Batteries & Chargers FAQS

Can I leave my battery in the charger after charging it?

Though you certainly can, we advise customers to remove the battery from the charger after it has been fully charged and to also unplug the charger from the outlet. The battery chargers do have auto cut offs to prevent it from overcharging but it's still best to follow good electrical safety practices. Doing so will also help prevent false defects readings and will allow the charger to reset itself each time it’s used to charge a battery.

Why do batteries cost so much more than the tool?

Batteries are the most important components for battery-operated units and happen to be the costliest items to manufacture and ship in any kit. We price our batteries with the cost of material, manufacturing, and current market pricing in mind. Full kits that include a tool, battery, and charger are priced affordably so that consumers can begin building a line of tools (24V, 40V, 60V, etc.) with battery compatibility and move forward purchasing tool-only units.

How do I store the battery? Can I leave the battery in the garage or shed?

We suggest storing the battery indoors and away from direct sunlight in a cool, dry area. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. It's best to store the battery with a full charge and to check on the charge every couple of months if it goes without use. 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 get the most out of the battery life.

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 that this switch requires a firm, direct push using the tip of your finger. If the button is not being fully engaged, the lights will not activate. The lights will only stay on for a few seconds and then will automatically turn off. Be advised, the lights might 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?

No, our batteries are only interchangeable with tools that belong to the same voltage platform (24V batteries only work with 24V tools, 40V batteries only work with 40V tools, etc.). The difference between batteries of the same voltage is the ampere-hour (Ah) rating. The higher the ampere-hour (Ah) rating on the battery, the more run time it has to offer.

Do all batteries of the same voltage use the same charger?

Yes! Each product line has designated charger models that can charge all batteries in that voltage platform despite Ah rating.

The charger indicates that my battery is fully charged but I was just using it and it depleted. Why isn’t it charging?

Putting a battery that was just in use onto the charger often results in a false full charge signal. Remove the battery from the charger and allow it to rest in a room temperature area for about 10-15 minutes before charging.

My charger is flashing red when I engage my battery. What is happening?

When the battery is inserted into the charger and the status LED blinks red, remove the battery from the charger for one minute, then reinsert. If the status LED blinks green, then the battery is properly charging. If the status LED is still blinking red, remove the battery and unplug the charger for one minute. After one minute, plug in the charger and reinsert the battery. If the status LED blinks green, the battery is properly charging. If the status LED is still blinking red, then this likely indicates an issue with the battery or charger and should be taken care of either with our warranty team or by means of replacement.
