If your yard is flat, and not too large, one should be enough. Our yard is hilly and we have two for the job.Three would be better.

How low should a 40v battery go before recharging?

Asked by XXX October 18, 2020

Answers

I have let mine run down to zero. And I have recharged when 3 of 4 green lights were on. Lithium-ion batteries are not like the old Ni-Cad batteries that were picky about when to recharge. Lithium batteries can be recharged at any level.

Can you leave the battery in garage in winter?

My 40 volt battery's 4 led lights are on even after taking it off the charger, and will not power my trimmer. Any ideas?

Sounds like you might have an internal short in your battery. Do you have a volt meter? You could check voltage. There is an 800 number you call call and they'll help you out. I've had good experience with the help line. Good luck.

If all 40v batteries are interchangeable I can use any regular 40v 6ah in my new propelled mower instead of a Huge HP?

Asked by Vashon September 13, 2020

Answers

There are a couple different 40v models. The 2ah, 4ah, 5ah, etc. The bigger the number the longer the run time. They are all interchangeable though. So use what you need.

I am finding that I no longer get full use of my fully charged battery.

Two things could be happening. One, the battery, durring the warm Summer months, could be just overheating and it reaches the automatic shut down tempurature before running out of power and this is normal for this battery. Two, One of the 20 - 18650 battery cells could be week and the voltage is dropping to low to run the lawn mower and it shuts down to protect the battery from becomming a 'Brick" if totally discharged. The voltage will start off high, after a fresh re-charge, at 42 volts, but, over the course of a "Run", the voltage will drop down to 34 volts. A fully charged 18650 lithium ion battery is 4.2 volts even though it is rated at 3.7 volts. There are two balanced string of 10 - 18650 cells in the Ryobi Battery pack. If one cell is week, the battery pack voltage could drop by 3.7 volts causing it to reach the 34 volt cut off after only partial use. The battery and charger needs to be tested at your local Home Depot Tool Rental and Service Center at you Local Home Depot Store. But before that, consider placing your 5 amp hour Ryobi Lithium batteries in a cool 45 degree F. place , like your refrigerator crisper, for 30 minuts before use so they start off cooler and run the lawn mower as usual to check run time. If it is just overheating, then starting cold will allow you to get the full run time of the battery and there most likely nothing wrong with it. However, if it still stops to soon then it might be one of the 18650 cells. Remember, your battery has a 3 year replacment warrenty, from date of purchase, so bring your original receipt with you.

I used this battery for about 2 years for lawn mower and cutting tree branches. Good and strong power. Easy to recharge and satisfactory amount of time last long. After I used with 14 in chainsaw and cut the 7 inchs tree root, battery was unable to recharge and defective . I don't have problem with 4-5 inches tree branches.

Ryobi battery problem
I have 4 tools, leaf blower, weed trimmer, leaf vac, and chainsaw that run off of this type of battery, Within 1-2 years of purchasing these tools/batteries online and some from the home depot store, only one (1) of the four (4) batteries work good, two have failed completly, and 1 only works 2-3min now, the only good one lasts me about 15min. There’s no reason why these batteries should have failed so quickly. Ryobi need to fix their faulty batteries.

If your battery won't charge and flashes all four LEDs when you press the test button, try this first to reset it.

suck
i have the Ryobi lawn mower, weed eater and blower all three batteries absolutely suck. All 3 can't keep a charge. The lights will say they're fully charge put them on the equipment and last 5 minutes (if lucky) 1 of them are the 3Ah and 1 is 4Ah and the other 5Ah. They equally suck.

RYOBI is the best product out there. Large selection of 40v power tools. I hope they can offer a combo blower & vacuum unit. A trade in/upgrade option would be great.

I lacked about 20 minutes of getting my entire yard done. Bought an extra battery and now have enough power to do it all in one try. Would sure recommend the Ryobi battery mower to any and all that are thinking about getting one.

Long Lasting power. Lot's of Power.
Customer review from ryobitools.com logo
I have the 20" Ryobe 40v Battery powered Mower and wow am I impressed at the raw power from the 40v battery. My lot is 120' X 85' and the battery lasts until the end with a pinch of power to go. I should mention that my mower is the Self Propelled model. Recharging the battery takes about 2.5hrs and is easy to put into the charger. I have taken a break between my front yard and my back, gave the battery a charge during that time and that extra charge inabled me to even cut my neighbors front yard. A good friend has a few 40v Ryobe yard tools. In the weedwaker it has power to cut even thick grass and the Blower puts out intense power. At the shop I've seen it last for a long time before needing a recharge. I also have a line up of Ryobe 18v Drills and equipment, the 40v blows it away, yet I'm very happy with my Ryobe battery tools. Sure there are several brands to choose from, but using Ryobe Tools for a few years, it's among the best you can buy. You won't be dissapionted when you buy and anything that uses the 40v battery will amaze you with the power and long battery life. I put all the Ryobe lineup as Recommend to Buy. The 40v system, absoluitely! You won't return it, you'll love it. [This review was collected as part of a promotion.]

Bought this as a back up for my mower. Works great. Also use it for my power head and attachments. Just bought a chainsaw that uses the same platform. [This review was collected as part of a promotion.]
