Questions & Answers

What is difference between 5Ah and 3Ah?

Asked by: Frank
The Ryobi 5Ah battery is used in the Ryobi 40-volt line of products. My research concluded the Ryobi 3Ah battery belongs to the Ryobi 18-volt line of products. I am new to recently researching the Ryobi pole saws, Expand-It line and batteries so if I have missed something please reply.

has anyone else had a issue with this battery only running for 5 minutes then shutting off on a fully charged battery?

when using this battery in the push mower it when using the battery in the mower it will run for 5-15 minutes then just shut off and then the only way to get it to work is to pull it out and put it back in the mower then it runs good again. Is this just me or does it happen to others?
Asked by: THDcustomer
Yes, I am now on battery #3; the first two had exactly that problem. Ryobi's 40V tools would be great if they would manage designing a reliable battery circuit; I almost doubt that the batteries themselves can be that bad, i.e. my money is on the control boards. Both previous batteries died after less than 10 uses. I wished I would have bought the corded variant.

How long does it take to charge this battery? If I run through the whole charge mowing my whole lawn, do I have to wait until the next day to finish mowing, or does this charge quickly enough to go back out in a few hours to finish?
Asked by: Christina
No, I have found I can charge it for a couple of hours & get another 1/2 hr mowing done.

Can I leave my 40V or 20V Ryobi 5Ah or 2.6 or 1.5 Ah Lithium battery plugged in the Ryobi charger for extended period while not in use in the tool? I though those chargers have smart circuit to prevent overcharging and damaging the battery.
Asked by: Carlos
It is best to unplug once you are fully charged and also after use let the battery cool down some before plugging charger in, The book will tell you to remove from charger once it is charged. I have had several batteries die prematurely because they were left on the charger and plugged in. I used to leave charge them in the garage but now I charge them in the kitchen where I can see them so that I can unplug as soon as they have charged.

40-Volt Lithium-Ion 5 Ah High Capacity Battery is rated 4.5 out of 5 by 1672.
Rated 5 out of 5 by from This should be the standard battery for at least the mower. I have been using the 40v mower and weed eater for about 6 years now. I got the mower that came with the 2 batteries and ended up having to buy the weed eater mainly because I did not want to spend $100 on just a battery. It took all 3 batteries to do my lawn and weed eat. That was brand new as they got older it was taking 4 1/2 batteries which meant to finish had to charge them. I have to say with the old batteries I did miss a gas mower. If I would have had this battery from the start I would have been much happier and would have never missed the old gas mower. The one battery did the entire back yard and most of the front. Not to mention there were places where the other batteries would bog down and make me go at a snail pace or go over an area twice. The 40v 5ah did not do this I could go at the same pace for the entire time. If you own the mower I would highly recommend this battery. I don't understand why this battery is not sold in my store. I can only get the regular one.

We're so fed up with companies that don't want to acknowledge their warranty or help you with a known issue, which in this case is a sticking Ryobi 40V battery. I just got off the phone with Ryobi to ask what I can do about the 40V 5aH battery sticking in the Ryobi lawn mower. This weekend it took us a lot of effort, removing the plastic cover over the battery, etc. before we got the battery out. No way are we this back in. The Ryobi rep was totally unhelpful, rude, and sounded like he was chewing gum the entire time we spoke. He said it could be sticking because there is something wrong with the frame of the mower, despite my repeatedly telling him we have two other aH batteries that never get stuck. He told me to look in the machine to see what's going on, but was silent when I asked him what I would be looking for??? He was also silent when I asked about replacement under warranty, except he told to take the battery and mower to the to the tool rental desk at Home Depot. Thanks for nothing, Ryboi, and for the $150 + tax paperweight.

The Ryobi 5 Ah batteries met my expectations and continue to perform very well. I can mow my small yard (about 7000 sq ft) and then use the same battery to trim everything as well and still have at least 25% power left in the battery. I bought 2 of these batteries so I can also use 1 battery in my Ryobi hedge trimmer to trim the bushes/hedge around the yard and then clean it all up with my Ryobi blower, all without stopping in the middle of a job to recharge a battery. I still have the 4.5 Ah battery that came with the Ryobi 20" mulching mower, so I always have a 40V power supply ready to go. The only problem I have encountered is with the mower handle clamp on the right side (where the start & safety switch cable runs) popping loose and that causes the mower to shut down. It took me a little while to figure out why the mower was shutting down multiple times during a mowing job as the loose clamp wasn't obvious. But I will address that issue in a review of the mower. These 5Ah batteries are great!

Rated 2 out of 5 by from Want to like it, but not enough charge for my yard 2 Years ago I bought the Ryobi 40v 16" lawn mower, and was amazed at how I could mow my yard with almost 1 charge, leaving about 10% for the next day so I could re-charge the battery. Last year I decided to buy an extra battery so I could avoid the 2 day affair of re-charging the battery and I could do it in one afternoon. That lasted a few months. Now with a 5 AH and a 4 AH I can't finish mowing my lawn (and it is not huge)... I am sad that I am feeling that I need a 3rd battery to be able to finish up in a shift. I use a lot of Ryobi tools (have a collection) but these 40V batteries are expensive and are not keeping up with my yard... [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Turns the mower into a power house! I wanted to get my parents something for helping me out and finding them a gift is always hard. They have both the Ryobi 40V mower and trimmer (and lots of other ryobi stuff!) They enjoy them but I noticed that it was going through batts pretty quickly and when I used it at their house the power was not gas type power. So I was reading reviews on this and thought it would be a nice gift. Turns out it was! My mother used it the first time and called me about how amazing it made the mower and it had power like a gas mower. Plus it got through so much more of the yard without having to change batts! She mowed again yesterday and I got another call raving about how amazing it was. They have not tried it on the trimmer yet, I am thinking they are afraid it may be to powerful. ;) I will try and give an updated review once they have had it a little longer to see how it holds up. So far it is a good purchase. It is a little pricey but all 40V are.

We have one battery that came with the electric lawnmower, but that cannot get through our whole lawn which is average size. And often when it is time to mow, you have to get it done before the next rain or when you have the time! So we charge this second battery using our charger from the electric trimmer and then we have both ready to go when it is time to mow the lawn. We have to wait to do our trimming though....but we are VERY HAPPY with this purchase. It allows us to get the job done in one mowing!!!

I need a second 40V Lithium battery for my Ryobi electric lawn mower due to the size of my yard. One just does not quite make it. I got this second battery rated at the same amp hour in order to have two interchangeable batteries charged at all times when I mow. Yes it is expensive, but I get the yard mowed efficiently and so the cost is worth my time. No more waiting for the original battery to get recharged.
