How long does it take to charge the 40-B140 battery with the 40-C80 Charger?

It takes 2 hours and 40 minutes to charge the included 40-B140 battery with the included 40-C80 Charger.

Does the 125i Power Axe require a special chainsaw oil?

No, the 125i uses standard Bar and Chain Oil, just like a gas saw.

How much wood can I cut on a single charge with the 125i?

When using a new, fully-charged Husqvarna 4 Ah battery on normal mode, the 125i can typically handle 255 cuts on a 4x4* before battery is depleted. For larger residential tasks like felling a small tree and bucking it into firewood, one battery charge is usually sufficient.

Is the 125i Battery chainsaw waterproof for use in the rain?

While the Husqvarna 125i is built for durability, it is not waterproof and should not be used in active rain or heavy snow. The battery is designed with a horizontal "pass-through" housing to protect it from wood chips and debris, but moisture can damage the electrical contacts and the brushless motor. Always store the saw and battery in a dry, climate-controlled environment when not in use.

What other tools can I buy once I have the battery and charger that comes with the 125i?

Husqvarna battery tools run on an interchangeable battery system. Once you have the 40-B140 battery and 40-C80 charger, you can utilize them in a variety of other tools like our battery string trimmers, hedge trimmers, and leaf blowers.

Can the 125i cut down a tree that is 10 inches in diameter?

The 125i comes equipped with a 12 inch bar, meaning you could cut a 10 inch tree or branch with this tool. The operator’s manual states to not fell trees with a diameter that is more than two times larger than the guide bar length.

Is assembly required?

No, the 125i Power Axe comes fully assembled with the bar and chain on.
