Replacement Battery for Toughbook CF-30 CF-31 CF-53

This lithium-ion pack replaces original part numbers CF-VZSU46, CF-VZSU46AU, CF-VZSU46U, CF-VZSU46S, CF-VZSU46R, CF-VZSU71U, CF-VZSU72U and CF-VZSU1430U. It fits Panasonic Toughbook CF-30, CF-31 and CF-53 series laptops. The unit is supplied new with a built-in circuit protection board for safe operation.

87 Wh capacity and 500-plus recharge cycles

The battery delivers 8.55 Ah at 10.65 V for a total of 87 Wh. Rated for more than 500 recharge cycles, it supports extended field use between charges. For the first installation, discharge to five percent, charge to ninety-five percent and repeat three to four times to calibrate the cells. Buyers needing longer runtime than 87 Wh provides should consider higher-capacity alternatives if available for their model.

Factory-built safety protections

Produced under factory control, each pack includes short-circuit, overheat and overload protection. The form factor matches the original bay exactly, so no adapters or case modifications are required. Users who need hot-swap capability or a secondary battery bay will find this single-pack design does not support those configurations.
