Great to have a warranty replacement "upgrade" me from a 1.5AH to this battery. Larger capacity in pretty much same packaging size. Time will tell the reliability story as charge indicator on previous battery failed.

I now have an awesome collection of Ryobi tools that equip me with all I need for maintenance and DIY around my home. The flexibility of an interchangeable battery system is fantastic.

I recently purchased the Ryobi Long Handle Hedge cutter and 2 amp battery packBoth products have proven to be fantasticThe hedge cutter easily cuts branches around the 15 mm diameter and the 2 amp battery pack kept the hedge cutter operational on and off for well over 90 minutes with 2 bars of battery life left when job completedThe ability to extend the handle up to 3.1 m meant that I could do most of the cutting from the groundThe weight of the hedge cutter is a great advantageSo happy with product I have already recommended this unit to friends

Another battery option for the Ryobi 18V range of products. I like the new design, with the larger LED fuel guage, but would be nice to bring back the rubber base. Not sure if this is an upgrade to the 1.5Ah, or downgrade of the 2.5Ah, but its a good match for the small hand tools.
Great light battery for those devices which don't need the bigger, longer lasting batteries and for those where you want to keep the weight down without any loss of power. The power level indicator is fantastc !
I purchased this battery to replace a 1.5Ah battery purchased in early 2015 with a cordless drill. The drill is still giving good service but the battery no longer holds a full charge. The new battery performs beautifully and seems to charge a lot quicker than the older battery, due to upgraded technology.
These batteries work great and fit all other Ryobi One tools. Also, very quick charging time. I have not had any problems with them
My RYOBI products are definitely not toys and I am so pleased with my purchasesMy RYOBI products are the Cordless Handivac Kit and the Mozzie Zapper Lantern KitThey both use 18V ONE+Compact 2.0Ah Battery so I purchased 2 x 18V ONE+ Compact 2.0Ahbatteries to use in my RYOBI products because conveniently the batteries fit both prodcutsThe batteries recharge quickly so are ready for the next time I need my RYOBI product
What a power packed battery. 20.Ah keeping it up to the larger batteries. What a handy little Battery . Can’t fault it.
I bought these smaller sized batteries to use on my prunning secateurs as I found the 4 AH battery was making the tool too heavy. What a great buy as I can now use the tool all day without fatigue.
