BATTERY PANASONIC CF19 SERIES CF-VZSU48 CF-VZSU48U 6 CELL

(9/10)

As a replacement for the OEM battery this is a worthy alternative, it’s given excellent value for the money

Two years later and the battery is still working the way it should, better than the original battery did when it was the same age.

This was an exact replacement for the battery that died in my CF-19 Tough Book. It fit like it’s supposed to and powered up the laptop. Considering the older technology used in the machine, that eats batteries a lot faster than today’s processors, the amount of time it runs on one charge is pretty good and hasn’t really diminished after literally dozens of charge cycles. I have noticed some heating while charging but it’s hard to tell if this is 100% the battery heating up or if it includes and heat generated by the power distribution circuitry that’s responsible for charging the battery.

It’s hard to give you an indication of how long the battery lasts as of course it’s all dependant on what’s running and tasking it. I can say that the amount of time I get seems to be very similar to what the original battery offered when it was new.

It was a very good deal when I looked at the cost of a replacement from Panasonic, it quickly became a no brainier to buy this one even though aftermarket batteries sometimes aren’t good quality. I can assure you that the one I received is an excellent alternative.
