## Description

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)

Review: Five Stars - holds up nicely, fast re-charge time, great combo with CS250-E6 saw.
Review: Battery does not hold a charge after 2 months - Battery doesn't hold a charge. Very disappointed

### ⭐⭐⭐⭐⭐ Five Stars

Battery doesn't hold a charge. Very disappointed

### ⭐⭐⭐⭐⭐ Great extra battery
*by D***D on March 27, 2014*

I own the OREGON 40 Volt MAX* CS250-E6 Chain Saw Kit with 2.4 Ah Battery Pack and after using the saw off and on for about a month, decided to invest in a second battery. Having a second 2.4 Ah battery has made the saw near perfect for most uses After depleting a battery, I will put in on the charger and grab the second one. After "continuously" cutting brush or bucking logs, the battery has completely recharged when I go to swap batteries again. 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!
