40V High Capacity Lithium-Ion Battery is rated 4.3 out of 5 by 71.
Rated 5 out of 5 by from Long reliable life Our Ryobi leaf blower is a hit around our winery. It is always ready to go and the availability of variable speed is a great tool for us. Everyone here is impressed with the battery that lasts well through the job. The charger works great and it even lets us know it is ready with pleasant music! Our money well spent.

Rated 5 out of 5 by from Great power! I received this item as a gift. It holds charge very well. It doesn't take too long to charge and it is easy to insert. It is lightweight and the light-up indicator shows how much of the battery is charged. This is a pricey product, but well worth it as it can be used for multiple Ryobi battery operated products.

Rated 5 out of 5 by from No unavoidable issues I have about 7 of these batteries now with all the tools I have purchased, I did have one go bad, but the service replaced it. The best advice I have is to not leave them in direct sun. I know I have my blower, weed Wacker and mower out at same time, I have tried to store them in shade while in between uses.

Rated 5 out of 5 by from Battery replacement I love this blower which is very handy and has plenty of power for my needs. The battery would not hold a charge after 4 months of use. I contacted Ryobi and they immediately sent me a new replacement at no charge and no shipping charge. I'm happily back clearing the yard, garage and sidewalks.

Rated 4 out of 5 by from Love not having to use gasoline or a power cord. Have a corner lot and run out of power so have to recharge it. It does recharge quickly. My first charger died after a few charges. Home Depot did replace it as was under warranty. I sure hope the replacement one last much longer.

Rated 2 out of 5 by from The power is great with this battery, however, I have had to replace two already because the battery started flashing that the battery was bad. I have only had the blower and battery for not quite two months. Those batteries should last longer than that.

Rated 5 out of 5 by from Terrific battery This battery has as much power as my gas line edger/trimmer had with all the hassle. I have nothing against gasoline engines but this one saves time, money and is easy to put into any Ryobi tool. GREAT BATTERY. GREAT PRODUCTS!

Rated 5 out of 5 by from Just what I needed I purchased this battery to add to my collection of batteries to operate my mower, weed eater, and edger. It was exactly what I needed. I can trim and edge my entire yard with one battery and still have two bars of power left.

Rated 4 out of 5 by from Great upgrade to the 40V tool line. Several tasks I have performed have used up the charge on the original 40V battery requiring a swap to a fresh battery. This 5AH model has eliminated this swap out as it appears to have about twice the run time.

Rated 5 out of 5 by from long lasting charge bought this battery to have it on hand when my other battery needs to recharged, and I need to complete a project without stopping. I an very satisfied with the results and recommend it to potential buyers.

Rated 5 out of 5 by from Great storage!!! Needed an extra battery as I have a lot of trimming. With two batteries, I can do all of my trimming and still have power left over. With a gas trimmer, had to re-fill the tank half way through the job.

Rated 1 out of 5 by from Awful Have had this policy for six month. It won't hold a charge long enough from the day I bought it. Now it won't even charge to work. I purchased both blower and trimmer and now they just sit in garage.

Rated 5 out of 5 by from Great System I started with the 40 volt trimmer 3 years ago. 2 years ago I bought the 40v blower and the 40v chain saw. This year I bought the 40v tiller and the 40v lawn mower for the little patio area in back. I have six 40v batteries now and everyone of them works like new. I was sad to see people had experienced problems. Be sure to never ever store a LION battery on empty, always store it charged or better yet half charged. Half charged is charge neutral and it should last forever. I have about a dozen 18v tools and about 5 or 6 batteries some as old as 7 years old and I cannot tell any differences between the new batteries and the old batteries. After the batteries charge do not leave them in the charger. And remember never store a discharged battery. The chemicals will crystallize and it will ruin the battery. My wife uses the 18v trimmer, 18v blower and little 18v chain saw while I use the 40v versions. I would love to lay my hands into a dual 40v chainsaw or 80 volt chain saw soon with 20 inch bar. The neatest thing is how quiet the tools are and how reliable they are.

Rated 5 out of 5 by from Good long lasting power I bought this to give me the finishing power the smaller battery didn't have and I have been very satisfied ever since. Wish I had one more to make my trimming and sweeping happen without a recharge.

Rated 5 out of 5 by from Long Lasting I have been using these with my mower for 1 1/2 years and they charge quick and can do a yard with one battery and normal grass height. We liked it so much we bought the 40V snow blower as well.

Rated 5 out of 5 by from More powerful I now have 4 batteries and 2 chargers. 1-4015 and 3-4026 they do a good job. I use them on a blower and chainsaw. I really like the extra power of the 40 volt as compared to the 18 volt system.

Rated 5 out of 5 by from Excellent charge holding I bought a second battery so that I could mow the entire 10,000 square foot lawn without stopping to recharge. Very useful; makes it possible to mow only during the cool part of the day.

Rated 1 out of 5 by from Poor quality control Thank god for extended battery warranty as I have now gone through three batteries. The last one lasting only three weeks and two uses. Ryobi needs to have better quality control...

Rated 1 out of 5 by from Defective I bought this tool less than 2 months ago, and defective light flashes. It won't charge at all anymore. It's heavier than I would like, and it does lose power before it dies.
Date published: 2016-11-05
Rated 5 out of 5 by from short charge time I like the short charge time. I use it in the chain saw and the expanding pole saw and trimmer. Does the job. Don't bother with the lower capacity half size battery.

Rated 5 out of 5 by from Amazing I got three cuts on my medium size lawn and the battery still did not need a charge. good power, long lasting and quality construction make this a superior product.

Rated 1 out of 5 by from First one a dud The first one I bought ceased to take a charge after mowing my lawn 5-6 times. I called Ryobi and they immediately sent me a new one. All is well now.

Rated 5 out of 5 by from Long Lasting I bought this about a month ago and usedfit to help clean up a large parking lot. I was able to use the blower for about 2 hrs. Without it going dead.

Rated 5 out of 5 by from Powerful and quick power. I love my Ryobi 40 volt tools, powerful, long lasting and when you need to charge these batteries charge faster than anything I have used before.
