6-Cell Battery Pack for previous model FZ-54 (replacement battery)

Jaltest 6-Cell Battery Pack for Panasonic CF-54 Rugged PC (SKU 29535)

If your shop runs Jaltest diagnostics on the previous-generation Panasonic Toughbook CF-54 rugged laptop, this is the genuine OEM replacement battery that keeps it in service. Part number 29535 is the 6-cell lithium-ion battery pack designed specifically for the CF-54 platform — not a generic aftermarket cell, but the exact Cojali/Jaltest-authorized replacement for your existing rugged PC. When your CF-54 battery degrades to the point where you cannot get through a full day of truck diagnostics without hunting for an outlet, this is the part to order.

What This Battery Fits

This battery fits the Panasonic Toughbook CF-54, which was the previous-model Jaltest Rugged PC before the current FZ-55 platform. If you bought your Jaltest system a few years back and it shipped with a CF-54 laptop, this is your replacement. The current FZ-55 uses a different battery (part number 70100006). These are not interchangeable — order by your laptop model, not just cell count.

Why Replace Instead of Upgrading?

Your CF-54 still runs Jaltest software perfectly well. The platform is proven, your technicians know it, and replacing a worn battery costs significantly less than buying a new Jaltest Rugged PC. A fresh 6-cell pack restores full-day runtime so you can diagnose Class 8 trucks, buses, and trailers in the field without being tethered to shore power.
