Rated 1.0 out of 5.0 by Disappointed Failed to charge after 8 uses
The Ryobi trimmer came with this battery. The charger indicates after only eight uses (and subsequent charging), that it is defective and will not charge. In fact, the battery had about a 1/4 of a charge when I put it on last and has now drained to nearly no charge. It can only be mounted in the charger one way and was properly mounted. Several attempts, same result. Don't buy Ryobi. It's a shame, because the trimmer is fairly powerful and lightweight. This battery though, worthless. The Home Depot reviews for the trimmer were positive, which influenced my choice. They indicated the 40v would run for an acceptable amount of time, but the 18v were too short.

Rated 3.0 out of 5.0 by MaryTurner love the trimmer and blower, but 2nd battery to die within 4 charges
I love the tools... The trimmer is awesome, the blower is awesome - however I have gone through 2 batteries that dont seem to last more than 4 charges. I dont understand what I could be doing wrong. I will begin to use the tool and it will randomly stop working. I click the battery tester and it shows full charge. I try again and sometimes the tool will begin to work and allow me to finish the job. However this is the identical symptom right before the battery can no longer be charged. 2 batteries dead within 60 days of purchase. I will exchange it again at home depot but it really hurts my feelings. I LOVE THE TRIMMER, but HATE THE BATTERIES...

Rated 1.0 out of 5.0 by akaleek Faulty product
I bought this battery as a back-up for the 40 volt pole saw, weed whacker and cordless leaf blower, all of which I purchased this year. I received the battery 2 weeks after placing the order, then attempted to charge it on the Ryobi 40 volt charger. Battery was defective and would not charge. Returned it the next day and purchased another one which I ended up returning 2 weeks later after it quit working. I purchased a third one...we'll see how long this one lasts! I really regret purchasing any of Ryobi's 40 volt tools due to the short life of the batteries.

Rated 1.0 out of 5.0 by Grandpaof13 Beware this Battery-Expensive for Less than Five Charging cycles
Purchased two of these batteries for use with a Trimmer, RY40002. Neither battery made it to five cycles without failing (charger gives alternating Red and Green flashes).
$99 is too much for a battery that can't make it through 5 cycles. Read a review that said the batteries need to be stowed indoors, but our garage hasn't gone below 50 degrees, or above 90. Any product designed for outdoor use should be able to handle that temperature range.

Rated 4.0 out of 5.0 by MrHedgeTrimmer seems to work ok
I haven't had the battery for long so I can't give much of a review. I used it in a hedge trimmer and was amazed how powerful it was.
My only complaint is that Home Depot does not sell the charger or batteries in the stores. They claim they do but I went to 3 stores that indicated they had them in their inventory just to find out they did not. I had to buy them online which isn't normally a problem but I wanted them before my party on the weekend. Ah well.

Rated 1.0 out of 5.0 by Disappointed Poor batteries
Tools are great. Batteries are NOT! Replaced twice in less than 60 days. Shame Ryobi can't get their batteries right..this would be a nice set. As it is..it's useless! VERY DISAPPOINTED!!

Rated 2.0 out of 5.0 by limy disappoined in life of battery before recharge is needed
purchased this as a back up as original battery charge only lasts for 20 minutes of weed eating then when i got it home it was defective and had to return to the store for an exchange hope this isn;t a sign that this battery will provide even less up time than my original version these tools are a great idea but battery charge/use time needs improvement
