Customer feedback describes the batteries as working well as replacements in Ryobi tools, with some saying charge retention is comparable to original batteries. Battery life is mixed, however, including reports of a unit stopping charging after four months. That matters for a set intended to supply spare power over repeated tool use. The listing's 5.5Ah capacity is a manufacturer claim, not evidence that every unit will deliver consistent longevity.

Positive themes

Customers describe the batteries as useful replacements that work with their Ryobi tools.

Mixed feedback

Battery-life reports differ. Some customers say charge retention matches original batteries, while others report a battery stopped charging after four months.
