Quick answer
The Lenovo ThinkPad E480 and E580 share the same battery form factor and connector, so a replacement battery designed for one will physically fit the other. The key difference is capacity and voltage, which affects runtime and compatibility with power management.
Battery compatibility across the E-series
The ThinkPad E480 (14-inch) and E580 (15-inch) use the same battery connector and mounting points. This means a replacement battery listed for the E480 will also fit the E580, and vice versa. The same applies to the E490, E590, R480, and R580 models, which share the same internal battery design.
However, not all batteries are identical. The original Lenovo batteries for these models come in different capacities and voltages. A higher capacity battery (e.g., 4100mAh) will provide longer runtime but may require a slightly different charging profile. Always check the voltage rating (11.4V is standard) to ensure compatibility with your laptop's power management system.
Trade-off: Capacity vs. fit
While the physical fit is the same, the battery capacity affects how long your laptop runs on a charge. A 4100mAh battery offers more runtime than a lower-capacity alternative, but it may be slightly thicker or heavier. In practice, most aftermarket replacements are designed to fit within the same chassis, so the difference is minimal.
The trade-off is that a higher capacity battery may not be recognized by older BIOS versions or may charge slightly slower. For most users, this is not an issue, but if you rely on precise power management, stick with a battery that matches the original voltage and capacity range.
Trade-offs at a glance
- Fit guarantee: The E480, E580, E490, E590, R480, and R580 all use the same battery connector and mounting. A battery listed for one will physically fit the others. Check your laptop model number before ordering.
- Capacity choice: Higher capacity (e.g., 4100mAh) gives longer runtime but may be slightly thicker or heavier. Standard capacity (e.g., 3000mAh) is lighter and may charge faster. Choose capacity based on your need for portability vs. runtime.
- Voltage consistency: Most replacements use 11.4V, which matches the original. Using a different voltage can cause charging issues or damage. Always verify the voltage rating. Stick with 11.4V for guaranteed compatibility.
