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.

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.

Unreliable Battery and Terrible Supplier

My Kobalt battery was defective from day one. It would never fully charge (only 3 out of 4 LEDs). Kobalt advertises a 3 year warranty from defects. However, the Amazon supplier would not accept a product return and asked me to deal with Kobalt directly and pay for return shipping. Lowes is fully aware of the unreliable nature of these batteries and offers an immediate replacement or refund in the store. I wish I had bought it from them. DO NOT ORDER KOBALT BATTERIES FROM AMAZON!
