The battery ships as a standalone replacement requiring no additional cables, tools or software. Physical dimensions and connector layout follow the factory design so the swap is completed inside the chassis. A twelve-month warranty covers the unit from the date of purchase.

Verify your exact model

Confirm the laptop model suffix (for example 83FR, 83A0 or 83CC) and cross-reference the OEM number printed on your old battery. This pack does not fit other Lenovo series or older generations. Buyers needing a higher-capacity pack or a different voltage should look elsewhere.

Questions about this item

When will the 2-cell 4947mAh lithium-ion pack need replacement?

A 2-cell lithium-ion pack generally keeps most of its capacity for two to three years of daily charging; runtime will gradually shorten until a new battery is required.

What limits runtime first during continuous use on the 7.68V 4947mAh battery?

The 4947mAh capacity sets the total energy available, so sustained workloads drain the pack until it reaches the low-voltage cutoff and the laptop shuts down.

How much heat or noise does the 5B11B36278 produce when the laptop runs all day?

The battery itself is silent and generates only modest warmth during discharge; any fan noise or extra heat comes from the laptop's own cooling system, not the pack.
