    • Lithium Battery

    • Should always 2 batteries
Bought this for my brother. He said he loves the chain saw but original battery only lasted 5 cuts so bought another battery for back up

    • Straight forward
Other than a curious failure to charge immediately after using the tool -- I had to first let the battery sit for ~15 miinutes -- the battery works as expected. Recommended.

    • Chargeable battery
A must have if you have yard equipment, weedeater, or leaf blower that uses a battery.

    • Long lasting battery power
I really like that I can blow my good size deck and my yard patio and garage with driveway and still have battery power left. Wish it was a little more powerful but overall pretty good. A little expensive though

    • Works fine for this older Kobalt equipment
I can still only get about 20 minutes out of my Kobalt leaf blower with this battery, but my old original one finally stopped taking a charge. This is far better than nothing, and charges up and holds a charge. I have low leaf blowing needs as I live in a condo where most landscaping is taken care of. This is enough time for me to blow leaves off my patio on the 2nd floor and do some touchup work on the ground floor as needed. I'm happy with the purchase. I wish the cost was more reasonable, but limited options make this something to sustain a little more life out of the leaf blower. ... show more
