8-Cell 18650 Battery Pack

This pack contains eight KingSener INR18650-26E lithium-ion cells, each rated at 2600mAh and 3.6V. They are designed as direct replacements for worn laptop battery packs or custom EV power assemblies. The cells arrive new and match the original physical dimensions for straightforward installation.

Continuous 15A Discharge Limit

Each cell supports a 5C discharge rate, delivering up to 15A of continuous current. This ceiling defines the maximum sustained load the pack can handle without voltage sag or overheating. Builds that demand higher peak currents will exceed the safe operating area of these cells.

2600mAh Capacity and 1000-Cycle Life

The 2600mAh rating provides reliable runtime for typical laptop workloads and moderate EV applications. Cycle life is rated at 1000 full charge-discharge cycles before noticeable capacity fade. Users needing greater energy storage or longer calendar life will require higher-capacity cells.

Questions about this item

Should I buy the 8-cell pack or individual cells for my laptop repair?

The listing shows an 8-piece set of INR18650-26E cells; choose the full pack if your battery uses eight 18650 cells, otherwise order the exact count your pack requires.

What does the 2600 mAh rating mean for actual runtime in my laptop?

Each cell stores 2600 mAh at 3.6 V; total runtime scales with the number of cells in your pack and your laptop's power consumption.

The cell is rated at 5C and 15 A — what does that limit in practice?

The 5C rating means the cell can sustain a continuous 15 A discharge; your battery pack's protection circuit and laptop power draw will determine the actual current delivered.
