## Before you buy

- Listing details are inconsistent: the title and feature text specify 7,500mAh, but the stated 40V specification appears as malformed text and is excluded from the technical table. The listing also gives differing compatibility lists, explicitly says it does not fit RY40002 and RY40408, and does not confirm that every listed tool or charger is compatible. Check your exact model before purchase.

## A good fit for

- Ryobi 40V tool owners seeking a two-pack of claimed replacement batteries who can confirm their exact tool and charger models against the listing.

## Less suited to

- Buyers who need confirmed fitment for a model not clearly covered by the listing.
- Buyers seeking a battery-and-charger bundle. No charger is specified as included.

## Customer feedback

Only a very small number of aggregate ratings are supplied, and they are split between high and low star categories. That is too little evidence to identify dependable strengths, problems, or reasons for the ratings. Buyers should weigh this uncertainty against their need for confirmed tool compatibility and the stated capacity.

## Frequently asked questions

### How many batteries are included?
The listing describes two lithium-ion batteries as included and identifies the product as a two-pack.
### What capacity does the listing claim?
The title and feature text state 7,500mAh. This is a listing claim, not an independently verified measurement.
### Which Ryobi tools and chargers are compatible?
The listing names a range of Ryobi 40V tool and charger models, but its compatibility lists are inconsistent and it expressly excludes RY40002 and RY40408. Check the exact model before buying.
### Is a charger included?
The supplied package information lists two batteries and one user manual. It does not list a charger.
