40-Volt 4-Amps 4.0ah Rechargeable Lithium Ion (Li-Ion) Cordless Power Equipment Battery for Kobalt

This was a secondary back up for a mower I already have. Helps me finish mowing the yard in one day. Very helpful to have. Recommend.

This new battery is working great; probably 30-40 minutes on one charge, not using the self-propelled feature. The battery we got with the mower started limping in the 3rd year. We can still use it in this its 4th year, but it only charges 4 lights worth and gives about 10-15 minutes on a charge. However you measure it, the battery is well worth the price, to avoid using gasoline.

It don't last as long as I would like for it too.

Works well...lasts much better than the 2.0

Exactly as described and last much longer than the original 3ah.

Great product

My original battery was not lasting as long as it used to, so I decided to find a new battery for my Kobalt blower. I saw the 20 volt and the 40 volt and decided to spend a little more for the 40 volt to see if it was stronger. The 40 volt is definitely the way to go. It made my blower much more powerful and last way longer than the 20 volt original battery. It is a little heavier than the 20 volt but is worth the extra weight. I honestly don't even use the 20 volt battery anymore. The price is a little high but in the end, totally worth it.

The battery never worked. It was dead the minute we got it and put it in the charger. It never charged so we could never use it.
