Do the 18 volt batteries come with a warranty or can they be repaired

Asked by Dj January 1, 2021

Answers

Hi Dj, Thanks for your question on the RYOBI 40-Volt Lithium-Ion 2.0 Ah Battery OP4020A. The 18 volt batteries come with a 3 year warranty and cannot be repaired. They are replaced during the warranty period. I hope this helps and let RYOBI know if we can assist you in the future. Eve

Do the 40 volt batteries have a warranty I've had mine less than 2 years and it won't charge.

Asked by Dj December 29, 2020

3 years on batteries from date of purchase either alone or in a kit. Take your battery and your charger back to Home Depot's Service or tool rental desk for warrenty replacment along with your original receipt. They will test it first, on your charger, to make sure it is not the charger then sent it out for a replacment. There is a refundable fee for this service so put the fee on your home depot credit card and you will see the credit later. This fee covers the postage and handeling but Home Depot will refund it if Ryobi verifies it is under warrenty. When your new battery arives, they will call you and you can go in and pick it up with the "Claim Check" you are given t drop off. The replacment battery could be a re-conditioned one and the original 3 years from your date of purchase will continue on your replacment battery. The Ryobi 2 amp hour 40 volt battery contains 10 - 2,000 Miliamp 18650 lithium ion batteries and if just one of those 10 batteries fails, the unit will not take a charge. The other 9 batteries will still be good but you must tear apart the case to un-weld them and use them in tactical flashlights or other 18650 battery using devices. Do not try to repair the Ryobi 40 Volt battery yourself.

how does this compare to a 2.6

Asked by lucky October 7, 2020

Answers

The 2.6 AH has 2 0- 1,300mah 18650 batteries and the 2.0 has 10 - 2,000 mah batteries and is lighter and is great for a tool you have to hold over your head to use like chain saws or hedge trimmers. Refered to as the "Slim" battery, the 2.0 replaces the 1.5 that was sold a few years back. I purcheased 2 for my chain saw for work trimming up in the trees. I can also use any of the other more powerfull batteries in the chain saw when "bucking-up" wood on the ground.

Asked by Richard July 4, 2020

Answers

I take mine out of the charger when it's charged. I don't know if it's better, but the green light stays on when it's finished charging, giving me the impression that electricity is still going to the unit and that's just a waste if electricity. I actually remove the battery from the charger and unplug the charger... all in the name of Less Wasted Energy. So, in that way, yes, it is better to take it out of the charger.

This battery has really good power for its size and weight. I much prefer to have two of this size battery instead of one larger more powerful one. I find having this lighter battery makes the work easier and if I have two of them I can have one in the charger while I am using the other one. I have had it for a few weeks and used it with my hedge trimmer and it provided all the power I needed to do the job. I wasn’t sure how long the battery would run when it is fully charges so I tested it with my Ryobi Jet Fan Blower running continuously and it ran for 12 minutes before I heard a change in the pitch of the blower. It probably would have run a little longer, but I feel this represents the amount of time the battery would continuously run this blower at maximum performance. I tried recharging the battery right after shutting the blower off, but the charger wouldn’t charge the battery. I checked the instructions and it said the charger wouldn’t charge a battery if it was too hot. After the battery cooled, I tried again and the battery took a full charge.

I have used this battery for only a few weeks. And so far I am very impressed with its capability to deliver the power required to run my RYOBI tool to its maximum capability. I am also impressed with its run-time between recharges. To date, I have been able to finish every task before the charge ran out. So I do not have available a good time estimate of how long a full-charge will last. After finishing a job where I am using the battery in a tool I place it in the recharge base to bring it up to full charge in preparation for its next use. However, I have timed how long it takes to fully charge the battery pack when only one of the four charge level indicators are lit and that is approximately 1.5 hours. The battery comes with a three year limited warranty. And like all the RYOBI products I am currently using it appears to be well-built, so I expect it will provide many years of issue free service. See attached photographs. Well done RYOBI.

40-VOLT LITHIUM-ION 2.0 AH BATTERY, these new Lithium batteries really pack a punch now a days. Battery technology is leaps and bounds from the 1990's and these batteries are it. The batteries have a button and you can press to see how much JUICE is left which sure is a bonus now! For such a powerful Lithium battery but yet very light when adding to your tool.

Garbage Battery
Very cheaply made. Last exactly 3 years then they just die with 3 bars left on gauge. Call ryobi and nothing can do because date on battery is 38 months, and his problem started the fall prior year, but figured had to have full discharge and recharge to work properly again. It was last use of season, I should of looked into it then, but still don’t think I had tool for 3 years. Should of kept recipe, but didn’t think it would die that fast. I have dewalt li ion batteries that are 8 to 9 years old and still going strong. Ryobi tools never were any good since they had the blue 18 volt line. They were lucky to last a day on job site. Should of learned from that. Other than that the tool worked great the first year of use if you are the type to buy new ones every year than this is great.
