9-Cell Li-Ion replacement for Toughbook

This 10.8V 7800mAh battery replaces OEM part numbers CF-VZSU29A, CF-VZSU29ASU, CF-VZSU29AU, CF-VZSU29U and CF-VZSU29. It fits Panasonic Toughbook 29, 51 and 52 models including CF-29, CF-51 and CF-52. The pack is built with nine lithium-ion cells and rated at 84Whr. It is sold new and ready to install.

Runtime limited by cell chemistry and capacity

The 7800mAh rating sets the total charge the pack can deliver at 10.8V. Actual run time depends on the notebook power draw, screen brightness, wireless activity and temperature. Lithium-ion cells lose capacity gradually over charge cycles, so runtime will shorten as the battery ages. No circuitry in the pack can extend the basic energy limit.

Upgrade from lower-capacity 6-cell packs

Many original Toughbook batteries used six cells with less capacity. Moving to this nine-cell 7800mAh unit adds stored energy without changing voltage. The jump is worthwhile when field work demands longer untethered operation and the slightly larger pack fits the battery bay. It does not help if the system charging circuit or BIOS limits charge current.
