Good News/Bad News - and a word of caution
Bought op4050 (5 amp) model because my 2-year old 2.6 amp battery would only run chainsaw for 15 minutes. Charged my new battery overnight and it ran for... 8 minutes! Good news is that warranty 800 operator was friendly and is shipping me a new battery. Bad news is still have to wait two more weeks for a decent battery. Date code incidated battery was produced 15 months ago. This again confirms lessons I have painfully learned about Ryobi batteries. If you buy from anyone other than Home Depot, Ryobi WILL NOT honor a warranty. It sucks how expensive these batteries are, but bite the bullet, but from Depot, and keep your receipt and order number for the full three years.

      BATTERY NEEDS IMPROVEMENT such as thermal management ,over load protection
      I used this battery for about 2 years for lawn mower and cutting tree branches. Good and strong power. Easy to recharge and satisfactory amount of time last long. After I used with 14 in chainsaw and cut the 7 inchs tree root, battery was unable to recharge and defective . I don't have problem with 4-5 inches tree branches.

        Ryobi battery problem
        I have 4 tools, leaf blower, weed trimmer, leaf vac, and chainsaw that run off of this type of battery, Within 1-2 years of purchasing these tools/batteries online and some from the home depot store, only one (1) of the four (4) batteries work good, two have failed completly, and 1 only works 2-3min now, the only good one lasts me about 15min. There’s no reason why these batteries should have failed so quickly. Ryobi need to fix their faulty batteries.

          Try this first before you buy!
          If your battery won't charge and flashes all four LEDs when you press the test button, try this first to reset it.

            suck
            i have the Ryobi lawn mower, weed eater and blower all three batteries absolutely suck. All 3 can't keep a charge. The lights will say they're fully charge put them on the equipment and last 5 minutes (if lucky) 1 of them are the 3Ah and 1 is 4Ah and the other 5Ah. They equally suck.

              RYOBI is the best product out there. Large selection of 40v power tools. I hope they can offer a combo blower & vacuum unit. A trade in/upgrade option would be great.

              I lacked about 20 minutes of getting my entire yard done. Bought an extra battery and now have enough power to do it all in one try. Would sure recommend the Ryobi battery mower to any and all that are thinking about getting one.
