Review on Long-Lasting Replacement Battery For Ryobi Power Tools - CB120 400MAh 12V Compatible With CB120L, CB121L, BPL-1220, 130503001, And 130503005 by Hugh Starr

This Ryobi replacement battery just works as it should. No issues with it in my tools. Charges on the Ryobi battery charger as it should. Battery charge seems to last as long as the original Ryobi battery that came with the set of tools I bought roughly15 years ago.Original finally died and needed a new one. Turns out Ryobi does not sell them anymore. Glad I found this replacement battery. Looking forward to another 15 years. Per use cost on this set of Ryobi tools is getting about as close to zero as you can get. $200 divided by 15 years = $13.33 per year, use the tools at least once a month so $13.33 divided by 12 = 1.11 some months use pretty much every day.
