Are kobalt 40v and 80v batteries interchangeable

Editor’s Note: This is the original text from our reviewer when the Kobalt 80V Chainsaw came out. However, the ratings have been updated to reflect its performance in our recent chainsaw shootout.

We’ve had the opportunity to see several new lithium-ion powered chainsaws this year. What started as a novelty has developed into a serious landscape tool and even professionals are surprised at the power that’s being delivered through these small cells. Serious contenders for pro attention start with Husqvarna’s 36V model, jump to EGO’s 56V solution, and end up with Greenworks and Kobalt at 80V. I reviewed Kobalt’s 40V chainsaw last year. It was certainly capably of handling the homeowner’s tree trimming, but I expect more out of the Kobalt 80V chainsaw. I’m going to be taking the 80V model on a field trip into the woods. Before we set off, let’s take a look at what this model has to offer.


Kobalt 80V Chainsaw First Impressions

Lets start with the obvious improvement- the battery. This bad boy offers an 80V lithium-ion rechargeable battery. As a part of the 80V series of Kobalt outdoor power equipment, the battery is interchangeable with the 80V mower, blower, and string trimmer. The 2.0 Ah battery fully charges at 30 minutes, which I found impressive for 144 watt hour battery. Being battery powered, there are the benefits of less noise, no fumes, and no mixing of gas and oil compared to a gas chainsaw.

If you’ve looked through the stores, there are some undeniable similarities between the Greenworks 80V Chainsaw and the Kobalt 80V Chainsaw – and their entire 80V line ups. So yes, there’s some technology sharing going on. Does that make them the same exact tool? Not necessarily.

Kobalt 80V Chainsaw Performance

So how does 80V translate in cutting power and performance? As an intermediate chainsaw user, I thought that it had plenty of power from some basic initial testing I put it through. It cut faster than the previous 40-volt model and had a noticeably lower kickback. The reduced kickback lowers the intimidation factor of the chainsaw when moving up 6 inches in bar length. I found it to be well balanced and easy to use. But don’t just take my word for it.

I had the opportunity to share the chainsaw with a professional Florida woodsman experienced with gas-powered chainsaws. He initially doubted that a battery powered chainsaw would have the cutting power to handle professional tasks. After the first pass, all doubt he had was cut off (pun intended) as it went through a sizable downed pine tree. With the improved power and 18 inches of length this chainsaw has the versatility to be used in a variety of situations.

Out on our field trip, we were able to see most of the safety features in action. The Kobalt 80V Chainsaw is equipped it with multiple safety features that even a former elementary hallway safety patrolman like myself can appreciate. Included in that group are an on/off button with audible beeps, trigger lock, and electronic chain break/guard with audible beeps – wow, my head just exploded! A cool safety feature that will also help save battery life is the automatic shut off. If the chainsaw is on idle for 15 seconds it will automatically shut off. It might bother some, but since it’s easy to turn on with a push of a button, I didn’t mind that feature at all. While in use, if a kickback or error occurs the electronic chain break engages and stops the chain with audible beeps to notify the user that something has caused the saw to stop. We had pinched bars, idle time, kickbacks, and all of the things that make tree cutting fun – and the safety features worked flawlessly.

The only down side to a battery powered chainsaw is that the run time is limited to the battery life. We didn’t test the full run time, however I’d recommend havingan additional battery on hand for a full day of cutting. Like other chainsaws, I did noticed some bar and chain oil leakage when stored flat side down position.


Final Thoughts

Are kobalt 40v and 80v batteries interchangeable

The Kobalt 80V Chainsaw was better than expected. With 80 volts, brushless motor, and an 18″ bar, it can and should be more than just a backyard chainsaw. It’s not really going to reach the professional forester. Some pro landscapers that offer tree trimming, storm cleanup, and other occasional applications will find it useful. Where I really think it’s dialed in is for the property owner that needs to maintain a large number of trees. Whether it’s general maintenance, storm prep/cleanup, or even taking down medium size trees, you won’t have to worry about how long it’s been sitting or if you remembered to winterize it. Just charge the battery and get to work.

There is no doubt that much has improved since the release of its predecessor chainsaw. It boasts a new ergonomic design, improved safety features, and of course, a lot more power. Overall, this chainsaw has features that I liked a lot – quick on/off, safety considerations, good weight/balance, and less noise compared to a gas powered chainsaw. These were enough to get my approval. The Kobalt 80V Max is definitely worth a look if you are in a market for a chainsaw to use in the backyard, and perhaps into some occasional professional use.

Can you use 80V battery on 40V Kobalt tools?

All Kobalt 80 V batteries are NOT interchangeable. I have a Kobalt 80 V battery for my Kob… Q: my hedge trimmer cuts out after about 4 secs.

Can you charge a Kobalt 80V battery on a 40V charger?

Sorry but it will not. You need the blue color 40 volt charger. This is not compatible wit…

Can I use a 80V battery in a 40V tool GreenWorks?

A: Our 40V battery cannot be used with an 80V charger/units and vice versa. Greenworks manufactures a range of voltage platforms from 24V - 80V, each voltage platform has its own set of interchangeable tools and battery but are not interchangeable across different voltage platforms.

What is the difference between a 40 volt and 80 volt battery?

The difference is the 80v has a slightly less power (or amps) drain (P= IE) than the 40v, but negligible for practical purposes.
