Replacement laptop battery PATONA PT2829, Li‑Ion 11.1V with 6600mAh capacity, designed for compatibility with multiple Dell Inspiron and Latitude models (e.g., Inspiron 4420, 4520, 4720, 5420/5425, 5520/5525, 5720, 7420, 7520, 7720 and 14R series). Provides portable power for system mobility, spare-part replacement, and extended runtime for everyday use, office work and travel.

## Long description

PATONA 2829 is a replacement 9‑cell laptop battery designed for a range of Dell Inspiron, Latitude and Vostro models. It provides a Li‑Ion power source with nominal voltage suitable for older Dell notebooks that accept 11.1 V battery packs. The battery is supplied as a single unit in black with yellow accents and is intended as a spare or replacement part for compatible systems.
Advantages
The battery offers a high‑capacity 9‑cell configuration that extends run time compared with lower‑cell packs and uses lithium‑ion chemistry for a balance of energy density and weight. It is built as a direct replacement for original batteries in supported Dell models, allowing straightforward swap‑in installation without modifications.
Suitable for
Replacing a worn or failed battery in compatible Dell Latitude E6420 / E6430 / E6520 / E6530 and related Latitude series notebooks
Servicing Inspiron models listed by the manufacturer that accept the same battery form factor
Providing a spare battery for users who need extended unplugged runtime for older Dell laptops
When it may not be suitable
This battery is intended for the specific Dell models that use the same 9‑cell 11.1 V lithium‑ion pack. It will not fit or function in Dell laptops that require different voltages, cell counts, or a proprietary connector. It is not intended for modern Dell models that use newer battery designs or internal batteries soldered into the chassis.
Key specifications
Cell configuration: 9 cells
Chemistry: Lithium‑ion (Li‑Ion)
Nominal voltage: 11.1 V
Capacity: approximately 6600 mAh (typical for this type)
Colour: black with yellow accents
Quantity: 1 piece
How to use
Power down the laptop, disconnect the AC adapter, and remove any locking mechanisms or release latches that secure the existing battery. Slide out the original battery and insert the PATONA 2829 pack until it clicks into place. Reconnect the AC adapter and power on the laptop to verify charging and proper battery detection. Follow standard battery care: charge fully before first use and avoid exposing the battery to excessive heat or moisture.
What to consider before purchase
Confirm your laptop model appears among the supported Dell Inspiron, Latitude or Vostro series that accept a 9‑cell 11.1 V pack
Check the physical shape and connector location of your current battery to ensure mechanical compatibility
Verify that your system requires a removable external battery rather than an internal or proprietary type
Usage recommendations
For best results, calibrate the battery by charging it fully, then discharging to around 5–10% and recharging once a month. Store the battery at roughly 40–60% charge if it will not be used for extended periods, and avoid prolonged exposure to temperatures above 45°C.
