## Questions & Answers

**Q: Can a ryobi 6 ah battery be used in a 4ah mower and a 4ah charger?**
A: The charger that comes with this 4ah battery does not work with my 6ah battery. It flashes red to show a fault. I have a 6ah battery that came with my mower. I bought this 4ah battery as a secondary to be able to finish the lawn in one session.

**Q: how do i charge**
A: Use the charger that came with the battery.  When all else fails, read the directions.

**Q: Does this battery fit a Ryobi mower #40180-Y**
A: Yes fit

**Q: Will this work on my Ryobi snowblower?**
A: If your snowblower uses a 40V battery it will work. Though note the ah of the battery in your snow blower.  The higher the ah means less recharging during jobs.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very satisfied
*by V***E on June 19, 2025*

I purchased this for my husband for Father’s Day because my daughters were purchasing the high-powered blower. Both are excellent in ability and in power. It’s so nice not to have the cord behind the leaf blower. We have a large yard and it works well for that.

### ⭐⭐⭐⭐⭐ Best battery available imo
*by S***S on August 30, 2024*

I've purchased 4 off brand 6ah batteries. All died within a year. My original Ryobi 4ah is going strong 4 years later. Power doesn't sag much when put on a heavy load, ex mowing tall wet grass. It does have a overheat protection built in to prevent damage. I have 3 of these Ryobi batteries now and won't purchase other brands anymore. Live and learn. These cost more than cheap off brand batteries, but they pay for themselves by lasting years at a time and having a high steady output. It may be tempting to get 2x 6ah batteries for the price of this one, but don't do it! They have power sags and fail quickly. Save yourself money and buy Ryobi batteries.

### ⭐⭐⭐⭐⭐ Good value and reliable
*by R***. on July 23, 2024*

Knock-off brands of these batteries are cheaper but not always reliable. I have a Ryobi lawn mower I use these batteries for. It came with a 6 amp hour battery which is considerably larger and heavier than the 4 amp hour shown here. For that difference in size and weight it runs maybe 10 minutes longer. So I opted for the 4 amp hour battery. I need to be able to mow for two hours or so and three of these allow that (if I put the first empty battery back in the charger right away so it has time to recharge so I can reuse it without interruption).
