Extended battery life

14 Jul 2009

The battery life of the Field PC is dependent upon the application (environmental conditions, type of work being performed, etc.) in which the Field PC is being used and the number of accessory devices being powered by the Field PC. Even though a standard rechargeable battery pack for the Field PC can last for a full work day (8-10 hours) in most applications, battery life can range from 4 hours up to 16 hours depending on your application and accessory devices.

 

Certain accessories and functions can drastically increase the power consumption of the Field PC, such as the following:

 

 

 

Reducing the number of accessories and functions being used simultaneously, or setting up such accessories and functions to be disabled or minimize power usage automatically when not in use will increase battery life. You can adjust timers in the operating system settings (control panel) to automatically turn off backlights, stop communications, or even suspend (turn off) the unit after a short period of inactivity. For more information on power supplied by the Field PC to accessory devices, please visit our "Power Devices through Ports or Card Slots" FAQ website.

If you need more battery life from the Field PC than what the current rechargeable battery pack provides for your application, and you do not want to decrease the number of accessories and functions being used simultaneously, below are some recommendations.

 

Note: In the Allegro Field PC, make sure you are using a battery pack that was purchased through Juniper Systems or an authorized product reseller. We can not warrant how well a battery pack purchased through a third-party will function in the Field PC. For more information, please visit our "Where to buy Allegro Field PC batteries" FAQ website.

Refresh Battery or Purchase a New Battery

 

If the battery life of your rechargeable battery has only recently started to diminish, please visit our "Battery life less than when new" FAQ website.

If the Field PC battery pack does not seem to charge to full capacity initially or after it has been operated in cold temperatures, please visit our "Battery pack will not charge to full" FAQ website.

Extra Rechargeable Batteries

 

It is a good idea to carry extra rechargeable battery packs that have been previously charged to full capacity. The batteries of the Field PC are "warm-swappable", meaning that you can swap a depleted battery with another fully charged one within 5 minutes without losing your place on the Field PC.

 

If you are using the AA alkaline battery holder for the Allegro Field PC, you can carry extra AA alkaline batteries to swap when in when necessary (though this accessory item may limit some functionality of the Field PC).

 

External Battery Charger

 

You can purchase an external battery charger to charge an extra battery pack outside of the Field PC while the original battery is being charged in the Field PC. These external battery chargers can also be used in vehicles. Please contact Juniper Systems or aproduct reseller to purchase this accessory.

Vehicle Charger

 

If you are unable to swap out the battery for a new one, or would prefer to not carry extra battery packs, you can charge the Field PC between uses while remaining in the field using a vehicle (cigarette lighter) charger. The external battery charger can also be used in a vehicle to charge Field PC battery packs directly.

 

Third-Party or Custom Power Supply

 

Caution: It is possible to use some third-party or custom power supplies, such as connecting directly to a vehicle battery (12V lead-acid), solar panel, or generator (crank, pedal, etc.) to provide addition power to the Field PC, but you do so at your own risk.
