Get improved laptop performance and longer battery life with a new Panasonic CF-17 ToughBook CF-VZSU15 replacement battery.

We use premium Panasonic brand battery technology that provides longer run times between charges as well as a longer service life than cheaper, lower quality batteries.

Li-ion batteries are not subject to the memory effect common with older battery technology like Ni-Cad. This means you can recharge your laptop any time without diminishing your battery capacity.

All our Panasonic ToughBook batteries are tested and inspected before shipment and are backed by a 1 year warranty and 30 day guarantee.

You can expect about 2 hours to 3-1/2 hours of run time with this computer battery when new, depending on your energy use. This battery replaces the Panasonic ToughBook CF-17, CF-34, CF-M34, CF-M34J, CF-M34N, CF-M34R, CF-M34T series.
