Rated 5 out of 5 by from I love Ryobi battery powered hand tools! I have 4 Ryobi tools plus the 38" riding lawnmower. Two of the power tools are more than 8 years old and continue to perform as new. During that time I have replaced two out of six batteries which I think is not bad based on my experience with other battery powered tools. One of these failed because I left the tool outside in sub-zero weather when discharged - my bad. I expect to get at least 5 years from my batteries and so it's too soon to tell with the new ones but I have confidence that they will do the job for a long time. I like the high capacity, they're a bit heavier but this will be more than offset by the extended charge life on big jobs. Ryobi is my power tool of choice.

Rated 5 out of 5 by from Ryobi 4-Ah 2-pack Great buy in Feb. 2021 on sale -- 2-pack for $60. Charged them up, and they worked fine in drill and impact driver. So far, only occasional use. The real test will be using them over time in Ryobi chainsaw and string trimmer.

Rated 5 out of 5 by from Great value in this 2 pack! These batteries are a great value considering how long they last. They are obviously a bit heavier than the smaller options but they don’t make the tools awkward to use or anything like that.

Hi. Whats the difference between P129 and P197? Thank you.

Asked by: Keith
P129 is a 2 pack battery from what I understand, 18V 4.0 ah High Capacity. P197 is basically the same as the P129, 18V 4.0 ah battery but has a faster charge rate, the P197 is a single battery that the sell. I bought the two-pack so I would always have a charged spare.

What is the difference between Model #P129 and PSK003? i just picked up PSK003 but realized that P129 is much cheaper.

Asked by: SZamma
Hi SZamma, PSK003 includes (2) 4.0Ah batteries and (1) 18v charger where P129 only offers (2) 4.0Ah batteries. The only difference between the batteries is the colors. We hope this information helps. Thanks for reaching out, RYOBI Canada.

I have P102 and P108 for 2 different tools. Both are "18V ONE+" as well. If I buy P129 (2-Pack) for replacement, all compatible as they are all "18V ONE+" ?

Asked by: Chris
Hi Chris, Yes all of the above batteries will be compatible with all RYOBI 18V products. In fact, all 18V batteries (1.3Ah - 9.0Ah) will work with all of our 18V tools. Thanks for reaching out, RYOBI Canada.

I dropped a RYOBI 18V High Capacity 4.0 Ah Battery in a bucket of water. When I press the battery light, one light flashes green. How do you recommend drying it out?? I shook the water out and opened a corner of the case and left it in the sun to dry.

Asked by: Lobster
Hi there, There is not a specific method to dry the out. Be sure to let it sit in the sun or your garage for a bit of time before using it again. Thanks, RYOBI Canada.

Can I use the P117 charge for these batteries?

Asked by: GaryC
Hi Gary, Yes of course you can, all of the chargers other than the old NiCad chargers (blue) can charge any battery. Thanks, Ryobi Canada

Hi,  can I use the P113 charger to charge the P129 batteries? 

Asked by: Winston
The P113 charger was designed for Ni-Cad batteries and has been recalled by Ryobi.  The P129 batteries are Lithium batteries and require the newer charger.  The charger for the Lithium batteries will, however, charge both Lithium and Ni-Cad batteries.

will the lithium battery work on the charger BD0534 or do you have to buy a new charger

Asked by: tcscroller
From what I can tell that is a Craftsman charger. You would need to buy a charger.
