Review: Great battery system. - I purchased 2 of these batteries while they were on a special discounted price and a Greenworks G40UC4 40V Fast Charger. The reason I bought 2 batteries was to allow me to charge a battery while using the other. The batteries recharge fully using the fast charger in under 30 minutes while a larger 4ah would take 60 minutes but last longer and was more than twice the price. You do need to bare in mind that once the battery has been used it will not charge straight away as the charger recognises high temperature. The battery can be placed on the charger and the built in fan cools the battery in 15 mins before recharge starts. My only slight complaint is the time it takes the batteries to run out of charge. I also purchased the GD40LM46SP 40V Lawn Mower 46cm Self-Propelled on a special price from desertcart and the battery lasts 15 minutes if I cut and use the self drive. The mower by the way is brilliant (see my other review). I have a large sloping uneven garden so really I should have bought 3 batteries or a larger AH rated battery but that was costly. All in all a great system that I would highly recommend. Review: Buy the real thing! - A well made battery that is consistent in output. I would however have liked to be able to purchase the 4Ahr. model since using it with my strimmer blade it only lasts for a few minutes. These are seemingly a little scarce at the moment, it means that for me to get 4Ahrs. I have to purchase two batteries so the cost jumps up considerably. Still with that said, the heat build up in them is less, and I suppose that will lead to a longer life span for the 2Ahrs. type. I did have a so called 5Ahr. copy of the battery that performed perfectly for three or four discharge and recharge cycles, then it died, shorted cell or cells internally, can I get a replacement no chance. In conclusion do not buy copies, they are rubbish and you have no actual warranty with them since to send the back to the supplier is at your cost and they then tell you that you have abused the battery. Stick to the real thing, you can be sure that the warranty is real, in the unlikely chance that you need it. ## Features - POWERFUL LITHIUM ION BATTERY - The battery offers more power and longer run times - ideal for our cordless tools, such as lawn mowers, pressure washers and chainsaws of Greenworks - BATTERY - The battery comes with a LED battery charge indicator and can be charged at any point even if it is not fully discharged with no memory effect - CHARGER - The integrated LEDs of the Greenworks charger show you whether your battery is charging or already fully charged and is equipped with an easy and convenient battery slot - POWERFUL- Greenworks Tools's battery charger with a convincing output of 90 W/2 A and thanks to the battery management system you always have the battery status of your garden tools in view - ONE BATTERY FOR ALL - The Greenworks 40 V batteries from 2 Ah to powerful 6 Ah are versatile and compatible with many Greenworks products of the garden and workshop range ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08VFT99H1 | | Batteries | 1 Lithium Ion batteries required.

Do you know if they are compatible?** A: I'm afraid it is NOT compatible. Each OEM tends to make a form-factor unique to it's range of tools (no surprise there!!) **Q: Does this fit the Qualcast lawnmower?** A: Only green. Works appliances of the same voltage and ah **Q: How long to charge at first?** A: Hi Gary, not too long. About 1 - 2 hours. When you're mowing/strimming etc., and you exhaust the battery, it will be quite warm and won't charge until it has cooled down (generally after about 30 mins). Hope this helps **Q: When battery is fitted to charger both lights immediately go out, with no battery in place charger power light stays on what needs replacing ?** A: Under normal conditions, a flashing LED indicates that the battery is faulty - remove for 1 minute, unplug the charger and retry. If LED still flashes, replace the battery. If both lights go out, the battery is less than 10% charged - leave it in the charger and check the progress by pressing the BCI button. If the BCI remains unlit, then replace the battery. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great battery system. *by S***L on 5 April 2021* I purchased 2 of these batteries while they were on a special discounted price and a Greenworks G40UC4 40V Fast Charger.

Takes about 45 minutes or so to charge up the 40v battery. The main criticism I have is around battery cooldown. It often treats freshly drained batteries as too hot to charge, but the fan on the device doesn't cool the batteries down particularly fast, so it can take a little while for the charger to actually begin on hotter summer days. Overall though it's been a great addition to the Greenworks arsenal and helped greatly in getting my grass cut without needing to stop and wait for the standard charger. --- ## 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.us/products/394479869-40v-battery-and-universal-charger-kit-2ah-lithium-ion-battery](https://www.desertcart.us/products/394479869-40v-battery-and-universal-charger-kit-2ah-lithium-ion-battery) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-15*
