” these safeguards are a relevant buy consideration when selecting a replacement for an older laptop.
Pros and cons recap
- Buy this if: you want a 68Wh replacement option for a compatible Dell Latitude/Precision 15 model, and you care most about restoring charging function and improving unplugged time.
- Avoid or double-check if: you are unsure your laptop battery is actually 7.6V or you cannot confirm the GJKNX match for your specific model.
- Use-case note: if your priority is long unplugged gaming, consider that demanding workloads can drain most laptop batteries quickly.
