I purchased a backup battery (Energup 40V 2500mAh Replacement Lithium.) for my Greenworks leaf blower. The backup battery worked for a very short time after which it never charged. It is not a Greenwork battery, my fault for not paying attention but it is suppose to be a replacement battery. Since my purchased was in February I never had a chance to check it out since it was winter, When summer came and I used it the replacement battery it worked for for a short time after which it would not even accept a charge. Since I missed the return date I could not return it. I don't know who the manufacturer is. It's called a Power Tool Replacement, made in China. The bottom line is if you buy a backup battery do not buy this one.
