120V Battery Care and Maintenance


How long does it take the Oregon 120 Volt Professional Series batteries to charge?

BX975: from 0% to 100% capacity - approximately 300 minutes
BX650: from 0% to 100% capacity - approximately 180 minutes

How many times can I charge a battery before it is no longer usable?

Over time, all batteries will lose capacity based on usage and storage environments. The Oregon 120V Battery Duty-Life Indicator shows the available capacity of the battery.

Can I leave the battery hooked up to the charger? Will it cause damage if I leave it hooked up after it is charged?

Yes, the battery can remain hooked up to the charger. No, it will not be damaged if left hooked up.

Do batteries have to be completely discharged prior to charging them?

No, you can recharge the battery from any charge level. The lithium-ion battery technology used in the BX series of Oregon 120V Professional Series batteries does not reduce in available capacity if charged from any level above zero percent. The issue of “charge memory” is only applicable to older battery technologies.

How do I charge the battery on the road?

The C1600 charger for the 120 volt Professional Series batteries operates with any 110V/120V AC source that provides 400 watts of power or more. 

Can I use my car or solar panel to charge the battery?

The C1600 charger operates with any 110V/120V AC source that provides 400 watts of power or more. 

Can I overcharge a battery?

The BX series line of batteries that power the 120V Professional Series tools includes a Battery Monitoring System (BMS) that protects the battery from multiple internal and external hazards, including overcharge. The BMS automatically responds to the hazard by switching off the battery and displaying a corresponding error on the tool and battery.

How many chargers can I run on one AC outlet?

The Oregon C1600 charger is rated for 275W input power. National Electric Code analysis is likely to indicate no more than five C1600 chargers can be powered on a dedicated 15 Amp 120V AC circuit. Consult the national and your local code requirements for power that can be provided on your intended circuit. Take into account other appliances that may be on the same circuit as one circuit often powers numerous outlets. 

Can I repair my Oregon 120 Volt Professional Series battery?

In general, the 120 Volt Professional Series of batteries are not repairable due to safety concerns. However, specific items on the 120 volt series of batteries may be repairable including the black feet and fuel gauge label.  Please see a dealer for specific repair items for your battery model.

Will future products operate on the same battery platform/be backwards compatible with 120V Professional Series batteries?

Oregon is committed to continuing the expansion of the 120V product line using the BX series of batteries. Please visit for information about available product.

How does the cost of a battery compare to gas? Is this a savings or is it more expensive?

The answer depends on many variables; however, it is very common for users to experience a positive Return on Investment (ROI) when switching from gas to the Oregon 120V Professional Series. By investing in battery technology, you are buying your fuel up front and eliminating ongoing gas, fuel mix and much of the maintenance costs of traditional gas equipment. Please contact a sales representative for more information.

How is Oregon 120V Professional Series different from other commercial battery options?

The Oregon 120V Professional Series product line is the first line of battery powered outdoor power equipment that meets commercial crew performance requirements, including, high power, long runtime, and weather resistance, among many others. 

Oregon Professional Series tools are the first to achieve the Zero Emissions Equipment (ZEE) certification by the California Air Resources Board.

Is there a chance of electric shock?

Normal use of this tool is safe, even in wet conditions. Battery DC powered tools offer greater electrical protection than plug-in AC tools. Damage or modification to any electrical portion of the tool may cause risk of electrical shock. 
The charger is the only portion of this system that connects to traditional electrical outlets, so protect it from the weather. The charger is not serviceable.

What happens if it starts to rain? Can I store the battery in an open trailer?

Our products are UL rated and IP56 certified which means you can transport or operate them during inclement weather. The charger is an indoor-only charger.

How should I store my batteries?

When not in use, batteries should be stored in a cool, dry place. A high internal temperature may cause the tool to malfunction with the battery, so avoid storing it in direct sunlight. The design of the Oregon 120V Professional Series batteries allow for the use and transport in an outdoor environment, however, reducing exposure to the environment will allow the battery to last longer. Do not store for long periods in direct sunlight and/or rain.

How can I ship my battery?

As with all lithium-ion batteries, there are very specific requirements regarding shipping. The Oregon 120V Professional Series is considered high capacity and is subject to specific shipping regulations. Please check with your specific carrier before preparing any shipments, including ground and air.

What do I need to know about shipping lithium-ion batteries?

Special attention is required as local and national standards regulate the shipping of lithium-ion batteries. When transporting a damaged battery, box type and specific precautions and labeling requirements are important. Call Oregon at 1-800-223-5168, for more information.

What is the difference between State of Charge and Duty Life?

The battery is capable of communicating its State of Charge and Duty Life.
The State of Charge refers specifically to the percentage of energy remaining in the battery available for immediate use. A full State of Charge indicates the battery is at its full-charge capacity. An empty State of Charge indicates the battery needs to be charged.
The Duty Life refers to the approximate percentage of your battery capacity as compared to a new battery. All lithium-ion batteries reduce capacity due to time, use and charge cycles. Duty Life allows the user to estimate their battery’s available capacity as compared to a new pack.

What do I do with old batteries?

Oregon 120V Professional Series lithium-ion batteries (BX975 or BX650) can be recycled at Interstate Battery “All Battery Centers”

Why won’t my battery charge right away?

Firstly, confirm the charger is properly plugged into the wall and the battery-to-charger cable is accurately attached to the battery. If the battery is too warm to charge, the charger will indicate with a rapid blinking red light. You can leave the charger attached to the battery, and once the battery temperature reaches an acceptable level, the charger will begin charging the battery automatically. It is normal, especially on a warm day with heavy use, for a battery to become warm and exceed the acceptable charging temperature. Oregon 120V Professional Series batteries are engineered to monitor temperature when operating tools and when charging. When the battery is outside of its acceptable temperature range, it will delay the start of charging until the temperature returns to its normal range.

What causes a battery temperature to rise?

Higher ambient temperature, storage in direct sunlight, storage in a warm, enclosed trailer, and heavy use can all cause the battery temperature to rise.
