Purchased a 4 pack of 4ah batteries for $249. Great value. So far have used on my grinder, impact wrench and air compressor, all have performed flawlessly. Very happy with my purchase.

Needed some extra battery capacity for off grid camping. These puppies powered the light, kept the phones charged, pumped up the beds, and powered the drill for the screw in pegs with power to spare.

I tried to take a shortcut and buy some Ryobi-compatible batteries online... they were trash. These REAL Ryobi batteries work so well - I'll only be buying the real thing from Bunnings from now on!

Bought to use with the 18V spotlight skin. Does the job and one battery provided plenty of run time. Shame the batteries are quite expensive. Previous 4AH battery lasted 4 years before developing issues.
Who doesn’t need more batteries? There’s nothing worse than having half a job done and being forced to wait for battery to recharge. This pack is an excellent addition to our battery collection to enable switching of battery mid job
I have the 1x 2amp/hr, 2x 2.5amp/hr and 2x 4amp/hr. Depending on the job I am doing and the tool I am using, it is great having that choice if battery size and weight. If I got a big job on, its great knowing I got heaps of life with this 4Ah and a backup waiting. If I got a little job or a painful job (eg. putting metal screws in above shoulder level) , its great having the smaller and lighter batteries.
The 4Ah battery packs plenty of punch for my Ryobi tools. The weight they add is not excessive and their endurance is good. I have found them to be reliable and they charge quickly in the Ryobi charger.
It's great to have these extra batteries for my Ryobi One tools.I can have one battery in each tool (I have 16 at home and the holiday house).So I always have some on charge to take with me.I had tried some cheaper batteries but they didn't hold the charge and had a very short life.Ryobi batteries last much longer !
Of all the batteries I've purchased for my Ryobi gear, the 4.0Ah one has outlasted all of the rest. I recommend anyone purchase this specific battery as its the best overall for long lasting both in use and when not in use.
I currently have two batteries, one 2.0Ah and one 4.0Ah. I bought a blower for general use but it was used a lot more than I thought I would. Whilst using my electric hand drills I found that I would flatten them before finishing the job. I then bought a package of 2 x 4.0Ah batteries which now give me greater flexibility to finish the jobs. I have no hesitation in recommending them but I did find the price of approx. $200 a bit much.
