Rated 5 out of 5 by from Work great I saw a lot review said battery last more an hour. I have Greenworks Pro 80V self propelled lawn mower. I set height on 2.5" and mulch on Palisade Zoysia grass. I used 2 batteries 10K square feet yard. I have a 5AH and 4AH battery. I used to have Cobalt 80V push lawn mower. It took 3 batteries to complete (80V 2AH).

Rated 5 out of 5 by from New Horsepower 80v and lots of watts This is now in my 80V stable. It is the long horsepower source, swappable to the string trimmer, mower, and finally the blower. Easy to use for me and wife too. And we never smell like gasoline. Well Done !

Rated 5 out of 5 by from Great addition to 80V mower AWESOME extended-life battery! My GreenWorks 80V mower came with two 2 AH batteries. Decided to upgrade to this 4 AH battery and now I can mow my entire 1/4 acre lawn without having to change batteries! Love it, great upgrade. Only downside for handheld tools it that it makes it that much heavier. OK with blower, but not good with trimmer/etc. Perfect fit for mower though.

what is the approximate run time with the 80 volt inverter with a small TV or similar appliance ?

Asked by: GWEIN
Hello GWEIN, To calculate the run time in hours, you have to divide the watt-hour rating of the battery that the inverter will be using by the number of watts that the product(tv, other small appliance) needs to run. For your reference, this 4.0Ah battery is 288Wh which will help with your calculations. *Please know that this is the general process for estimating run time and this is a very rough indication of actual run time. Actual run time may vary.*

Over the years when batteries sit not being used they go bad. You try to charge and it won’t accept a charge. What happens over time when these batteries sit for a few months? What are the best practices to keep them reliable?

Asked by: JBfish
Hello JBfish, Thank you for your question. 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. If it is being stored for a period where no use is expected, it is recommended to store the battery with a full charge. We advise checking 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.

Do the 80v batteries have smart circuitry management to prevent damage or reduced charging capacity to a battery left on the charger?

Asked by: ReagsterS
Hello ReagsterS, The charger will stop charging the battery once it's fully charged. However, the charger and the charger's LED light will remain on as long as the battery is inserted into the charger. We do advise that that you leave the charger unplugged from the power source after each use.
