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.

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 ### ⭐⭐⭐⭐⭐ Best battery available imo *by S***S on 30 August 2024* I've purchased 4 off brand 6ah batteries.

No way to mount charger to wall *by S***S on 14 August 2023* This battery charged up fine and works great in my mower. It powered the mower (through thick tall grass) for about an hour. The charger is very lightweight. There isn't a way to mount it the way that, for example, Dewalt chargers have holes that allow you to mount them on screws to a wall. The battery is heavy though, and significantly larger than the charger, so maybe that's why they don't encourage wall mounting. The battery gets very hot when in use, but I was able to touch it with bare hands after mowing for an hour in 100 degree weather. It cooled quickly once back inside. Not sure what else to say about a battery and charger but this was my first time using Ryobi anything. I got a Ryobi mower with no battery from my brother, so I bought this battery and charger. I've tended toward Dewalt and Craftsman over Ryobi for power tools, but I am super impressed with the Ryobi mower. Never used anything but gas operated lawn appliances in the past. The power was way more than I expected for a battery powered mower. It chewed through tall grass better than my last gas push mower. Even my gas riding mower slows down with this grass and the Ryobi electric mower was fine. So overall, I'm very impressed with the power this brand packs. I won't hesitate to buy more tools and batteries from Ryobi going forward. ## Frequently Bought Together - Ryobi 40V Battery and Charger Kit 4.0 Ah Lithium-Ion Battery Set OEM OP4040 + OP403A - Ryobi 40V 4.0 Ah Lithium-Ion Battery OP4040 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/713275707-ryobi-40v-battery-and-charger-kit-4-0-ah-lithium](https://www.desertcart.hr/products/713275707-ryobi-40v-battery-and-charger-kit-4-0-ah-lithium) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-12*
