## At a glance

- The listing claims compatibility with a range of Ryobi 40V battery and tool models, and names the ZROP401 charger.
- A built-in four-LED indicator is described as showing remaining battery power.
- The listing claims 7.5Ah capacity and says runtime is twice that of a standard 4.0 Ah battery. This is a manufacturer claim, not an independent runtime measurement.

## Pros

- A stated 7.5Ah capacity offers a higher-capacity replacement option than the listing's 4.0Ah comparison battery.
- The four-LED battery indicator provides a listed way to check remaining charge.

## Cons

- Customer feedback reports that battery life can fall short of expectations.

## Before you buy

- Compatibility details are inconsistent: the listing names OP40602 among compatible battery models, but its later part-number list omits it, and the tool list explicitly excludes RY40002 and RY40408. Charger compatibility is stated for ZROP401, while customer feedback reports mixed charger compatibility. Verify the exact tool and charger model before buying. The title and listing identify a 7.5Ah battery, while the technical capacity is listed as 7500 milliamp\_hours and amperage as 7.5 A. The claimed twice-the-runtime comparison is not independently substantiated. The manufacturer says the battery is shipped not fully charged and recommends charging at least once every 2–3 weeks during extended inactivity.

## A good fit for

- Ryobi 40V tool owners looking for a single replacement or spare battery, after confirming their specific tool and charger are listed as compatible.
- Buyers who value a built-in charge indicator and want a battery listed at 7.5Ah.

## Less suited to

- Buyers who need a charger included. The listing says the charger is not included.
- Buyers who require verified runtime or guaranteed compatibility with a specific Ryobi tool or charger.

## Customer feedback

Customer feedback highlights perceived good quality and quick charging, alongside reports that runtime can be shorter than expected. Compatibility experiences are mixed, including reports of charger-related problems. That matters for buyers considering this as a long-running spare or relying on a particular tool and charger pairing. The listing's 7.5Ah capacity and broad compatibility claims do not establish real-world runtime or compatibility for every model.
- Positive themes: Customers mention good quality and quick charging.
- Negative themes: Some customers report that battery life does not meet expectations.
- Mixed feedback: Compatibility feedback is mixed, with some customers finding the battery suitable and others reporting charger-related issues.

## Frequently asked questions

### Does this battery include a charger?
No charger is listed as included. The listing explicitly says the charger is not included.
### Which Ryobi tools are compatible?

The listing gives 7500 milliamp\_hours and describes the battery as 7.5Ah. Its claim of twice the runtime of a standard 4.0 Ah battery is not independently verified.
