Frequently Asked Questions

  • Can I leave my battery in the charger after charging it?
  • The battery chargers do have auto cut offs to prevent it from over charging. However, we do advise customers to remove the battery from the charger after it has been fully charged and to also unplug the charger from the outlet, as this is good electrical safety practice to do so. This will also help to prevent false defect readings and allows the charger to reset itself each time it’s used to charge a battery.

  • Why do batteries cost so much more than the tool?
  • The battery is the most important component for a battery-operated unit. Please be assured we price our batteries with the cost of material, manufacturing, and current market pricing in mind. Batteries are the costliest items to manufacture and ship in any kit. Full kits including a tool, battery, and charger are priced affordably so that consumers can begin building that line of tools and move forward purchasing tool-only units. When you purchase batteries on their own, it is more notable the cost that they carry.

  • How do I store the battery? Can I leave the battery in the garage or shed?
  • When the battery is not 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 out of the battery life.

  • My battery is stuck in my tool. How do I get it out?
  • 60V/ 80V Products: To remove the battery, push and hold the battery release button. Then, pull the battery pack straight out. In some cases, if the springs underneath have gotten locked down you might have to give a small push to the top of the battery to re-engage them to help the battery pop up. The battery pack fits snugly into the product to prevent accidental dislodging while in use; it may require a strong pull to remove. Before use, be sure that the rails on the battery and product are free of debris that could cause the battery to get stuck. 24V/ 40V Products: To remove the battery, press the latch button on the battery pack down and hold. Pull the battery pack out of the handle. The battery pack fits snugly into the product to prevent accidental dislodging while in use; it may require a strong pull to remove. Before use, be sure that the rails on the battery and product are free of debris that could cause the battery to get stuck.

  • How do I check the charge on my battery?
  • Press the battery capacity indicator (BCI) button located at the end of the battery. The lights will illuminate according to the battery capacity level. Please note this switch does require a firm direct push using the tip of your finger. If the button is not being fully engaged, the lights will not activate. Please also be advised the lights only stay on for a few seconds and will automatically turn off. Another reason the lights will not power on is if the battery is completely depleted of power and needs to be charged.

  • Can I use any Greenworks battery in any Greenworks tool?
  • Our batteries are interchangeable with tools that are of the same voltage platform only. The difference between batteries of the same voltage is the ampere-hour (Ah) rating. The higher the ampere-hour (Ah) rating on the battery is the more run time it has to offer.

  • Are there certain tools that can’t accept all same voltage batteries?
  • There are a few exceptions. • Our 80V 20” snow thrower models 2600402 / 2605202 / 2601302 manufactured prior to September of 2017 can only use 2.0Ah or 2.5Ah battery models. • Our 60V 8.0Ah battery model 2957102 cannot be used in the following tools due to the height: dual-port lawnmowers, pressure washers, or the wet/dry vacuum.

  • Do all batteries of the same voltage use the same charger?
  • Yes, they do. Each product line has designated charger models that can charge all batteries in that voltage platform, no matter the Ah rating.

  • Does battery temperature matter?
  • The temperature of the battery prior to use should not be too warm or too cold. For snow throwers if the battery is too cold it may not be operatable. Allow the battery to get to room temperature prior to use. For our other tools allow the battery to cool down prior to use if it’s too warm. To avoid battery temperature issues, batteries should be stored indoors in a dry and cool location. Information on battery storage and temperature will in inside your owner’s manual.
