Batteria Dell 51 Wh 3 celle Li-Ion ricambio per laptop Dell (MPN 5MVGP)

Rechargeable 51Wh 3-cell Li-ion battery designed as a replacement for compatible Dell laptops. This direct-fit internal battery provides portable power to restore or extend run time for systems originally equipped with a similar 3-cell module. The battery is intended for use where the original battery exhibits reduced capacity, excessive self-discharge, or fails to hold a charge, and is manufactured to match the physical and electrical fit of supported Dell models.

Advantages

The 51Wh Li‑ion chemistry delivers a balance between capacity and weight, supporting typical productivity tasks without significantly increasing device mass. As a form-fit replacement, it simplifies installation with the same connector type and voltage range as the original Dell internal batteries it is matched to. Built-in protection circuitry helps prevent overcharge, overdischarge and short circuits, contributing to safer operation when installed correctly.

Suitable for

• Replacing a degraded internal battery in supported Dell laptop models
• Extending mobile working hours for office tasks, browsing and media playback
• On-site maintenance and laptop repair services requiring a direct-fit rechargeable module
• Users who need a lightweight replacement battery with moderate capacity

Key specifications

• Capacity: 51 Wh (watt-hours)
• Cell count: 3-cell lithium-ion configuration
• Chemistry: Li‑ion (lithium-ion)
• Typical use: internal laptop battery, rechargeable
• Protection: integrated battery management circuitry for charge/discharge and short-circuit protection
• Physical type: slim internal module designed to match form factor of compatible Dell systems

How to use

Power down the laptop, disconnect external power and remove the service access cover or bottom panel according to the laptop manufacturer’s instructions. Disconnect the original battery connector from the motherboard, remove any retaining screws or brackets, and lift out the old module. Place the replacement 51Wh battery in the bay, secure it with the original fasteners, and reconnect the battery connector. Replace the cover and reconnect external power to perform an initial calibration by charging to full capacity and allowing one full discharge/charge cycle if recommended by the laptop documentation.

Recommendations

Use the replacement battery only in compatible Dell laptop models and follow manufacturer service instructions. Store unused batteries at partial charge in a cool, dry environment and avoid exposure to temperatures outside the laptop maker’s specified range. Dispose of depleted batteries through approved recycling channels and avoid mechanical damage or exposure to liquids.
