Questions about this item

How many charge cycles will the Li-polymer cells last before capacity drops?

OEM-grade Li-polymer cells are engineered for long cycle life and stable performance across daily charge cycles.

What limits runtime first during a full workday on the 25.4Wh pack?

The 2200 mAh capacity at 11.55V sets the total energy available, so runtime ends when that 25.4Wh is depleted.

Does the 11.55V battery run hot or draw more power under continuous load?

Built-in protection guards against overheating, over-charging, over-discharging and short-circuit conditions during extended use.
