Panasonic CF-18 ToughBook Replacement Battery CF-VZSU30U

This is a brand new Panasonic ToughBook CF-VZSU30U battery replacement. The superior quality cells inside this battery pack from South Korea provide longer service life and longer run times. There are two key components inside your battery pack to look for when buying a new computer battery. The quality of the battery’s lithium-ion cells and the quality of the computer chip set in the battery pack. This battery is built with the best components, not the cheapest.
This battery is rated at 6600 mAh or 50 Whr. You can expect 5-6 hours of run time with this battery.
The other key component inside the battery pack is the computer chip set that contains the program interface with your laptop’s battery meter software and important safety features that monitors when to charge and stop charging your battery. We use Texas Instruments top notch components for this.
When choosing a laptop battery, cheaper is not better. Cheaper batteries use inferior Chinese cells that typically wear out in just 3 to 6 months. The main indicators of inferior Chinese cells are the low price of the battery and a lower mAh rating. Inferior batteries also use inferior computer chip sets inside that can lead to compatibility issues with your laptop. Although every brand of laptop battery is hand assembled in China, the key to getting a great battery is knowing what components are inside.

How to care for your Panasonic ToughBook CF-VZSU30U battery.

You can extend the life of your CF-VZSU30U laptop battery significantly through the proper care and handling of your battery.

• Any new laptop battery should first be fully charged by leaving it plugged in overnight. Once a computer battery is fully charged it will no longer accept any more power. It is a common practice to leave laptops plugged in after they have been turned off so that the battery has a full charge the next time you use your laptop. It is probably fully charged within 5 hours.
• A brand new notebook battery is in a weakened condition since it has not been conditioned yet. Condition and break in your new battery by performing 5 partial discharge and recharge cycles the first week you receive your new battery.
• Run on battery power without the AC adapter cord at least once a week to keep the battery cells active and at their peak potential. When your laptop is plugged into the power adapter the battery goes to "standby mode" while your laptop runs directly on electricity from the wall outlet.
• Even though your battery indicates it is fully charged, your battery will return to a weakened state again in a few months if it does not get some exercise through partial discharge and recharge cycles while running on battery power alone.
• If your battery has not been actively used 2 months or more, condition your battery again with 3-4 partial discharge & recharge cycles to increase the batteries capacity and run time.
• Don't run your battery all the way to empty. Your battery will have a longer service life if it receives shallow discharge and recharge cycles. Research has shown that the useful life of the battery will be much longer if you begin to recharge the battery any time before reaching 20% of the remaining power capacity. Recharging the battery even after 10 minutes will not reduce the battery's life span as lithium batteries do not have the memory effect which was found in older NiCad battery technology. NiCad batteries have never been used in laptops, even the earliest models.
• Never run your battery below the 3% critically low warning point. If your battery is run below this point it may not have enough energy to recharge. This may effectively "kill" your battery.

How can I extend my Panasonic ToughBook CF-VZSU30U battery run time?

You can extend your battery run time by minimizing the power drain on your battery. A CF-VZSU30U battery will run approximately 5 to 7 hours when the battery is new. Even longer times can be achieved by minimizing the power consumption of your laptop. Here are the top ways to reduce your power consumption.

• Reduce the brightness of your laptop screen. This is the main drain on your Panasonic CF-VZSU30U battery by far.
• Avoid using the CD or DVD drive as the motor consumes a fair amount of power.
• Turn off your wireless finder if you are not using the internet.
• Remove any devices plugged into your USB ports or other ports.
• Close out programs you are not using. By minimizing the load on your CPU, sometimes you can avoid having the cooling fan turn to its high speed mode.
• Increase your memory to at least 4 Gigabytes. This creates less work for your hard drive. Data is temporarily written to your hard drive when your memory is not sufficient to hold all the data on the many pages you may be accessing.
