Bonacell 2 Pack 4000mAh 12V Replacement Battery Compatible with RYOBI CB120L CB121L BPL-1220 130503001 130503005, 12V Lithium Battery (NOT for CB120N)

One would work, the other one would not work, I'm still waiting for the other one.

I received the batteries today!I charged both of them and usedThey work great . Thank you great price, fits great, just like the original.

These catteries arrived with one pack unable to be charged with a standard Ryobi charger designed for CB120L batteries (tase batteries are claimed to be direct replacements for the Ryobi CB120L Battery. The capacity of 4000 mAr is also falsely claimed. The other battery was able to accept a full charge. However, the life of the fully charged battery was equivalent to the original Ryobi battery I was replacing which is less than half of the advertised 4000 mAh capacity. The performance leads me to believe the cells used in these battery packs are 2000 mAh.Bottom line, if you want to purchase two batteries that each have approximately 2000 mHr capacity and if you are lucky enough to get two that work, then go ahead and purchase these units. If you want a truly high capacity battery of 3000 to 3500 mAh, then look elsewhere, you're wasting your time buying these.

Great replacement batteries

They came really quick and was able to charge them and they work great.Glad that I had purchased them.

does a great job

Does not fit Ryobi tools as claimed, so it is NOT a replacement for a Ryobi CB 121 L as claimed.

Petfect fit for my older Ryobi drill.
