Pretty good run time however, with most knock off batteries, the battery level indicator is not accurate. I wish Makita made a high power battery. Overall, I do recommend this battery. Review: I'm happy with them. - HEAVY, BUT DOES A GOOD JOB, I've had my two batteries for over a year now and although they are heavy, they are not unmanageable. They work on all my Makita products, especially the chain saw. I use the Makita charger and so far I am very pleased with them. I'm about to order two more and I'm hoping they are of the same quality. ## Features - Voltage:18V Capacity:9.0Ah(9000mAh), Battery type:Li-ion - New design：with LED indicate lights is percent capacity display, avoid excessive use and improve working life - Compatible with original 18V Cordless Power tools and original chargers - Electronics control charge & discharge analytics to optimize performance and extend life - Any questions(problem), 24-hour friendly customer service ## Images ![waitley 18V 9.0Ah Replacement Battery Compatible with BL1830 BL1840 BL1850 BL1860 BL1890 Lithium-Ion Battery Tools with LED Indicator - Image 1](https://m.media-amazon.com/images/I/61kuOi9JhQL.jpg) ![waitley 18V 9.0Ah Replacement Battery Compatible with BL1830 BL1840 BL1850 BL1860 BL1890 Lithium-Ion Battery Tools with LED Indicator - Image 2](https://m.media-amazon.com/images/I/51iyikHYATL.jpg) ![waitley 18V 9.0Ah Replacement Battery Compatible with BL1830 BL1840 BL1850 BL1860 BL1890 Lithium-Ion Battery Tools with LED Indicator - Image 3](https://m.media-amazon.com/images/I/61wmXPPlhUL.jpg) ![waitley 18V 9.0Ah Replacement Battery Compatible with BL1830 BL1840 BL1850 BL1860 BL1890 Lithium-Ion Battery Tools with LED Indicator - Image 4](https://m.media-amazon.com/images/I/61uxBc6Sm4L.jpg) ![waitley 18V 9.0Ah Replacement Battery Compatible with BL1830 BL1840 BL1850 BL1860 BL1890 Lithium-Ion Battery Tools with LED Indicator - Image 5](https://m.media-amazon.com/images/I/61sLMWrHPZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good battery *by G***A on January 12, 2025* Had this battery for a couple years now been a good battery no problems last quite a while.

Overall, I do recommend this battery. ### ⭐⭐⭐⭐⭐ I'm happy with them. *by J***I on November 4, 2025* HEAVY, BUT DOES A GOOD JOB, I've had my two batteries for over a year now and although they are heavy, they are not unmanageable. They work on all my Makita products, especially the chain saw. I use the Makita charger and so far I am very pleased with them.

The batteries are huge, and almost 2x the weight of my 5AH name brand batteries so be ware of that as wll. I'm using them in a 36V pair on a leaf blower. The name brand 5AH batteries last 15-20 min on average. So these should give me 27-36 min of life. I'm getting more like 18-25min range. So these are equivalent to about a 6AH name brand battery. LiON batteries sometimes take a few charge cycles to give a full life, but after about a dozen charges I swear I'm getting a few min less, not more. they also tend to over heat and shut down at about 2/3 discharge where my name brand ones do not. If I give it a couple min break half way though they don't do this. If they do shut down, wait about 5 min and they will come back to life again with the meter changing from 0% to, in my case, about 40%. That said these are also 1/3 the price of the name brand so it's still a good deal. I wouldn't get these for your main batteries but for a back up or additional pair they are a good value. --- ## 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.tn/products/67709780-waitley-18v-9-0ah-replacement-battery-compatible-with-bl1830-bl1840](https://www.desertcart.tn/products/67709780-waitley-18v-9-0ah-replacement-battery-compatible-with-bl1830-bl1840) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
