        Comments about 40V 4 Ah Lithium-Ion Battery:

        Green works will discontinue this battery, eventually, although a battery manufacturer may provide it for those people still operating the respective model of cordless mower. The mower and batteries were a great buy and are reliable. Although this battery has a 2 hour charge time it is still shorter than the original design that took 3 hours. The price was very reasonable and no trouble with the battery operation.

              I use this for my 40V Cordless 19 in. 3-in-1 Lawn Mower, at the beginning I can work on my lawn for around 1 hour. After three month (used 4 or 5 times each month), the battery can only hold half an hour now.

                Q:

                I purchased a greenworks mower with charger and 2 40 v lithium batteries. Love it but now the batteries will not take a full charge..it is less then1 year old. Not sure if it is the charger or batteries. Red and green lights stay on. They have been stored inside for 3 months. With a full charge before storage.

                  I have worked with battery technology for the past several years, and one thing to remember is that lithium batteries should never be stored with a full charge. At the most, half a charge is acceptable. also, never charge a lithium battery when hot (allow them to cool down first). The batteries should be fully charged just prior to use. Storing them with a full charge will drastically reduce the life of the battery and its ability to maintain a charge.

                  You do still have the manufacturer's warranty. Please call Greenworks directly at 888-909-6757 to get the items repaired or replaced under the warranty.
