  • Work well
Size: 2 Packs
Work just fine

  • Other than a slightly different look and feel this seems to be a good replacement.
Size: 1 Pack
I don't have the tools to do an actual output comparison but this seems to work great and last about as long as you would expect. The finish and look is a bit different but that's not really important, what is important is that they are half the price and do the same the thing. I've only had it for one season but if it starts failing early I will update. ... show more

  • It works but not as well as the branded item.
Size: 1 Pack
I recently purchased the DTK Battery Replacement for my Ryobi 40V power tools, and my experience with it has been fairly average. This battery does have some pros and cons worth mentioning. On the positive side, it charges without any issues and fits perfectly into my Ryobi power washer, so compatibility is not a problem. The fact that it comes at a significantly lower price point than the official Ryobi brand is a definite advantage for budget-conscious consumers like myself. It's a cost-effective alternative for those looking to expand their collection of batteries without breaking the bank. However, there are some notable drawbacks. One of the most significant downsides is its relatively short lifespan when used with my power washer. It didn't last as long as I had hoped, and I found myself having to recharge it more frequently than my other batteries. This could be attributed to the lower amp-hour (AH) rating compared to some of my other batteries, which is a bit perplexing considering that it's lighter in weight. Speaking of weight, it's worth mentioning that this DTK replacement battery is noticeably lighter than my other batteries with lower AH ratings. While this might make it more comfortable to handle and carry around, it doesn't necessarily translate to longer usage, as I had expected. ... show more

  • Perfect replacement or addition for Ryobi 40v!
Size: 1 Pack
The OEM Ryobi batteries are really expensive and this unit is priced at less than half of the original, with all of the same performance. The battery came charged out of the box but I put it on my charger to verify compatibility and it immediately began topping off. After 20 minutes or so the charging was complete so I mounted the battery on my string trimmer and went to work on my half acre yard - It takes 2 fully charged 2.0AH batteries to complete my yard or 1 fully charged 4.0AH, and by the time I finished this battery was still showing half full! I mounted the battery to my blower and there was enough power left to finish the entire task (about 20 minutes worth of work) and the battery still had some life left. Time will tell as to the overall life of the battery, but finishing my entire yard with a single charged battery is outstanding! ... show more

  • Could not get it to recharge.
Size: 1 Pack
Battery was fully charged and worked right out of the box. Problem was that when it needed to be recharged I tired 3 different Ryobi charges and all three showed that the battery was bad and it would not recharge.

  • Does not seem to be the stated capacity, more like 4 Amp Hours
Size: 1 Pack
I have been using Ryobi's 40v system for many years now. My Ryobi mower can mow my yard with our 6 Amp Hour battery with 1-2 bars of charge left. This battery is the size of our small, 2.6 Amp Hour battery and is even lighter than it, however, it claims to be 6.2 Amp Hours in capacity. If you look at my picture, this battery is on the right and claims to have more capacity than the battery on the left. Maybe this is made of flat cells rather than the typical cylinder cells that my other packs are made of. This would give it more energy density. Based on my own real-world usage, I would estimate the capacity to be 4 Amp Hours. It is certainly not the 6.2 Amp Hours that are stated, but it is considerably higher capacity than the Ryobi 2.6 Amp Hour batter that is the same size. I really do wish they correctly stated the actual capacity. Otherwise, it charged, and I was able to use it exactly like the OEM batteries. ... show more

  • Works perfectly with my Ryobi string trimmer.
Size: 1 Pack
I have a large yard that needs a lot of trimming with a string trimmer. I like the battery powered one because it is quieter. My problem is the battery runs down before I'm done and I have to wait for it to recharge. This battery solves that problem. It is a perfect fit and recharges with my original charger. My other battery is a 5Ah battery so this one has a slightly larger capacity. ... show more

  • So far, perfect replacement with tremendous value!
Size: 1 Pack
Charged right up to 100% on the charger my tool came with, so zero issues there. The battery seemed to be significantly more powerful than the OEM one that I used all summer long. I fully understand that every new battery will be optimal for a little while, but this one seemed to make the tool perform better than it ever did with the older battery. Super satisfied here, fits everything perfect and the performance is top notch. ... show more
