Hello TN Mike, Our apologies for your experience, the most common issue related to a unit only working for a few seconds is connection or battery charge. If the charge is full, please make sure the battery clicks into place. Intermittent function can occur when the battery has not been correctly seated into the compartment on the tool.

Hello aquari8801, The run time is determined by the Ah rating of the battery. The higher the Ah rating is, the more run time the battery has to offer. All Greenworks 60V batteries are compatible with our 60V tools. When using a battery-operated unit, it's important to adjust your mowing techniques to make the most out of the battery life! It goes without saying that that the harder the unit works, the quicker the battery drains. Here are a few mowing tips! 1) When cutting thick grass, reduce walking speed in order to allow for a more effective cut and a proper discharge of the clippings. 2) Only mow 1/3 of the total grass length at a time - no more. For a healthy lawn, always cut off one-third or less of the total length of the grass. The average lawn should be approximately 1 1/2 to 2” (3.8 to 5 cm) long during cool months, and between 2" to 3 1/4" (5 cm to 8.3 cm) long during hot months. 3) Mow when the grass is dry. As this is an electric unit, mowing wet/damp grass is a safety issue. However, ensuring the grass is dry will also help the grass cut cleanly and discharge appropriately. Wet/damp grass carries more weight and will mostly stick to the blade/motor shaft and will not appropriately discharge or cut easily. 4) Make sure the battery is cool before use. When the battery will not be in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. We hope these tips will help!

Hello Hruby, The overall battery life is dependent on many factors such as where they have been stored, charged, and handled. When the battery will not be in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. It is recommended to store the battery with a full charge, and if it is being stored for a period where no use is expected, to check on the charge every couple of months. If you notice the charge has dropped, we advise charging the battery back up to full before returning it to its safe storage place. Following these steps will ensure you receive the most of the battery life.

Hello TameTheGame, Yes, it will.

Hello Dwk3, Greenworks batteries are not compatible with Snapper tools.

Hello SwapZilla, Greenworks does not have a 56V line of tools. We kindly ask that you refer to the model number printed on your battery and repost this question. You may also contact us for assistance at 1-888-909-6757 or submit an email to info@greenworkstools.com.

Hello SAW46, With most tools, 30 minutes when using this battery is a pretty average run time. The run time varies depending on the tool that it is being used in but also the load acting against the unit while in use. We would be happy to investigate to see whether your run time would be considered average; please kindly contact our customer support center at 1-888-909-6757 or submit an email to info@greenworkstools.com.
