Greenworks 40V 2.0Ah Lithium-Ion High-Power Battery(Genuine Battery / 75+ Compatible Tools)

Tried to charge but wouldn't charge. Tested 3 chargers and known good batteries & confirmed faulty. Just ordered exact replacement, as all aftermarket batteries are likely to be made in China (this one is made in Vietnam). In Asia, Japan and Taiwan seem to be the only countries that hold high standards and stringent quality control (and even those two countries are not perfect, and standards in Japan are falling short due to the majority of workers being forced to work as part-timers and increasing number of foreigners with poor work ethics/language barriers). These batteries, like any other rechargeable batteries, are consumables and after certain charges they no longer hold charge or wouldn't charge, which is normal. My first Greenworks 4.0AH battery just died after like 20+ charges/6 years. Their 6.0AH was the best, but they discontinued it and replaced it with 8.0AH, which is about $250. You don't spend $250 on a battery that is known to go bad after several years, so 5.0AH at $150 is a good choice (anything with less AH is not suitable for real life use).

Just as described!

I bought this for an extra battery for my greenworks lawnmower and although the battery is fully charged - mower turns off in about ten seconds of use. This battery is recommended for use in their mowers.

On a full charge it lasts for maybe 20 minutes on a good day. For a battery that costs almost $200 you would think it would last longer. Very,very disappointed.

Wrong battery for a Generac Leaf Blower it did not fit. I had to return it..
