ADVTRONICS 2 Pack 5000mAh 18V Lithium P108 Replacement Battery Compatible with 18-Volt ONE+ Battery P102 P103 P104 P105 P107 P108 P109 P190 P191 P122

These batteries work better in the less demanding tools but that's not much of a surprise... they go for days in the radio, work as well as the OEM in the drills, but battery life is not as great as the OEM in nailguns or circular saws. But with this price, and the fact I have several chargers, they can still be used in any of my growing collection of Ryobi 18V power tools. 5 stars overall but only 4 for battery life...(OEM batteries compared to are the Ryobi P122 4AH 18V)

I would recommend these if you are using non brushless tools. While these worked in my new brushless miter saw for 2 days in a row I did notice it lack that extra power. I contacted Ryobi and found that I needed the HP batteries. So I ended up returning these.

Added these batteries to my set up Ryobi tools. Both batteries came 3/4 charged and worked within all my tools. They appear to have the expected life to the battery.

Charged the batteries on arrival and they are working great so far. I haven't had them long enough to know how long they will last with re-charging.

These batteries work great. I can’t tell the difference between these and the name brand ryobi batteries. Would purchase again.

Works as well as OEM. Will need to see about lifespan compared to OEM.

These arrived pre charged. Love them!

Liked the time it took to get, and happy with the product. Seems to do exactly what I needed it do.
