Greenworks40V 5A Rapid Charger，for All Greenworks 40V Battery

I purchased this after misplacing the one that came with the weed wacker. It works perfectly. I can't see about rating it for longevity, since I've only had it for a short period of time.

This product works very well.

Purchased this because I couldn’t find my old charger for my blower that I purchased a couple of years ago. Charged it quickly and I was able to do blow out my garage!

I use this battery as a backup in a Greenworks blower. I really like it since it is lighter than the OEM battery at a great price. After 2 months, the battery started dying after 5 minutes of use. Additionally, during charge my charger was blinking red, which indicates a bad cell. It was beyond the 30 day return window for Amazon. I was prepared to write a bad review. However, I reached out to the company and got a fast response. They asked a few questions about my use and then shipped me a new battery.Here are some things that I have learned. A blower has variable draw on the battery -- stop/start/stop/start as I am blowing areas and then walking to other areas. This shortens the life of the charge. I am sure there is a lithium battery expert that can explain why. I get longer life from the battery if I set the trigger to always on -- even while walking to another area. I found this to be true of the OEM battery as well. Bottom line: the new battery is working well and makes a great backup.

Everything is great
