The Oregon PowerNow B400E 40V MAX Endurance Battery Pack is a 2.4Ah lithium ion battery pack featuring the latest high capacity cell technology. These lithium ion batteries combine high power with light weight. One of the main advantages of lithium ion batteries is no fade power, which means they delivery constant power up right up until complete discharge. They don't slow down or become bogged down as the battery runs down. The B400E has no memory effect, charge maintenance and full discharge is NOT necessary to retain consistent capacity throughout the life of the battery. The premium cell technology in the B400E enables it to last for approximately 1000 charge/discharge cycles. A completely discharged B400E battery pack will take approximately 2 hours to charge and it will last approximately 250 cuts per charge in 2-inch to 3-inch (5-7cm) diameter limbs. This performance may vary with user technique, chain sharpness, size and type of wood. One of the key advantages is that the B400E is always ready; lithium ion batteries retain most of their charge when left off the charger for months at a time. (Fully charged battery voltage measured without a workload is 40 volts. Nominal voltage is 37)
Top Customer Reviews
As a woman not used to lots of chainsaw cutting, this is easy to handle, feels solid and safely made, and so far is reliable for light yard cleanup or specific cutting projects such as treetop cleanup after logging.
The downsize is the cost, there may be competitors for battery operated chainsaws that are more affordable and do similar work. But this has decent battery life (heavy duty battery purchased) and the blade sharpener built into the saw is nifty.
I am glad I have it for when I need it, and recommend it if it fits your needs.
The 2.4 Ah battery was the largest-capacity battery available when I purchased the saw and later this spare battery. At this posting, I saw that a 4 Ah battery is now available. The 2.4 Ah battery is very lightweight for its capacity, provides a great runtime, and I would happily purchase it again. However, you may consider the larger battery, because I'm sure it will make the Oregon PowerNow tools even more awesome!
It is possible that just the charge LEDs are bad and the battery is still good but something major is wrong.
Supposedly they (Blount Company for Oregon, called number in user manual) is sending Fedex to pick it up and ship it back to them for free, very helpful, but $150 battery 3 months?
